Roppongi Hills is a tall building in the Roppongi district in Tokyo.

The Mori tower seems like a world of its own as you can go for shopping, work, cinema, museum or stay overnight in a hotel.

From the top of the building you can enjoy a great view over Tokyo including the bay and the Tokyo Tower. The first possibility is indoor with a 360° view, but the best is the helicopter place on the very top. You can only access it if the weather is nice.

This picture was taken at Hasedera (海光山慈照院長谷寺) in Kamakura.

The Tokyo Dome is a big hall where different events take place (sports (especially baseball), concerts). The form of the hall is a bit like an egg.

Around the Dome is “Tokyo Dome City” - an amusement place with a ferris wheel, rollercoaster. At specific times you can visit a nice water perfomance with music at the heart of the amusement park (really really nice when it’s dark <3)
You can access Tokyo Dome via Suidobashi Station (水道橋駅) on the Chuo-line (中央線).
