I'm in Tokyo right now until Sunday the 22nd with my wife.
We're melting. It's hot. Really hot. Crazy hot.
Any good suggestions for how to spend the day while beating the heat? Obviously, hanging out in malls has worked but even in the shade the parks are too hot for us Canadians.
We're on vacation, so we'd like something fun and relaxing: any pools with swim-up-bars? beach day-trips? Spas/baths (for couples and probably something cool, not hot).
We're in the shinjuku district, near the JR station - the closer to that, the better.
