If you want to experience a truly local Japanese sweet, Arai-ya’s Miso Manju is something special. Unlike standard manju, this version blends the rich umami of miso into the dough, creating a unique balance of sweet and savory flavors.
What makes Arai-ya stand out is that you can compare three classic types of anko (bean paste) in one place: smooth, chunky, and white bean.
What Is Miso Manju?
Miso Manju (味噌饅頭) is a traditional Japanese steamed bun made with dough that includes miso (fermented soybean paste) and filled with sweet bean paste.
Key Features:
Soft and fluffy outer dough
Subtle salty-sweet flavor from miso
Rich umami taste
Different fillings depending on the type
The miso adds depth, making it more complex than regular manju.
