JP Domain Name
Registry ReportJapan Registry Services Co.,Ltd.

Introduction

The Internet is being used in increasingly diverse areas of society as technology
advances. Along with that, the need for domain names and the importance of domainname system (DNS) are also being strengthened.
With this background, the number of registered General-use JP domain names
surpassed one million in September 2017. In addition, the number of JP domain names
marked 1.5 million in February 2018. Over 400,000 names are registered under “co.jp,”
making it the most registered category in the Organizational Type JP Domain Name,the domain name space categorized by organizational type of registrants. 97% of
publicly-listed companies in Japan have already registered “co.jp” domain names,
which indicates that many businesses are using “co.jp” names for their corporatewebsites.
With respect to the trend of the global domain name industry, the new gTLD introduced
through the New gTLD Program of ICANN are becoming popular; increase the chanceof seeing the websites using the new gTLD domain names. On the other hand, various
challenges have continued to threaten the Internet infrastructure such as DDoS attacks
exploiting the mechanism of DNS and detection of vulnerabilities in DNS software.
As a company supporting the basis of the Internet society through domain names and
DNS, JPRS is striving to make the Internet safe for everyone to use. To this end, JPRS
promptly provides information and deals with risks and challenges related to domainnames and DNS as they arise. JPRS also actively contributes to discussions of global
issues and conveys relevant information to the communities in Japan.
In addition to the above, JPRS is committed to its ongoing operations to improve JP
domain name services, develop systems, and carry out promotional activities tofacilitate the use of JP domain names and deliver greater value to users.
The management and administration of JP domain names require a high level ofcommitment to enhancing the public interest and getting ahead in the competition.
Recognizing this vital nature of its services and influence on society, JPRS carries out
its tasks and publishes the annual “JP Domain Name Registry Report” on its
management and administration of JP domain names.
JPRS will continue to ensure that JP domain names remain useful and contribute to thedevelopment of the Internet society.

Goal of JPRS as the JP Domain Name Registry

Our main objectives as the registry are: to continuously improve the value of JP domain names; to gain stronger
support from the local and global Internet community; and to provide domain names as well as management andadministration services that contribute to society in an environment where JPRS competes and collaborates withother registries of TLDs*1 and similar service providers.
JPRS defines the following as the core concepts for the registration and administration of JP domain names.
Reliability: establishing domain name space with the public trust
Stability: operating and administering the stable domain name system (DNS)
Usability: providing accessible domain name services which meet users' needs
Fee Performance: providing services at reasonable fees
With the mission of supporting the Internet infrastructure, JPRS considers it important to ensure reliability andstability while pursuing a good balance with usability and fee performance.

Revision of Free Cartoon Booklet on “How the Internet Works” and Distribution to
Educational Institutions across Japan (May)“Info-Communications Promotion Month” is a nationwide initiative that has been
conducted as part of Internet-related educational activities. In line with this, from May
16 to July 31, 2017, JPRS set up channels including a special website “http://マンガで学ぶ.jp” (learn from Manga) where junior and senior high schools and technicalcolleges could apply for the distribution of educational material produced by JPRS.
JPRS distributed the material free of charge to those who applied. Recognizing thegrowing importance of Internet-related education and shortage of teaching materials inschools, JPRS has worked on this project since 2010. The number of copies distributedin these eight years surpassed 240,000.

Start of Accepting Concurrent Registration Applications for Japanese JP Domain Names
Representing School Names (October)
JPRS started accepting applications for Japanese JP domain names representing the names of elementary andsecondary educational institutions (school names) such as “○○小学校.jp” and “○○高校.東京.jp” on October 2,
2017.
Following its announcement in October 2016 about the launch, JPRS solicited comments from school officials
about the service and improved the registration rule to address the actual situation in the field of education. As partof the effort, JPRS amended the rule concerning the following two school categories that have a specificabbreviation: “中学” for “中学校” and “高校” for “高等学校.” Under the revised rule, only those schools andfounding entities that have already registered either the string of their official school name or the abbreviation canregister the other string. JPRS also extended the Concurrent Registration Application Period longer than originallyplanned, to give each school enough time to consider and an equal opportunity to register desired domain names.

JPRS Held 8th “.jp DNSSEC Key Ceremony” (October)In public-key cryptography, a key ceremony is a procedure that a unique pair of private and public keys is
generated. In JPRS, a key ceremony, or .jp DNSSEC Key Ceremony, is a procedure creating key- andzone-signing keys and signing the jp zone.
It is vital to ensure the reliability and stability of DNSSEC that the procedure for generating and managing the key
pairs is properly and securely executed. For this reason, JPRS invites External Witnesses, who are not affiliatedwith JPRS, to the .jp DNSSEC Key Ceremony. In the .jp DNSSEC Key Ceremony held on October 3, twoExternal Witnesses observed and confirmed the process.

1. Participation in ICANNICANN*1 is a private non-profit organization established in the UnitedStates in 1998 to coordinate globally the resources underpinning theInternet, such as domain names and IP addresses.
Since its foundation, JPRS has been actively participating in theorganization of ICANN and various policy discussions, and supporting
the facilitation of Internet resource management led by the private
sector, with ICANN playing the central role. In 2002, JPRS signed a“ccTLD*2 Sponsorship Agreement” with ICANN, and has since been

By participating in various organizations established within ICANN, as well as by giving presentations andinformation exchanges at various sessions, JPRS participates in policy development andimplementation-planning to cope with issues facing ICANN and registries. Also via ICANN, JPRS is sharing its
experience in JP registry operations with the global community, thereby contributing to the development of theInternet as a whole.
In June 2017, JPRS submitted a statement to ICANN regarding the Japanese Label Generation Rules for the

Currently, ICANN is working on finalizing the rule, taking the statement into consideration.
ICANN holds three public meetings each year in different regions of the world to enable global stakeholders toparticipate in person and discuss policies and rules for Internet resource management. In 2017, ICANN held its
58th meeting in Copenhagen, Denmark in March, the 59th meeting in Johannesburg, South Africa in June andthe 60th meeting in Abu Dhabi, United Arab Emirates in October.
With the participation of numerous parties interested in ccTLD and gTLD, ICANN has always functioned as animportant forum for information-sharing and discussion on issues on policies and governance concerning domainname management. In addition, Supporting Organizations (SOs) and Advisory Committees (ACs) continued
active discussions between different SOs/ACs to gain a better understanding of each other in 2017, like they did
in 2016. ICANN is serving as an important forum for SOs/ACs to exchange views on different topics of interest,with a focus on Internet resources.

In June 2017, Hirofumi Hotta of JPRS was awarded the Multistakeholder Ethos Award by ICANN. He wasrecognized as a well-qualified recipient who has devoted himself to the activities in ICANN and demonstrated thespirit of collaboration for promoting community consensus through his 18 years of active participation anddedication*3.
The community discussion that had continued since 2014 resulted in the completion of the IANA*4 stewardshiptransition in October 2016. Currently, SOs/ACs are working on improving not only their structure but also thetransparency that underpins the structure, by publishing the materials and records of their meetings.
The following reports JPRS's activities in the Supporting Organizations and the Advisory Committees within ICANN:(1) ccNSO
ccNSO*5 is one of the Supporting Organizations set up in ICANN to assist its activities. The role of ccNSO is toform a consensus in the ccTLD community on global issues concerning the entire ccTLD space and to makerecommendations to the ICANN Board. JPRS has been a member of ccNSO since its inception in 2003, andHirofumi Hotta of JPRS has served as the ccNSO Council member during the same time.
In 2017, ccNSO listened to the activity reports made by the new framework that had been established after the
IANA stewardship transition, exchanged information and had question-and-answer sessions with the Cross
Community Working Group on Enhancing ICANN Accountability as well as other relevant working groups within
ccNSO. In doing so, ccNSO made an effort to incorporate the views of as many ccNSO members as possible.
In the discussion about the use of country and territory names as TLDs, ccNSO was required to formulate acollective opinion best representing the whole ccTLD community, including ccTLDs not belonging to ccNSO.
Therefore, ccNSO teamed up with the regional ccTLD associations and worked hard to carry out publicity
activities and consultations by sharing information in the face-to-face meetings and on the mailing lists.

The IDN*6 Variant TLD Program is a series of activities to develop Label Generation Rules (LGR) for the rootzone and aims to establish procedures to add non-ASCII scripts to the root zone.
The following two panels are engaged in the activities of the IDN Variant TLD Program:
1. Generation Panel (GP)Each GP is composed of key figures of each language community and experts in linguistics and domain names.
Each GP creates a proposed LGR for a given script and is organized for each script to be added in the root zone.
2. Integration Panel (IP)
IP is a panel of experts in character encoding or IDNs and is tasked with integrating rules developed by the GPs
into a consistent set of LGRs.
The IP was established in 2014, and several GPs for different scripts were formed in 2015. Each language
community has been making progress to date.
The cultural community that uses Han (Kanji) script includes the Chinese, Korean and Japanese communities,
so it is necessary to develop the LGRs that are consistent across those language communities. Therefore, theJapanese community has been working on its LGR in consideration of such necessity. The study is being
conducted in the Japanese Generation Panel (JGP) involving experts representing the Japanese language
community, linguists and registry experts, with JPNIC and JPRS serving as the secretariat. Hirofumi Hotta of
JPRS is leading the initiative as the chair, and Yoshiro Yoneya is participating as a member to contribute his
expertise gained through designing, providing and operating the Japanese JP Domain Name services.
After mutual coordination, the Japanese, Chinese and Korean GPs respectively proposed the LGRs for their own
scripts to ICANN and moved onto separate discussions with the IP. The three-party coordination and thearrangement with the IP were originally planned to be complete by mid 2015. However, they actually concludedin the first half of 2017, as the consultation between the Chinese and Korean GPs took longer than expected.
Upon seeing the results of the consultation, the Japanese GP decided to continue its final arrangement with the
IP into 2018.

01 Registry Activities(3) RSSACRSSAC*7 is one of the Advisory Committees within ICANN that advises the ICANN community and the Board on
matters relating to operation, administration, security, and integrity of the Root Server System.
As one of the operators of the M-Root DNS server, JPRS has been participating in the activities of RSSAC incollaboration with the WIDE Project, the other operator. Hirofumi Hotta of JPRS plays an active role in thecommittee representing both of the two M-Root DNS server operators. In 2017, RSSAC made positive efforts tomake its activities more transparent by organizing the open sessions in ICANN meetings to describe the role andfunction of the root servers and by discussing the whole concept of accountability that the root server operators
should ensure.
In addition, Shinta Sato of JPRS serves as a member of the RSSAC Caucus, which is tasked with assisting thedevelopment of RSSAC documents.

(4) DNSSEC Workshop Program Committee
As part of its efforts to promote DNSSEC, ICANN holds the DNSSEC Workshop in every ICANN meeting. ThisDNSSEC Workshop functions as a forum for registries, registrars, Internet service providers and businesses toshare their experience of deploying DNSSEC and to learn the latest technological trends related to DNSSEC.
Yoshiro Yoneya of JPRS serves on the DNSSEC Workshop Program Committee as a member representing Asiaand plays a part by planning the workshops and informing the other members of the situation in Japan.

12 Registry Report(5) Root Zone KSK Rollover Design TeamDNSSEC deployment in the root zone began in July 2010. It is specified that a rollover of the Root Zone Key
Signing Key (KSK) should be carried out when necessary or every five years*8. In February 2015, ICANN set up
a design team (Root Zone KSK Rollover Design Team) that was tasked with planning the Root Zone KSK
Rollover. The team produced and published for comment a document that defined the roles of the related parties
and the rollover process. The draft was approved by the ICANN Board, which was followed by publication of the
finalized version in March 2016*9. Yoshiro Yoneya of JPRS participated in the design team as a member.
The document is intended for the first KSK Rollover and proposes that the signature algorithm and key size
should be maintained; the KSK should be rolled over on a 90-day window that is set for the Zone Signing Key(ZSK) Rollover; and a fallback should be performed in case of emergency.
The Root Zone KSK Rollover was originally scheduled to take place from July 2017 to March 2018, and so
ICANN started a series of processes in July. However, it found in September that a certain number of resolvers
did not have the new KSK, and so moved forward the date to start signing with the new KSK. The timeline of the
KSK Rollover is yet to be finalized as of the end of January 2018*10.

(6) RA Spec11 Security Framework Drafting TeamThe new gTLD Registry Agreement (RA) requires the registries to periodically assess whether the registereddomain names are being used for malicious purposes and provide statistical reports to ICANN*11.
The report is called “Spec11 3b” or simply “Spec11,” after the relevant part in the RA. ICANN established a teamto draft a guideline for the new gTLD registries (Spec11 Security Framework Drafting Team) in July 2015, so that
ICANN could respond to the inquiries from the registries as to how they should implement the Spec11. Currently
the Drafting Team is drawing up a document containing the points to be considered by the new gTLD
registries.The Team consists of three groups, namely, the Registry Group, the Registrar Group and the GAC*12Group. Yoshiro Yoneya of JPRS participated in the Registry Group.
In the Team, mainly the Registry Group prepared the outline of the document, and then the Registrar Group andthe GAC Group reviewed the draft.
The team finished drafting the guideline in June 2017. Following the public comment period, the guideline wasapproved by the ICANN Board and was officially published in October 2017*13.

3. Participation in Registry Associations(1) APTLDAPTLD*1 is an association composed of ccTLD registries mainly in the Asia Pacific (AP) region. JPRS has beena member of APTLD since 2002. As the registry for JP domain names, JPRS proposes improvements of APTLD
activities, provides information and exchanges views at presentations and discussions so that the ccTLD
community in the Asia Pacific region can gain experience and expertise and raise the level of service standards.
In the APTLD meetings held twice a year, the groups and the organizations related to the region introduced theiractivities and the participants explained what they were implementing and considering, such as the service ofeach ccTLD registry and efforts to improve the security of domain names, which led to active discussions.
At the APTLD Ho Chi Minh Meeting held in February, Hirofumi Hotta of JPRS shared the update of ccNSO of
ICANN as a member of the ccNSO Council. He also reported about ccNSO and served as a panelist in the IDN
session in the APTLD Tbilisi Meeting in September. In 2017, APTLD meetings focused on the discussion on
country and territory names and other geographic names as TLDs. The participants shared information anddiscussed the issue in both the February and September meetings, which resulted in the publication of thestatement of APTLD.

(2) CENTR
CENTR*2 is an association consisting of ccTLD registries mainly in Europe. As an Associate member, JPRS
shares information and exchanges opinions with other CENTR members. In addition, CENTR conducts surveys
and information-sharing among members, so JPRS is actively taking part in these activities to consider its futureservices in the light of what it learns in CENTR.

4. Other International Activities(1) Participation in the Internet Governance Forum (IGF)
IGF*1 is an international conference organized under the auspices of the United Nations (UN) and has been held
annually since 2006. IGF 2017 was organized at the United Nations Office at Geneva, Switzerland in December.
Hirofumi Hotta and Yuri Takamatsu of JPRS participated in the event and joined the sessions including the one
related to the IGF Regional and National Initiatives (NRIs)*2.
This particular IGF was the second forum to be held since the UN General Assembly decided to extend IGF for
ten years after 2016. The participants of IGF 2017 reconfirmed the significance of multi-stakeholder dialogues
and the importance of putting the discussions and opinions exchanged locally and regionally onto the agenda of
the global IGF.

(2) Participation in Asia Pacific Regional Internet Governance Forum (APrIGF)
APrIGF*3 has been held annually since 2010, with the participation of mainly the members of the community in
the Asia Pacific. It has been a forum for discussing issues related to Internet governance in not only the APregion but also the entire world. Hirofumi Hotta of JPRS is on the Multi- Stakeholder Steering Group (MSG) thatconsiders the policy of APrIGF.
The 2017 APrIGF was held in Bangkok, Thailand in July, and Hirofumi Hotta and Yuri Takamatsu of JPRS
participated in the event. Hotta took part as a panelist in the session on IDN, where he shared the background to
the introduction of Japanese domain names and talked about the latest trends in Japan as well as the JapaneseLabel Generation Rule for the DNS root zone. The 2017 APrIGF not only dealt with various current topics likecybersecurity, but also continued to develop an outcome document to deliver to the global IGF as a collective
voice formed in the APrIGF, which was introduced in 2015 for the first time. As part of the effort, several sessions
were held in the 2017 APrIGF to hear opinions about the draft outcome document. First, the secretariat andvolunteers developed the draft outcome. Then, following the review carried out during the 2017 APrIGF and thesubsequent public comment period, the outcome document was released to the public.

The IGF recognizes the efforts being made at local and regional levels to promote discussions pertaining toInternet governance as the IGF Regional and National Initiatives, provided they fulfill certain requirements.
In the case of Japan, Internet Governance Conference Japan (IGCJ)*4 and IGF-Japan*5 jointly applied to the
IGF under the name of Japan IGF*6, a single national IGF they established for the purpose of mutual
cooperation and evolution of both initiatives. The Japan IGF was recognized by the global IGF in November
2016.
Hirofumi Hotta of JPRS was involved in forming the Japan IGF as a member of the “IGCJ Coordination
Team” and has been discussing its operation. In the IGF held in December, he ran the session proposed by
the Japan IGF to share the current status of IPv6 deployment in each country and exchange opinions.
As for the activities of the Japan IGF after 2018, IGCJ and IGF-Japan discussed how they could collaborate
going forward.

for the Future

JPRS has constantly worked to strike a proper balance among reliability, stability, usability and fee performance,
which constitute the basis of JP domain name registry services and JP DNS operation, while also improving
each of the four values.
JPRS announced the service outline and the launch schedule of the Japanese JP domain names representing
school names in 2016. Following the announcement, JPRS solicited the views of school officials and improved
the registration rule to address the actual situation in the field of education. It started accepting applications forconcurrent registration in October 2017.
JPRS has also strived to make JP domain names easier to register and use. As part of the effort, it has lowered
the registration fee applied to JP Registrars in a phased manner, while continuing a balanced enhancement of
reliability, stability and usability. In 2017, JPRS reduced the fee for the registration of General-use and Prefecture
Type JP domain names.
JPRS also tapped into its expertise as the JP domain name registry to provide information related to domainnames and DNS and promote understanding of industry trends at events and meetings held in Japan andoverseas. It continued to collaborate with the various communities relating to the Internet and actively contributed
to relevant activities including standardization of Internet technologies. Issuance of RFCs co-authored by JPRS
engineers exemplifies these efforts.
The year 2017 continued to see a number of incidents threatening the stable operation of the Internet, such as
urgent and serious DNS software vulnerabilities and large-scale DDoS attacks exploiting the mechanism of DNS.
JPRS collaborated with other relevant organizations and responded to these problems by alerting the community
with a summary of the incidents as well as countermeasures against them.
As part of its Internet-related educational support activities, JPRS has distributed a free booklet on how theInternet works to educational institutions across Japan for eight years in a row. In 2017, it revamped the booklet
to reflect the trend of Internet usage of recent years. The number of copies distributed in these eight years
exceeded 240,000. JPRS also collaborated with Gakken to produce a learning material for elementary school
students and donated copies to elementary schools and public libraries throughout Japan. Furthermore, JPRS
provided domain names free of charge at a website creation contest for junior and senior high school students.
To ensure service continuity and improve the operational infrastructure, JPRS enhanced its ability to restore
services more quickly, conducted test drills and optimized its personnel positioning, taking into account disasters
hitting Tokyo. It is also making efforts to improve the operational environment of the bases outside of Tokyo tokeep providing services. In addition, JPRS partnered up with eight ISPs of the electric power corporation groupto carry out a joint research and compile a report on the uninterrupted use of the Internet in the event of alarge-scale disaster. The report was published in 2017.
Going forward, JPRS will reinforce its facility to improve the fault tolerance of DNS and enhance the security ofits system in order to ensure continuity of service. JPRS will also continue to disseminate information on DNS
technology by issuing advisories on vulnerabilities and security alerts to support the stable operation of DNS.
As the registry of JP domain names, JPRS will continue its efforts to provide better and stable services.

03 Reference

About JPRSJPRS provides domain name services such as domain name management, administration anddistribution, and also performs domain name system (DNS) operations. In addition, JPRS is
engaged in research and development of various Internet technologies.

Domain Name Management and Administration
JPRS manages and administers domain names. In particular, JPRS plays an important role as the registry of JP
Domain Name, or domain names of Japan. You may have seen addresses for websites and emails such as“https://○○○.jp” and “△△△@○○○.jp.” JPRS manages and administers a part of these addresses, namely,
strings in the form of “○○○.jp.” Domain names are the key to accessing the Internet. JPRS is constantly improving
its services so that JP domain names will continue to assist the activities of all kinds of Internet users, including
companies, organizations, and individuals.

DNS Operation
DNS (domain name system) is a system for identifying computers connected to the Internet using domain names, so
it is sometimes referred to as the “phone book for the Internet.” If DNS were to fail, people would not be able toaccess websites or exchange emails using domain names. To prevent such a catastrophe, JPRS has established a
24/7 system to ensure stable operation of the “JP DNS” for managing JP domain names.

R&D of Internet Technologies and International Activities to Support the Internet
JPRS takes an active part in the research and development of advanced technologies to promptly respond tochanges in the Internet environment and social needs. Specifically, JPRS engages in standardization activities
through contributing to the internationalization of the identifiers used for protocols, devising methods for resolving
issues concerning DNS operations and submitting proposals to standardize registry technologies. JPRS actively
publishes the results of these activities and shares information at IETF and other meetings to contribute to the
network society.
