Kamitool gathers roulette wheels, lotteries, sequential draws, amida-lottery animations, bingo-card generation, furigana, time calculation, and Japanese-era conversion in one tidy suite. It makes a clear privacy promise: names and entries stay in the browser, with no registration or installation required.

A Japanese-language collection of free browser tools for choosing, calculating, and preparing everyday things.
