Time Out says
Tokyo Midtown hosts this grand-scale outdoor skating rink, which can accommodate about 200 skaters and gets lit up beautifully by lights lining the entire perimeter from 5pm until 10pm every day. The best thing is that you don’t even need to take off your skates to take a break in the heated ‘rest area’. The entrance fee includes skate rental, but note that wearing gloves (not included) is mandatory. Helmets can be borrowed for free.
