Shinjuku is often known for its skyscrapers, shopping districts, and neon-lit nightlife. However, the area is also home to traditional wagashi shops and Japanese dessert cafes where visitors can experience classic Japanese sweets.
One dessert that becomes especially popular during colder seasons is oshiruko, a warm sweet soup made with red beans. With its gentle sweetness and the addition of grilled mochi or shiratama rice dumplings, oshiruko has long been enjoyed as a comforting winter dessert in Japan.
In this article, we introduce places in the Shinjuku area where you can enjoy red-bean sweets such as oshiruko and similar traditional Japanese desserts.
What Is Oshiruko? A Traditional Japanese Sweet

Oshiruko is a traditional Japanese dessert made by simmering red beans with sugar to create a sweet soup. It is typically served warm and often includes grilled mochi or shiratama rice dumplings.
The dessert has long been enjoyed during winter and is commonly served at wagashi shops, tea houses, and traditional cafes. Oshiruko is also sometimes prepared at home, making it a familiar part of Japanese food culture.
The Difference Between Oshiruko and Zenzai

Another dessert similar to oshiruko is zenzai. The two are often confused, and the terminology can vary by region.
Generally speaking, oshiruko is often made with smooth red bean paste, while zenzai typically uses whole red beans. However, the naming convention differs between regions of Japan, so the distinction is not always strict.
Both desserts share the same base ingredient—sweet red beans—and are classic examples of traditional Japanese sweets.
Red Beans in Japanese Dessert Culture

Red beans play a central role in Japanese wagashi. Many traditional sweets use sweetened red bean paste as a key ingredient.
In addition to oshiruko and zenzai, red beans are used in desserts such as anmitsu, dango, daifuku, and taiyaki. Several shops in Shinjuku offer these types of traditional sweets.
