Those privy to contemporary Japanese ceramic art history might have heard of the Einin Tsubo Incident, which quite simply, rocked the very foundations of Japanese post-war society.
It did not simply destroy the credibility of many in the art world, the incident captivated the imaginations of the public, who gobbled up any bit of information/gossip they could obtain from the newspapers concerning the main actors in the incident, they being Kato Tokuro, his son (Okabe) Mineo and Koyama Fujio.
Usuke was on the committee for preserving culture by the Ministry of Education, and traveled all throughout Japan for exhibitions, traveled to Los Angeles for cultural promotion, and even has a piece in Czechoslovakia.
Nichiren Shu overseas propagation started with Renge Ajari Nichiji Shonin, one of the Six Senior Disciples of Nichiren Shonin, who on October 13, 1294 A.D. (Einin 2), on the thirteenth memorial day of his master, pledged to propagate his teachings overseas before the tomb of our Founder on Mt. Minobu.
On New Year's Day in the year 1295 A.D. (Einin 3), Nichiji Shonin left Matsuno in Suruga Province (Shizuoka Prefecture) and commenced the journey of an overseas missionary spreading "Namu Myoho Renge Kyo" throughout the various lands across the sea to fulfill his pledge.
Following the example of Nichiji Shonin's efforts, overseas missionaries continued, and especially during the modern age the movement gained momentum throughout Asia, Hawaii, North and South America.
