Setagaya (世田谷) is in western Tokyo, and is the largest of the city's 23 wards.
Setagaya has a reputation as an upscale residential district, and features many areas of greenery. The funky shopping and nightlife area of Shimokitazawa (下北沢), popular with students and young adults, is also located in Setagaya. The Sangenjaya (三軒茶屋) shopping district is also in Setagaya.
Shimokitazawa is on the Odakyu and Keio Inokashira train lines, just a quick hop from Shinjuku and Shibuya respectively. Most of the action is around the South Exit.
Sangenjaya is on the Tokyu Den-en-Toshi train line from Shibuya.
Komazawa-Daigaku is on the Tokyu Den-en-Toshi train line and near to Sangenjaya.
There are Komazawa University that takes a few minutes from a station.
The main train lines serving Setagaya are the Odakyu from Shinjuku to Odawara and the Keio Inokashira, Tokyu Toyoko, and Tokyu Denentoshi, all originating in Shibuya. Since all of these lines run generally westward from hubs on the Yamanote line, it can be somewhat difficult to travel north-south without going in to a hub and back out.
The Tokyu Setagaya line between Sangenjaya and Shimo-takaido is one of only two remaining streetcar lines in Tokyo.
- Carrot Tower (キャロットタワー). Located in Sangenjaya, this is the tallest building in Setagaya and contains a free observation deck on the 26th floor.
- Gotokuji temple (豪徳寺) is the origin of the maneki-neko or beckoning-cat statuettes that bring good fortune to Japanese merchants the world over. Gotokuji station is on the odakyu line. However, the temple is also a short walk from Miyanozaka on the Setagaya line.
- Kinuta Koen (砧公園） is a public park with a museum of modern art.
- Komazawa Olympic Koen is a large public park, built for the 1964 Tokyo Olympics. It is about a 15-minute walk from Komazawa-Daigaku station, on the Tokyu Den-en-Toshi train line.
Everyday many people go to here to walk, go cycling, play, and so on.
- Setagaya Art Museum houses works by artists from the Primitivist School, such as Henri Rousseau. 17-minute walk from Yoga Station on the Den-en Toshi Line.
- Tamagawa Daishi (玉川大師) is a Buddhist temple, and a branch of Kawasaki Daishi. It isn't very large and the location is in a nondescript residential area, but its curious attraction is hidden: an underground passageway that snakes its way under the building. There are statues and altars with lighting at various points, but much of the tunnel is in absolutely darkness. It symbolizes a passage through the intestines of the Buddha (better not to dwell too much on the symbolism!) while the 88 Buddha statues in one of the chambers also symbolize the famous 88-temple pilgrimage in Shikoku. To get to Tamagawa Daishi, get off at Futako-Tamagawa on the Tokyu Den-en-Toshi Line (from Shibuya), and walk 10 minutes along the highway from Takashimaya department store.
