神楽坂 Wiki知識 その1
The main road of Kagurazaka was once at the outer edge of Edo Castle, opposite the Ushigome bridge over the castle moat, and has always been busy because of this privileged location. In the early 20th century, the area was renowned for its numerous geisha houses, of which several remain today. Currently, Kagurazaka is experiencing a popularity boom due to its traditional, sophisticated atmosphere on the edge of modern Shinjuku ward.
Kagurazaka is also widely regarded as an important center of Japanese cuisine. Several old and famous “ryotei” are to be found in the winding back streets, often accessible only by foot. These ryotei provide expensive “kaiseki” cuisine, which is generally regarded as the pinnacle of Japanese food. Ryotei also allow diners to invite geisha to provide entertainment during the course of the evening.
While it retains a traditional Japanese atmosphere, Kagurazaka now boasts a significant French presence with many French expatriates living in the area due to the proximity of l’Institut Franco-Japonais de Tokyo.
