Reiyūkai (霊友会 Spiritual-Friendship-Association), or Reiyūkai Shakaden, is a Japanese Buddhist new religious movement founded in 1925 by Kakutarō Kubo (1892-1944) and Kimi Kotani (1901-1971). It is a lay organization (there are no priests) associated with Nichiren Buddhism.
Reiyūkai considers itself the grandfather of lay-based new religions devoted to the Lotus Sutra and ancestor veneration.
Reiyūkai membership currently stands at 5.14 million members, with the majority living in Japan.
In 1920s, during the crisis after the 1923 Great Kantō earthquake and the following economic depression, Kakutaro Kubo begins formulating his philosophy for what is now Reiyūkai. He compilies and published The Blue Sutra (a collection of texts from the Threefold Lotus Sutra), used by members for recitation practice.
In 1930, Reiyūkai was inaugurated, Kakutaro Kubo became Chairman of the Board of Directors and Kimi Kotani becomes President. In 1937, headquarters were established the Iikura area, Tokyo. In 1954, the Reiyūkai Youth Group was inaugurated.
In 1971 Kimi Kotani died and Tsugunari Kubo became president. The next year, a Reiyūkai Centre was established in the United States. It was followed by centers in Brazil and Canada (1975); the Philippines (1976); Mexico, Italy, and Taiwan (1977); United Kingdom (1978, closed as of March 1998); Peru, Thailand, and France (1979); India, Nepal, and Paraguay (1983); Spain (1984); Korea (1988); Bolivia (1996) and Sri Lanka (1999). In 1980, the Reiyūkai’s Inner Self Development campaign began.
In 1985, representatives from 14 countries participated in a Youth Speech Festival in commemoration of United Nations International Youth Year. Since then, national festivals are held annually throughout the world and international festivals are held in the Asian, American and European regions on a regular basis.
In 1990, the Sixth International Youth Year Speech Festival was held in Osaka, Japan, as part of the International Garden and Greenery Expo ’90. Representatives from 17 countries attended.
In 1992, Reiyūkai International Operation for Cambodian Relief (RIOCR) opened its office in Cambodia. The next year, Reiyūkai International Committee was inaugurated.
In 1994, the Tenth International Youth Year Speech Festival was held in Kathmandu, Nepal. In 1996 Tsugunari Kubo resigned as President of Reiyūkai and Yae Hamaguchi became her successor. The Reiyūkai-sponsored Lumbini International Research Institute (LIRI) was inaugurated in Nepal and the International College for Advance Buddhist Studies (ICABS) was established in Tokyo. The First Reiyūkai Supervisory Council was inaugurated.
In 1999, Reiyūkai established Japanese and English homepages on the Internet. In 2000, the 4th Reiyūkai International Conference was held in Tokyo. Yae Hamaguchi died, and Ichitaro Ohgata succeeded as President, Yushun Masunaga and Hiromichi Hirakawa as Vice Presidents.
In August 2004, the Reiyūkai sponsored, together with Japan International Cooperation Agency (JICA), the UN World Food Program and Nikkei newspaper, the World Youth Peace Summit (WYPS) Japan conference, as a direct outcome of the Asia-Pacific Regional Conference. It was held at the United Nations University in Tokyo. Over 400 youth delegates engaged in lively discussion and decided to mark the date, August 5th, as International Youth Peace Day and will organize an event on that day each year. The summit was broadcast by the Japanese national broadcaster, NHK, on its BS Forum.
From April 8, 2013, Masaharu Sueyoshi is currently the Reiyūkai International President.
Reiyukai France is member of the European Buddhist Union (EBU) since 1997.
"Shakaden" in the name Reiyūkai Shakaden means that this organization lays extra emphasis on the veneration of Shakyamuni Buddha, the founder of Buddhism. The Shakaden is an architectural complex that serves as a meeting place and social center for Reiyūkai members in the local community. In Japanese, "Shakaden" means the "House of Shakyamuni." It is a place where anyone can seek to further practice the teachings of Shakyamuni Buddha. It consists of the Main Hall, the Plaza, the Kotani Hall, various conference rooms, a cafeteria, a child care room, and a nurse's office. After four years of construction, the Shakaden was completed in 1975. Shakaden is a 3 minute walk from Kamiyacho subway stop, Hibiya Line.
It is on the side of Togasa Mountain in the center of the Amagi Mountain Range on the Izu Peninsula; its building was strongly supported by Kimi Kotani, as a meeting point for young people, for an immersive visit in a natural environment, where to exchange experiences with other members. It was completed in 1964. It is dedicated to Miroku (弥勒), that is Maitreya, a future Buddha, whose apparition is waited by all Buddhists.
Reiyukai is a pacifist movement. For Reiyukai, peace can be achieved through the promotion of one’s personal development for the benefit of all humanity.
The Inner Trip Ideologue Research Center (IIC) was founded to raise awareness about the value and importance of engaging people within society, fulfilling one’s civic responsibilities, and participating in the political process. As an opportunity to deepen the knowledge of politics and to transmit the voices of people, the IIC organizes various lectures and seminars in different locations within Japan inviting politicians as guest speakers. Also, the IIC publishes a monthly magazine providing a space for politicians to present their political viewpoints. Former Tokyo governor Shintaro Ishihara is a believer and writes in Reiyūkai publications.
Ms Claudine Shinoda, of Reiyukai France, has been president of EBU for 3 years and vice-president for 6 years. In this role, she was a speaker in various international meetings:
