Kadoya Hotel
Kadoya Hotel is a long-standing hotel, operating in Nishi-Shinjuku for over half a century. Its location is outstanding, located just about 3 minutes on foot from the west exit of JR Shinjuku Station, the Toei Shinjuku Line’s Shinjuku Station, and the Toei Oedo Line’s Tochomae Station.
It may be small, but it's got everything you need. Plus, the bedding is the same Tokyo Nishikawa brand I use at home.
Katsushika Shibamata Tora-san Museum
Katsushika Shibamata Tora-san Museum is a popular spot located within Shibamata Park about three minutes on foot past Shibamata Taishakuten.
I haven't seen the movie, but from the moment you leave the station, you see Tora-san statues and posters everywhere. Inside the museum, the exhibits really help you understand the era that Tora-san represents.
Kayanoya
A former soy-sauce storehouse turned specialty ingredients shop. Kayanoya has spent 120 years helping more people enjoy “Washoku”, the world-recognized intangible cultural heritage of Japanese cuisine, with easy to use ingredients.
All their products are healthy and organic, and the prices are really reasonable. I buy their stuff all the time.
