Mostly Shinobazu Pond in Ueno, plus a cute building in Harajuku
19/08/2008: I was in Harajuku, I guess, and saw a cute building.
24/08/2008: Shinobazu Pond in Ueno Park has a section that, in summer, is entirely covered with blooming lotuses. There's also a Bentendou temple (with a shrine part too) on an island within the pond, which you can see from a distance, popping its head up over the lotuses. I only know these details because I googled 'Ueno pond temple' just now; at the time I was just taking photos of pretty things.
