More anime character name references. Featuring the Rockets.
Yamato (Cassidy) was the name of a battleship used during World War II. There's a similar type of ship named the Musashi. Cassidy is named after the Wild West outlaw Butch Cassidy, following the pattern of Jessie and James.
Kosaburou (Butch) means "third son," while Kojirou means "second son." Butch is named after the Wild West outlaw Butch Cassidy, following the pattern of Jessie and James.
Mondo (Jessie and James' off screen helper and Ditto trainer) is named after Mondo Nakamura, the hero of "Hissatsu Shigotonin," a live-action movie series released in Japan during the mid-eighties. Mondo was played by Makoto Fujita.
Miyamoto (Musashi's mother) is probably a continuition of the same legendary samurai that her daughter is named after, Musashi Miyamoto (1584-1645). Or for a subtle nod, to Shigeru Miyamoto's surname and his reputation for being the best, just as our Miyamoto was the best agent for Team Rocket in her day.
Domino, no doubt named for her manipulative outlook on life, as with the game.
On'na-Boss (Giovanni's mother and founder of the Rockets), a literal Japanese wording, On'na means woman, so her name translates to "Woman Boss"
Jinjii (Wendy), another Japanese wording. Jinji is the Japanese word for "personal concerns," fitting for a character who is mad at Musashi for such a trivial reason.
Bashou is a famous 13th century haiku poet, fitting given our Bashou is just as intellectual.
