Is there an English program or commentary during the event?

Yes, for the Tokyo Grand Sumo Tournaments only. At 4:00PM (30 minutes earlier on the final day of a tournament), an English radio broadcast begins in the venue. You can either bring your own small radio (iPods and many phones have them built in) with earphones, or you can rent one at the venue. If you bring your own radio, the frequency is FM 78.3MHz. Note that non-Japanese radios often can’t go as low as 78.3MHz, so you may have to set your radio’s region settings to Japan. The cost for rental is 200 yen, plus a 3,000 yen deposit that is refunded to you when you return the radio. You must return the radio by 6:15PM after the event ends.
