Kateru is a Japanese verb with two distinct readings. In the Kyushu dialect it means to include someone or let them join a group. Written with the kanji 勝てる it means to be able to win or to be capable of winning. Either reading gives the name an active, purposeful quality that transfers cleanly into a Latin-alphabet brand.
