Kazuo Takeda stated that Japanese rock would not be what it is today without Uchida, as he was one of the first to bring what was happening in the West in the mid-1960s back to Japan.

[1] He appeared in numerous films, such as Nagisa Ōshima's Merry Christmas, Mr. Lawrence, and won two best acting awards.

[4][5] Shocked after seeing Jimi Hendrix perform in London in 1967, Uchida returned home and wanted to introduce a similar sound to Japan.

After replacing all but one member and Uchida reverting to a producer/manager role himself, the group changed their name to Flower Travellin' Band and released another cover album, 1970's Anywhere, before relocating to Canada.

In addition to his solo career and Flower Travellin' Band, he worked with a large variety of musicians both domestic and international, and recorded with The Ventures and Frank Zappa in the mid-1970s.

[13] Uchida successfully underwent emergency eye surgery on May 31, 2005, for a blocked retinal artery, which would have led to blindness.

The police said that Uchida allegedly hit the 50-year-old woman after she tried ending their relationship in March and began sending her threatening letters.
