Wally Yamaguchi, better known as “Yamaguchi-san” in WWE, was the manager of a stable known as Kaientai (Dick Togo, Mens Teioh & Funaki) in 1998. It is unclear at the moment what the actual cause of death is, but it has been reported that Yamaguchi had been dealing with health problems since suffering a stroke in 2017.
WWE recently released the following statement on the death of Wally Yamaguchi:
WWE is saddened to learn that Wally Yamaguchi, Japanese wrestling fixture and former Kaientai manager, has passed away at the age of 60.

Although primarily known to the WWE Universe as the villainous Yamaguchi-San during the late 1990s, Yamaguchi was a key figure in Japanese sports-entertainment during the 1980s, editing “Gong” Magazine and working with various Japanese promotions as a referee and an agent.
In addition to appearing onscreen as Kaientai’s manager, Yamaguchi also worked with WWE as its Japanese liaison. His brother, Shun Yamaguchi, is a Japanese television announcer for WWE’s pay-per-view broadcasts.
WWE extends its condolences to Yamaguchi’s family, friends and fans.
