NBA Rakuten is a free Android application developed by Rakuten Inc. that provides access to over 1200 games, including the NBA Finals, playoffs, summer leagues, and pre-season matches. You can watch all the games live without any cuts, and the videos are uploaded immediately after the game ends. NBA Rakuten also offers a wide range of video archives such as game highlights, best plays, and original Rakuten programs that convey the charm of NBA with guests. Plus, the app provides the latest NBA news and a wealth of stats (play results data) that are updated daily. You can interact with other users through live chat and forums, and the app supports viewing on TV devices such as Chromecast.

However, some of the videos and features require a paid subscription, and the number of games you can watch depends on the plan. Moreover, all videos are limited to viewing in Japan.
