Great place to get your work done, it's a library with nice interior space. 

This is my favorite go-to coffee shop in Tokyo. It's in a quiet and quaint space. I recommend trying their coffee and muffins. It's also right across a park and playground.

Izu-Oshima is a small island which takes about two and a half hours by speedboat from the center of Tokyo. It is 120km away, but still is "Tokyo". The island welcomes you with a distinctive landscape, having Mt.Mihara, a sacred volacano at the center. Travelers will fully realize how small they are facing the majestic landscape of Izu-Oshima.

A small cafe / restaurant in the heart of Aoyama. Does a really good homemade lemonade.

The Tsukiji Market ( Chuo-ku ) If you want to eat Sushi, you should go to Tsukiji not Ginza. This is the biggest market in the world. You can get better quality fish than anywhere else. The auction and cleaning of big fish are worth seeing. I aways come by the first train, take some photo, eat rice bowl dishes.
