Just as in the original Japanese version, the English version of the service allows users to check the details of the profiles and records of Makuuchi rikishi, and view all of their Torikumi videos. It allows you to receive the results of your favorite rikishis’ Torikumi via push notifications, vote for the Juryo and Makuuchi rikishi that showed the greatest effort, or in the period between Honbasho events only, watch featured videos of the matches of past Yokozunas.

During the Honbasho period, videos of the Makuuchi Torikomi will be made available daily through the app.
Free trial members may view one video per day reviewing the Torikumi of the day, and check the winner and other details. Torikumi videos are available for as far back as May, 2010, so you can watch Torikumi you may have missed, as well as popular past bouts, anytime on your SmartPhone.
