We took a day trip out to Kamakura one day that we were in tokyo. It is a little town right on the coast which ahs an amazing combination of surf-y vibe and historic zone. It is actually the first place in Japan that Buddism came to, and must have one of the highest consentrations of temples and monuments in Japan. It was beautiful and amazing, and only a 1h train ride out of the city.
Here is jenny and I getting all Zen with the giant Buddah.
