This article from Metropolis magazine is a list of my favorite shoutengai in Tokyo. Shoutengai are shopping arcades. Here you will find small ma and pa shops selling freshly made tofu, vegetables, seafood, meats, and much more. This is a great way to spend some free time while exploring the city.

While the one-stop food shopping at Tokyo’s depachika is an amazing experience, the gourmet eats come with a high price tag. At the other end of the spectrum are the places where most Japanese do their daily shopping: neighborhood shopping streets known as shotengai, where you’ll find mom and pop shops selling vegetables, fish, meat, rice and even handmade tofu. The Tokyo Shotengai website (http://meturl.com/shotengai) lists over 550 of these shopping streets; here are some of our favorites.
This foodie neighborhood is filled with many fantastic shops along the main drag. Try 50-ban (3-2 Kagurazaka) for its steamed buns, Kintokiya (2-10 Kagurazaka) for wagashi made from sweet potatoes, and the gorgeousRakuzan (4-3 Kagurazaka) for tea. Isuzu (5-34 Kagurazaka) offers a variety of Japanese-style sweets and, if you walk along the street far enough, Baikatei (6-15 Kagurazaka) has fantastic handmade wagashi. Nearest station: Iidabashi
Just outside of Nippori station lies the Yanaka shotengai—very typical of what you would imagine an old-style shopping street to be like. Two of the area’s meat shops are famous for their menchikatsu: Niku no Sato (3-13-2 Yanaka) and Niku no Suzuki (3-15-5 Nishi-Nippori). Goto no Ame (3-15-1 Nishi-Nippori) has a colorful selection of candies. There are many options, including deep-fried tofu balls known as ganmodoki, atMusashiya (3-9-15 Yanaka), oyatsu-pan (snack breads) at Atomu Bakery (3-11-14 Yanaka), and skewered and grilled seafood at Fukushima Shoten (3-13-4 Yanaka). Note that a lot of the shops are closed on Mondays.Nearest stn: Nippori. www.yanakaginza.com
The historic Ningyocho district is always a delight to visit. While you’ll find many shops selling the local specialty, ningyoyaki (small cakes filled with azuki bean paste), there are many other interesting stores. On the famous Amazake Yokocho shotengai is Futaba Tofu (2-4-9 Ningyocho), with a variety of tofu products and also the sweet, creamy drink for which this street is named. Hojicha tea is the specialty of Morinoen (2-4-9 Ningyocho), while the long line outside the tiny Yanagiya (2-11-3 Ningyocho) is a testament to the popularity of its taiyaki sweet-bean cakes—considered one of the three best varieties in the city. Ningyocho’s most famous restaurant may well be Tamahide (1-17-10 Ningyocho), renowned for its oyako-don rice bowls. Nearest stn: Ningyocho.
Just north of Kichijoji station is Sun Road, a covered shotengai filled with many small shops. Among the several worth exploring are traditional German bakery Linde (1-11-27 Kichijoji-Honcho) and Meat Shop Sato (1-1-8 Kichijoji-Honcho), which is famous for its menchikatsu and wagyu and which also has a popular restaurant on the second floor, usually with a long line. Okashi no Machioka (1-15-1 Kichijoji-Honcho) will have your eyes spinning with all of the different types of candies, sweets and snacks. In the evening, the Harmonica Yokochostrip is filled with small restaurants that are perfect for a drink and some nibbles. Tecchan is a popular yakitori spot—if you can squeeze in (1-1-2 Kichijoji-Honcho). Nearest stn: Kichijoji.
This popular foodie street in the heart of the city is easy to navigate. The renowned Mamegen (1-8-12 Azabu-Juban) tempts customers with over 90 varieties of flavored rice crackers, including uni, wasabi and curry, but it’s the shio-okaki (deep-fried and salted) that are irresistible. The taiyaki at the extremely popular Naniwaya Sohonten (1-8-14 Azabu-Juban) are made by the shop’s fourth-generation owners. Hasegawa Saketen (2-2-7 Azabu-Juban) has well-selected sake, shochu and umeshu. If you’re craving meat, the yakitori at Abe-chan (2-1-1 Azabu-Juban) will hit the spot. Alternatively, slurp up some soba noodles at Nagasaka Sarashina (1-8-7 Azabu Juban), notably the delicate, white sarashina noodles. Nearest stn: Azabu-Juban.
