This building seems to have quite bad luck. It has been built, destroyed and rebuilt several times through the history. Current version (who knows how long will last) is a very interesting mixture of traditional and modern Japanese architecture. I like the illumination of the main facade, especially on rainy days where you can see the lights reflecting in the rain.
Ginza is full luxury, gluttony and lust. But if you are not in those luxury stores, or expensive restaurants, there are still places to enjoy around here.
Gotokuji is a beautiful residential neighborhood located within Setagaya ward. Famous for holding one of the many Maneki Neko (lucky cat) temples, is a great place to explore. There are lots of great restaurants, temples and stores around that are worth the visit.
