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

Introduction

The Internet is being used in increasingly broad and diverse areas of society as
technology advances. Along with that, the need for domain names and theimportance of the domain name system (DNS) are also being strengthened.
With this background, the number of JP domain names surpassed 1.57 million in
January 2020. Over 420,000 names are registered under “co.jp,” making it themost registered category in the Organizational Type JP Domain Name, the domainname space categorized by organizational type of registrants. 97% of
publicly-listed companies in Japan have already registered “co.jp” domain names.
JPRS is committed to its ongoing effort to improve JP domain name services,develop systems and carry out promotional activities to facilitate the use of JP
domain names and deliver greater value to users.
The domain name industry saw the number of domain names across TLDs
increase. On the other hand, various challenges have continued to threaten theInternet infrastructure, such as domain hijacking that exploits falsified DNS
configurations 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 todomain names and DNS as they arise. JPRS also actively contributes todiscussions of global issues and conveys relevant information to the communities
in Japan.
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 contributeto the development 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 its services including the management and administration of
JP domain names.
Reliability: establishing services with social credibility
Stability: operating and administering stable systems
Usability: providing user-friendly services
Fee Performance: setting reasonable service 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.

International Relations

1. Participation in ICANNICANN*1 is a private non-profit organization established in the
United States in 1998 to coordinate globally the resources
underpinning the Internet, such as domain names and IP
addresses.
Since its foundation, JPRS has been actively participating in
the organization of ICANN and various policy discussions andsupporting 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”

ICANN64

with ICANN and has since been entrusted by ICANN to serve
DVWKHUHJLVWU\RI-DSDQ·VFF7/'´MSµ
By participating in various organizations established within ICANN, as well as by giving presentations andinformation exchanges at various sessions, JPRS participates in policy development and implementation
planning to cope with issues facing ICANN and registries. Also, via ICANN, JPRS is sharing its experiencein JP registry operations with the global community, thereby contributing to the development of the Internet
as a whole.
ICANN holds three public meetings each year in different regions of the world to enable global stakeholders
to participate in person and discuss Internet resource management and related rules. In 2019, ICANN64
was held in Kobe City, Hyogo Prefecture in March, ICANN65 in Marrakech, Morocco in June and ICANN66
in Montreal, Canada in November. Before and during ICANN64, JPRS played a key role in the ICANN64
Local Host Committee and contributed to the success of the meeting.
With the participation of numerous parties interested in ccTLD and gTLD*3, ICANN has always functioned as
an important forum for information-sharing and discussion on issues on policies and governance concerning
domain name management. The ICANN Supporting Organizations (SOs) and the Advisory Committees(ACs) continued active discussions between different SOs/ACs to promote a better understanding of eachother in 2019. ICANN is serving as an important forum for SOs/ACs to exchange opinions on different topics
of interest, including Internet resources. The key topics in 2019 included the range of public data and theextent of accessibility to non-public data on WHOIS. The participants also discussed a broad range of

ccNSO*4 is one of the Supporting Organizations set up in ICANN to assist its activities. The role of ccNSO
as an alliance of ccTLD managers is to cooperate with the other Supporting Organizations in ICANN, form 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 a ccNSO Council member during the same time.
ccNSO held sessions to hear updates from the committees related to the operation of the IANA*5 function. It
also organized meetings to share information, ask and answer questions and discuss issues with theworking group on the process for retiring ccTLDs as well as the other working groups and committees within
ccNSO. Additionally, ccNSO participants had meetings to discuss topics of interest and trends unique to
ccTLD registries.
On the issue of how to handle country or territory names in TLDs, TLD-OPS* 6 , a community of ccTLD
managers including non-ccNSO members, exchanged knowledge on emergency response and compiled amanual for business continuity (play book). They actively shared information and expertise among
themselves by holding half-day workshops at the ICANN meetings.
At ICANN64 held in Kobe in March 2019, JPRS represented the local host and shared with ccNSO
members an update on JP Domain Name and its activities including the collaborative research using the“.jprs” gTLD for continuous Internet services in case of a large-scale disaster* 7. It also held a networking
event for exchanging opinions and interaction among ccNSO members and enhanced the visibility andunderstanding of JPRS and JP Domain Name.
JPRS gave a presentation on its efforts to detect DNSSEC validation failures in JP DNS servers andcontributed to the active discussions in the DNSSEC and Security Workshop as well as TechDay held forengineers during the ICANN66 Montreal Meeting in November 2019.

10 Registry Report(2) IDN Variant TLD Program
The IDN*8 Variant TLD Program is a project to develop Label Generation Rules (LGR) for the root zone. It
aims to establish rules for adding labels that include 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. The other Asian
language communities are also making progress.
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 IDN 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 of the
JGP. They are contributing their expertise gained through designing, providing and operating the Japanese JP
Domain Name services.
After mutual coordination among the Japanese, Chinese and Korean GPs, they respectively proposed the
LGRs for their own scripts to ICANN and moved onto separate discussions with the IP. These distinct
discussions with the IP concluded in the first half of 2017, as the consultation between the Chinese andKorean GPs took longer than expected. Based on the result of coordination between the Chinese and KoreanGPs, the JGP made a final adjustment with the IP and reached an agreement with it about the direction in
2018. In 2019, the JGP consulted with the Chinese and Korean GPs as well as the IP on how to handle
visually similar characters and then built a consensus about conducting a field test and reflecting its results to
the rules. The JGP also shared the development with the Japanese community at the ICANN Readout in
December 2019. The LGR for the Japanese community is expected to be complete in 2020.

Key Signing Key (KSK) should be carried out when necessary or every five years* 11 . 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 rolesof 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* 12. Yoshiro Yoneya of JPRS participated in thedesign team as a member.
The operation for the Root Zone KSK Rollover was launched in 2017. Signing with the new KSK began on
October 11, 2018, and then the old KSK was revoked during the period from January 11 to March 22 in
2019. This completed all the work steps for the Root Zone KSK Rollover affecting the configuration of theroot servers.
No major problem attributable to this particular Root Zone KSK Rollover was reported. The review of the
Rollover that was published by ICANN in March 2019*13 also described it as “an overwhelming success.” On
November 1, 2019, ICANN issued a proposal concerning how future Root Zone KSK Rollover should be
conducted*14.
Currently, a review of the performance and development of the process for subsequent Rollover are
underway. The operational plan for the next Rollover will also be formulated.

To tackle the problem of domain name abuse, JPRS stepped up its information provisions andeducational activities for proper domain name management and operation. It also improved its work process
and set up a point of contact to receive domain name abuse reports.
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. Especially, JPRS continued to contribute to ICANN by engaging in various activities and leading
discussions. It also played a key role in the organization of the ICANN64 Meeting held in Kobe in March 2019as a member of the ICANN64 Local Host Committee.
The year 2019 continued to see a number of incidents threatening the stable operation of the Internet, such as

response. JPRS collaborated with other relevant organizations and responded to these problems by alertingthe community.
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 ten years in a row, with the number of copies
distributed in the last ten years exceeding 290,000. It also produced a poster to help students learn ccTLDs ina fun way and distributed copies for free to educational institutions across Japan. Moreover, JPRS continued
to provide domain names free of charge at the website creation contest for junior and senior high school
students to support children who will lead the next generation.

24 Registry Report

Going forward, JPRS will continue to improve its services, increase the security and robustness of the system
and reinforce its facility to enhance robustness against faults and attacks. It will also strive to ensure fasterrecovery and continuity of the service through disaster drills. Moreover, JPRS will 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.

38 Registry Report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.
