Ryuho Okawa, the leader of the Japanese "Happy Science" cult who claimed to be able to communicate with the spirits of everyone from Jesus to Donald Trump, died Thursday aged 66, local media reported.
He was rushed to a hospital after collapsing at his home in Tokyo earlier this week, and his death was confirmed on Thursday, according to major media, including national broadcaster NHK and Jiji press agency.
The cause of the death was not immediately known, Fuji TV said.
Officials from the group could not be reached for immediate comment on the reported death.
Mr. Okawa was the singular leader and founder of the Happy Science group, which was started in 1986 and claims to have members in more than 168 countries.
The group believes in spiritual reincarnation and the construction of a global utopia, but faced public opposition for the personality cult around Mr. Okawa, including from his own son Hiroshi.
In 2020, he told the New York Times his father had "relentlessly lied to his followers."
"I believe what my father does is complete nonsense."
Among Japan's public, Mr. Okawa was perhaps best known for claiming to be able to channel the spirits of the rich and famous, as well as the books he authored based on what he said the spirits told him.
Recent publications include addresses from the spirits of Russian President Vladimir Putin on his decision to invade Ukraine, Jesus Christ on the pandemic and Queen frontman Freddie Mercury after the movie "Bohemian Rhapsody".
While Mr. Okawa stayed away from popular media, he was a constant presence in newspapers that carried advertisements for his latest books, as well as occasional movies and music.
He claimed to have had an epiphany at age 24, when he acquired an ability to communicate with spirits and realised his mission was "to lead humanity to happiness".
Mr. Okawa launched a political party in 2009 that advocates for a small government based on religious teaching, along with containing the rise of China and limiting the rights of the LGBTQ community.
The "Happy Realization" party has yet to win national seats, though its members have won local assembly seats.
Fringe religious groups have historically been able to operate in Japan with relatively few restrictions, but they have come under renewed scrutiny since the assassination of former prime minister Shinzo Abe.
His alleged assassin, Tetsuya Yamagami, reportedly targeted Abe over his links to the Unification Church.
In the wake of the killing, ties between the Church and senior politicians were revealed, and Japan's government passed new legislation intended to prevent religious groups from extracting massive donations from followers.
Mr. Okawa was born in 1956 in the rural Tokushima region. He graduated from the University of Tokyo, Japan's top academy, and joined a trading firm before quitting to start the cult.
