Usually, the airport. For most of us it would be a long swim.
Also, the Meguro Parasitological Museum (you may take this as a genuine suggestion, because I personally think it's awesome and they have great t-shirts in the shop - or as proof that asking for advice from random strangers on the internet may not go the way you hoped).
The page, or the museum? It was a few years ago that I went - I remember there's a shrine nearby where I killed a few minutes waiting for 10am to roll around and that it doesn't look much like a museum from the outside.
