In the Long Grass on the Tamagawa

A bit of an oasis in Tokyo---at least the more urbanized part. If ya can't get out, the river is as good a place to go as any. On weekdays it isn't especially crowded, but on weekends and holidays things change quickly. Look for weather---cold, rain, very hot and humid days, snow, high winds all drive a lot of the more dainty indoors. Nights are nice too...
