Playing online
Japanese Mahjong can be played on various online sites and clients.
Tenhou.net
Tenhou.net is one of the most popular sites to play the game, and one of the most established. The English support is poor without a translation add-on (Chrome, Firefox), and the UI is not as up-to-date as many other websites.
Mahjong Soul
Mahjong Soul is another one of the most popular sites. It has a much newer client than Tenhou.net, with native English support. It has "anime" aesthetics. The game features gacha mechanics to obtain characters and other cosmetics.
Riichi City
Riichi City is an app similar to Mahjong Soul. Like Majsoul, it has an anime aesthetic and gacha mechanics. The playerbase is much smaller than either Majsoul or tenhou.net.

Single-player games
The ever-popular Bamboo Game is a spinoff of Japanese Mahjong, played against a single computer opponent using only the 36 Souzu tiles. All hands are at least Chinitsu.
