For the more than 80 odd years since our founding in 1932, Yamadaya has devoted itself to the production of momiji-manju (a maple-leaf-shaped bun with bean-jam filling), our main product.
We are extremely proud of our momiji-manju, and we maintain our own special bean-jam production plant, which delivers an original flavor that has been highly popular with a great many customers.
Our Toyoka (Paulownia cake) also received the Honorary President’s Award at the 24th All-Japan Confectionery Expo (2002), and we continue to work for the creation of new textures and flavors.
For the future, we are focusing on research aimed at meeting the food needs of our customers, and paying attention to safety and security of food, while maintaining our traditional old-shop flavor, in order to succeed as a company that continually develops with the times.

Toyoka (Paulownia cake) are baked with our company’s own red bean paste and mochi rice flower. This cake has a delicate flavor, and is ideal when served with tea.

A new type of sweet blend of Japanese and Western produced by anather brand of Yamadaya "RAKU Yamadaya".
