The first meeting of the Hyper-Kamiokande Experiment Financial Forum (HKFF) in which the foreign agency representatives gathered to engage in discussions with the host organizations and the project members, was held at Kojima Hall, Hongo Campus, The University of Tokyo on January 11th ,2019.
About 50 participants atend the first meeting of HKFF
Hyper-Kamiokande (HK) is a new world-leading international scientific research project and aiming to start its operation in the second half of the 2020s. The HK detector is planned to have eight times larger fiducial mass than its predecessor detector, Super-Kamiokande, and it is equipped with newly developed high-sensitivity photosensors. The aim of HK is to elucidate the Grand Unified Theory and the history of the evolution of the universe through an investigation of proton decay and CP violation (the difference between neutrinos and antineutrinos), together with the observation of neutrinos from supernova explosions.
In October 2017, the Next-Generation Neutrino Science Organization (NNSO) was established in the University of Tokyo by the Institute for Cosmic Ray Research (ICRR), the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), and the School of Science to cooperate in pioneering the future of neutrino physics programs through the development of neutrino research techniques and detector technologies. Professor Takaaki Kajita, the director of NNSO, invited the foreign agency representatives and researchers from 14 countries (Armenia, Brazil, Canada, France, Italy, South Korea, Poland, Russia, Spain, Sweden, Switzerland, UK, USA and Japan) and about 50 people gathered to hold discussions.

In the meeting, Prof. Kajita made an opening address saying, “The forum was established to offer a place for the agencies to find out the details of the Hyper-Kamiokande project including its goals, timelines and the organizational structure, and to share information on interests and constrains of each country and region. We’d like have discussions to identify the necessary tasks to make the international collaboration more solid.” The President of the University of Tokyo, Makoto Gonokami said, “Of course, this project cannot be realized by the University of Tokyo alone. Cooperation with international partners, as well as the High Energy Accelerator Research Organization (KEK) and other institutes in Japan, is indispensable. We look forward to closely working with you in the future, and hope that this meeting will be the first step towards our fruitful collaboration and the success of realizing this exciting project.”
Also, Mr. Keisuke Isogai, the director-general of the Research Promotion Bureau in the Ministry of Education, Culture, Sports, Science and Technology (MEXT), Keisuke Isogai commented, “We at MEXT intend to do our utmost to realize the project as soon as possible in light of the project’s extraordinary scientific significance.”

The forum looks forward to reviewing progress again towards realizing the project.
On the next day, January 12th, about 25 participants made a visit to the Super-Kamiokande detector in Hida City, Gifu Prefecture, whose tank is almost full of water after the refurbishment work.
