I went to an Urufuruzu concert (supporting acts Sambo Master and The Bawdies) in the Tokyo Sumo Hall today. Good fun and definitely a new experience for me as a concert venue. I didn't take photos during the concert as it wasn't allowed and I didn't wanna get kicked out, especially if it turned out to be a Sumo wrestler doing the kicking.
The toilets had a soap dispenser, tap and hand drier all in the sink. All were operated by sensors so no touching of taps, buttons etc. Would have been perfect except the hand drier was blowing cold air (and hand driers do little more than blow water from one part of your hand to another part even when they do expel hot air).
