Some weekday admission numbers from Japan. These are from the TOHO chain, the largest theater chain in Japan which accounts for 20% of market share.
Tue:21,531
Wed:43,281 (Ladies Day, Discounted ticket price for women)
Thu: 26,909
Estimates in dollars from people who know the Japanese market much better than I do...
Mon- $1.3m
Tues- $1.5m
Wed- $2.4m
Thurs- $1.7m (estimate)
From what I'm hearing, these weekday numbers are huge and Frozen could very well have no drop, or even increase from last Fri-Sun numbers.
Frozen got some excellent free advertising too, TOHO has opening a brand new theater opening tomorrow, but the Royal family went to a screening of Frozen there yesterday and now it's virtually sold out. Interestingly this theater is only showing Frozen 3D (I can't seem to find how many screens it has).
