I've started looking for, and reading, blogs of people who have recently moved to Japan. This is far more interesting than reading blogs of people who have been here for a long time, especially if the bloggers live in Tokyo. Tokyo is a wonderful place, but it does tend to fuck you up, in that it weakens your character and makes you lazy. Reading blogs written by people who have just got here is very refreshing, and has given me a much-needed energy boost.
A couple of great blogs I've found are "Hello Sandwich" and "The Get-Go Tokyo".
Hello Sandwich is written by Ebony, who lives in Shimokitazawa. The blog deals mainly with Japanese design, and is packed with great photos of cool things and places.
The Get-Go Tokyo is written by Gaby, a young British woman who is a pre-school teacher in Tokyo. Full of great insights into getting your shit together in Japan.
