1. Mid- to Long-term Research Objectives and Strategies Based on the Center’sResults during Funded Period

Describe new challenges in the Center’s research objectives and plans after the funding period ends. If major adjustments will be madein the Center’s operation, such as newly set research themes/objectives or a change in the director, describe the strategic background to
the adjustments.

The mission of the Kavli IPMU is to discover fundamental laws of nature and to use them to address
the questions about the Universe; how it was born, how it evolved, and what the future will be. Our longterm objectives are to solve these problems by integrated efforts of mathematicians, physicists andastronomers. Immediately after H. Ooguri became the Director in the fall of 2018, he initiated the Long
Term Strategic Planning Exercise of the Kavli IPMU. It identified the following three areas as theinstitutional priorities in experimental physics and observational astronomy:•
CMB Projects•
Kamioka Projects•
Survey Astronomy Projects.
Each of these projects involves multiple faculty members of the Kavli IPMU, and a large fraction of ourresources will be invested in them. All these projects are consistent with Kavli IPMU’s mission. Cosmology
and neutrino physics are making significant progress and there are also opportunities for synergies among
these projects. We expect that these investments will bear fruits over the next five to ten years, and it isimportant to ensure their successes. In addition to these priority areas, we will also support projects
conducted by single PI’s as well as theoretical research.
1.1 CMB Projects
The Kavli IPMU is participating in POLARBEAR/Simons Array and the Simons Observatory. We areplaying a major role in the Simons Observatory upgrade. The experiences we have gained in this project
are important for us to take the leadership in the Japanese project, LiteBIRD.
ISAS (the science division of JAXA) has approved the launch of the LiteBIRD satellite, currently
scheduled in November 2029. The Kavli IPMU is a lead institution for its Master Plan 2020 proposal to the
Science Council of Japan and is expected to contribute to the project with development of polarization
modulators and hosing of the data analysis center.
Currently, there are three faculty members working on CMB projects. Assuming that LiteBIRD will
receive a final approval by JAXA and is fully funded both for the polarization modulator development andthe data analysis center, in a steady state of the project, we plan to keep the current size of faculty on
CMB projects.
1.2 Kamioka Projects
The Kavli IPMU is involved in several projects at the Kamioka Observatory.
SK-Gd: This project is a fulfillment of the idea of Kavli IPMU PI M. Vagins and his collaborator J. Beacom.
Since 2020, the gadolinium is being added Super-Kamiokande, and the sensitivity is expected to increase
substantially in the coming years. It will make it possible to detect signals of supernova relic neutrinos andof anti-neutrino spectrum from nuclear reactors.
T2K: Full physics operation started in 2010, with the best constraint on δ CP by summer 2017. T2K is
expected to become an important partner of the Hyper-Kamiokande project described below. A couple ofour faculty members are involved in this project.

Hyper-Kamiokande: The construction has started and is in steady progress despite the COVID-19
pandemic.
1.3 Survey Astronomy
Hyper Suprime-Cam (HSC) and Prime Focus Spectrograph (PFS) are flagship projects of the Kavli IPMU.
Currently, there are 5 full-time faculty members, 7 affiliates, 10 postdocs, 5 students working on them. The
Kavli IPMU has played critical roles in funding and leadership of these projects. HSC has already had great
success with its early science results, in particular with the weak lensing survey, and more results are
expected with full data set. PFS will play a complementary role with highly multiplexed, deep, wide redshift
survey. The instruments are being assembled in Hawaii.
To make the most of HSC and PFS, close collaborations with other survey projects worldwide are
essential. Rubin Observatory (LSST) will be the main survey project for the coming decade. It is a naturalsynergistic extension of HSC and PFS, and there are opportunities to make an impact with our experience
with these projects. Coordinating with NAOJ, we are negotiating with the Rubin Observatory on in-kind
contributions to the project, which will include providing substantial computer time for data analysis.
WFIRST is expected to be launched in October 2025. Subaru is supposed to contribute 100 nights. Data
analysis support, in particular interface to data is going to be important.
1.4. Single PI Projects
There are several projects conducted by single PI’s. Scientifically, they are all excellent projects andwe will continue to encourage such activities:
Belle II: This is a major national project following the successful Belle experiment, which verified thetheory of Kobayashi and Maskawa, leading to their Nobel Prizes. The Kavli IPMU group successfullycompleted the semiconductor detector production and delivery in 2018, and the experiment started in
March 2019. Subsequently, our group has made a successful transition to data analysis.
XENON-nT: The Kavli IPMU is making an impact on the project with its contribution of the gadolinium
technology from Kamioka, eliminating the need for the problematic liquid scintillator.
Medical Applications of Gamma-Ray Imaging: It is important to explore opportunities like this one
to make our basic science research useful to the society. Currently, the project is funded by grants for T.
Takahashi, with a laboratory at the National Cancer Center. It provides opportunities for us to makesocietal impacts.
1.5. Theoretical Research
Project-style research is not suited to theoretical studies. Nevertheless, there are a few important topics
about which we expect to make significant contributions.
Mathematics and Theoretical Physics: Collaborations between our mathematicians and theoreticalphysicists have been very successful and have yielded many noteworthy results until today. We will
maintain such interactions. Our challenge in the coming decade is to expand the frontiers in algebraic
geometry toward other areas in mathematics and theoretical physics.
One of the important issues is to study the categorical aspects of quantum field theories (QFT). A few
years ago, the concept of perverse schobers was proposed by a Kavli IPMU researcher (M. Kapranov),
which are categorical analogs of perverse sheaves. The work up to now indicates that perverse schobers
provide, among other things, a mathematical framework for the study of 2 dimensional QFT in the infrared
limit (the Algebra of the Infrared of Gaiotto-Moore-Witten) as well as for induction-restriction formalismof Representation Theory. Developing a solid mathematical foundation of this theory is a challenge.
Another related issue is the study of moduli spaces of coherent sheaves on algebraic varieties. Thosesheaves also appear in supersymmetric gauge theories in theoretical physics. Many quantum field theoretic
quantities, such as partition functions, correlation functions, are expressed as integrals over moduli spaces.
Even more, finer objects, such as Hilbert spaces in quantum physics, could be related to moduli spaces.
Thus, studies from the mathematical side will give tools to compute physical quantities. On the other hand,research in physics will provide different ways to look at moduli spaces, and lead to the existence ofstructures that are unexpected in mathematical studies. We hope that our planned studies on moduli
spaces may give new insights into other fields of mathematics, such as representation theory, number
theory, and so on.

Kavli IPMU

Astrophysics, Cosmology and Particle Physics: In the areas of astrophysics and particle physics,
there is an important unsolved issue, i.e., the nature of dark matter and dark energy.
With the planned world-leading projects mentioned above at hand, our challenges are to develop an
efficient analysis method that can deal with the big data delivered by those projects. The planned surveys
are aimed at collecting images of billions of galaxies and stars. Data to be delivered by those surveys
typically exceed tens of petabytes. Real-time analysis of the sheer volume of data is a real challenge. It
necessitates us to develop efficient data analysis methods using machine learning. The expected scientificoutputs and the potential of unexpected discovery heavily rely on how well astronomical/cosmologicalinformation can be extracted from the large data set. We will make a concerted effort with astronomers,
physicists, mathematicians, and computer scientists to develop such a method to develop a “machine”
that automates data analysis and scientific discovery from the large observational programs.
As for theory, diverse studies on dark matter have been performed at the Kavli IPMU for various
candidates ranging from ultralight to macroscopic ones. For example, Primordial Black Holes (PBH) as a
macroscopic candidate, Electro-Weakly Interacting Massive Particle (EWIMP) as a heavy particle candidate,Weakly Interacting Massive Particle (WIMP) as a typical particle candidate, sterile neutrino as a nonthermal light candidate, Strongly Interacting Massive Particle (SIMP) as a thermal light candidate, dark
photon as a very light particle candidate, axion as an ultralight (wave-like) candidate. Through thesestudies, we proposed concrete models, found new mechanisms on dark matter processes, suggested
experimental methods to test the candidates, and contributed to dark matter search projects by showing
the nature of each candidate. We will keep developing such theoretical models, in particular, throughvarious international and interdisciplinary collaborations with other fields, i.e. astrophysical observations(HSC, PFS) for pBH/EWIMP/WIMP/SIMP, TeV gamma-ray observations (CTA) for EWIMP/WIMP, MeV
gamma-ray observations (COSI) for WIMP/sterile neutrino/SIMP, underground experiments (XENON) for
EWIMP/WIMP, chemical synthesis (new direct dark matter detection) for SIMP/dark photon, and precision
physics (Atomic clock, GW) for axion, hadron collider experiments (HL-LHC) for EWIMP/WIMP, lepton
collider experiments (Belle II, ILC) for WIMP, SIMP, and so on.
Quantum Information Theory: The Kavli IPMU is a member of the Trans-Scale Quantum Science
Institute, a crosscutting research platform for quantum science including cosmology, particle physics,
condensed matter physics, quantum information and mathematics at the University of Tokyo. Theoreticalphysicists at the Kavli IPMU are involved in applications of ideas and techniques of quantum information
theory to advance our understanding of quantum gravity. We are also expecting that insight gained inquantum gravity theory can be useful in quantum computers and quantum cryptography. In addition tofaculty members working in this area, we are supporting research activities at the interface of quantum
information and quantum gravity with postdocs appointments and conferences.

2. Management System of the Research Organization

2-1. Describe the Center’s Research Organizational Management System that will
Execute the Research Strategy and Plan Described above.
・ In Appendix 1-1, list the PIs who will ensure that the Center’s project is sustained and advanced after the funding period ends.
・ In Appendix 1-2, enter the number of Center personnel (researchers, research-support staff, and administrative staff) in FY 2022
・ In Appendix 2, diagram the Center’s organizational management system.

To secure success in the above research objectives, human resources are essential. We will maintainour high standard in recruiting new faculty members and hiring postdocs from all over the world. In 2021,
the Kavli IPMU has launched the diversity initiative to promote the diversity and inclusion in our instituteand spread successful practices within the University of Tokyo and throughout Japan.
A few PIs are assigned to each of the main objectives 1.1, 1.2 and 1.3, so that the scopes of research
will be as wide and deep as possible. To further enhance international collaborations, the Kavli IPMU istaking part in collaborative agreements with IN2P3/CNRS, France, in the areas of CMB, neutrino physics
and survey astronomy, together with ICRR, University of Tokyo. For the single PI projects as well as
theoretical projects, each PI or faculty member will tackle their respective objectives. To encourage mutualinteractions and multidisciplinary collaborations, we will keep our tradition of daily teatime at 3 pm.
Currently, some of our PIs are faculty members of the Kavli IPMU and others are associated with otherinstitutions. The job descriptions in comparison to those of tenured faculty members (full and associate
professors) have not been well-defined. We are currently reviewing both the PI system and the facultysystem and will come up with a coherent personnel system and document them.

The University of Tokyo - 3

Kavli IPMU

Similarly, we are also working on a personnel manual that describes rules governing faculty recruiting
and promotions. Documenting these rules is important to ensure that everyone is treated fairly andconsistently. This is particularly important in promoting the diversity and inclusion and in attracting talented
researchers from all over the world.
Our supporting and administrative staffs are also among the most efficient in the world. We will maintaintheir high quality by properly assigning their duties and clearly defining their responsibilities.
Currently, the Kavli IPMU is managed with the strong leadership of the Director, and the steeringcommittee chaired by the Director is its decision-making body on important matters such as faculty hiringand promotion. This top-down management structure allows timely decisions on recruitments, retentions,and resource allocations. The organization remains flat with no “departments” within the institute, and the
directorate is always open to new initiatives from the individual faculty members. We intend to maintainthis administrative structure in coming years.

2-2. Initiatives and Plans that will Impel System Reforms

・Describe the Center’s action plan that embodies the basic policies of the University Reform Plan, and the Center’s plan and strategies
that lead to host institution reforms either directly or via ripple effects (also to other institutions, if applicable). Describe also theCenter’s strategies for fostering and securing the next generation of researchers (e.g., introduction of tenure tracks), and the system
reform for enhancing the Center’s organizational management, such as the implementation/verification PDCA system.
・Describe your plan for sustaining and enhancing the WPI brand.

The Kavli IPMU has been successful in implementing system reforms. They include:• establishing the environment to concentrate the research• split appointments with institutes outside Japan• merit-based salary system• global standard for the hiring system• “nenpo” system
The successful reforms of the system and organization within the Kavli IPMU should not stay confinedwithin our Institute. Already, many of our accomplishments are taken up by the University administration.
We take the role of an evangelist to make these reforms permeate the system to boost the overall
competitiveness of research in Japan. One of the examples we have achieved to spread these reforms canbe seen in the Administrative Director’s contribution to Tokushima University on the program establishedby the Cabinet Office project “Promotion of Regional Industries and Universities”. He gave a lecture to the
President and board members of Tokushima University on the detailed successful experience of the WPI
program at the Kavli IPMU. He has been assigned as a member of the External Evaluation Committee ofthe newly established laboratory at the university.
As an important aspect of fostering and securing the next generation of researchers, recently we haveestablished a new tenure track system. A tenure track assistant professor is hired for the initial sevenyears, and through the process of mid-term review and the following final review, the candidate can be atenured associate professor. Also, we are planning to form a standing committee to search for talented
young researchers, especially for female and minority researchers. We defined the Kavli IPMU code of
conduct to guarantee the diversity initiative research environment and it was developed to the University’scode of conduct later.
Regarding the education of young people including undergraduate students, a successful program
between Oxford University and the Kavli IPMU since 2015 has been producing a couple of PhDs every
year. So far, we have accepted nine students, and five have defended their Ph.D. theses. In addition tothat, the excellent graduate student program WISE is accepted by MEXT and the faculty members in Kavli
IPMU can officially approach to foster students.
The Kavli IPMU is now recognized as the one of the prominent WPI institutes from over the world. We
are obliged to keep this WPI brand even after the WPI full support is terminated. So, what is the WPI
brand? We recall the four missions of the WPI: science, fusion, globalization and system reform. For
science and fusion, we will enter the fruitful season of the world top class projects soon and high visibility
can be achieved through those results. We will make further effort to keep the present world top levelresearchers stay inside the institute by guaranteeing the excellent research environment as it is.
Fortunately, we have been keeping around 50% fraction of foreign researchers for many years. Thisimplies that our institute is comfortable for many foreign researchers to accomplish their advanced
research. This is the results of system reform done under the strong motivation as the WPI institute for
14 years. We will always conscious of what we have done and how to challenge for the next step to reacha much higher level.

3. Plan for Promoting the International Circulation of World’s Best Brains

Describe your policy and concrete plan for promoting the international circulation of the world’s best brains, which is an importantfunction of the WPI Academy.

Our program to keep requiring our postdocs to spend at least a month up to three months per year
visiting institutions abroad has been done successfully for a long time. By this young researchers’
activities, the name of Kavli IPMU spread all over the world in this decade and a half. Also we invited many
world-top researchers as well as young researchers with high potential. In addition, we established named
visiting professorships and fellowships. These efforts have been the key to achieve our international
composition with almost half of the researchers being non-Japanese nationals. Every year, about half of
800-1000 visiting researchers are from abroad. The international solicitation for postdoc plays the key andimportant role for the young excellent brain circulation. About 700 applicants annually compete for about
12 Kavli IPMU postdoc positions. The short-listed candidates are excellent, and about 30 % of full number
of offers are normally accepted. After three years postdoc research, about a half of “graduate” postdoc
normally found tenure, or tenure-track faculty positions at universities, research organizations. Afterleaving the institution, many active researchers are assigned as affiliate members of the Kavli IPMU. We
support traveling and staying accommodations to make it easy to visit us. New collaborative research
between inside researcher and affiliate member is expected to be commenced in such occasion.

4. Center’s Position within Host Institution and Measures to Provide It with
Resources
Describe the Center’s future plans with regard to the following points after the funding period ends.

4-1. From a Mid- to Long-term Perspective, the Position of the Center within the
Organization of the Host Institution

Describe where the Center will be placed within the host institution’s overall organizational strategy under the leadership of theinstitution’s head.
・ In Appendix 3, diagram the Center’s position within the organization of the host institution, and describe that positioning using
excerpts from the institution’s mid- to long-term plan. If the plan has not been established yet, describe the consideration being given
to the Center’s positioning.

The University of Tokyo recognizes that the Kavli IPMU is the flagship of the University, and thesuccessive Presidents of the University have expressed their commitment to the Kavli IPMU at many WPI
occasions, such as meetings of the Program Committee, Site visits, and follow-up visits.
In March 2021, UTIAS (University of Tokyo Institute for Advanced Studies) approved that Kavli IPMU
to stay continued as a research organization within UTIAS. The criteria of these qualifications are: theinstitute should be evaluated as an excellent international research initiative, world top-level researches
are active there, enough running budget is secured, and enough globalization of research environmenthas been achieved.
In April 2021, new President T. Fujii pointed out three important strategies in his inaugural message.
Those are: conversation in person, diversity and inclusion, and visible and centripetal UTokyo.
In his address,“Diversity and inclusion are fundamental not only in the creation of academic knowledge, but also tohuman resource development, university management and partnerships with society…. In addition, we
will gather outstanding people with diverse backgrounds from around the world as faculty, staff andstudents, and create a place where they can thrive”.
“By realizing a digital campus that promotes digital innovation throughout education, research andadministration, we aim to improve the quality of faculty and staff members' time and work, and make
UTokyo a place of learning where people from around the world will want to come and join”.
The President is now preparing the institution’s mid-to-long-term plan which will match with the FourthTerm Mid-term Target.

4-2. Host Institution’s Action Plan for Sustaining and Advancing the Center as a World
Premier International Research Center (e.g., Positioning, Financial Resources)
・ In Appendix4, describe the host institution’s resource allocation plans for the Center, including the allocation of posts (in both its
research and administrative divisions).

In March 2021, the University of Tokyo approved our proposal to place the university funding for the
Kavli IPMU in the core expenses category, at about 1 billion yen per year. Being part of the core expenses
The University of Tokyo - 5

Kavli IPMU

category means that the funding is permanent. The Kavli IPMU is also keeping its status as a researchorganization inside UTIAS guaranteed its special managing system. These actions reflect University’scommitment to sustain the Kavli IPMU as a permanent institute, both in terms of finances andadministrative arrangements.
The Kavli IPMU has already secured 26 permanent positions for the core of faculty to guarantee
excellent activities of the Kavli IPMU as it is. Most positions are assigned to core faculty. The University
secured also 9 UTokyo permanent administrative staff. In addition, the university has decided that termed
administrative staff should be hired as permanent positions including bilingual staff. It means that the
many supporting staff for the foreign researchers can stay in the Kavli IPMU. The loan for the main building
has already completed and three rooms at the second complex building are free for us. UTIAS is an
outstanding support system allowing the Kavli IPMU to operate as an incubator of systems reform within
the University.
In 2020, the Kavli Foundation decided to increase the Kavli IPMU endowment by $10 million,
guaranteeing a stable source of discretionary research funding. The Kavli Foundation has also committed
to provide matching fund up to $2 million to help fund raising of UTokyo for more support for the Kavli
IPMU. These actions reflect the trust and appreciation of the Kavli Foundation on the Kavli IPMU regarding
its high level of research activities and the stewardship of the endowment.
The grant from Hamamatsu Photonics has been renewed for 5 years from 2019 to 2023.
The University of Tokyo is committed to maintain the excellent research environment for the Kavli IPMU
to function as a world premier leading institute.
