EITARO SOHONPO was established as Izutsuya, a confectionery shop, in Kudanshita, Tokyo, in 1818. After that, EITARO opened a food stand in Nihonbashi, selling Kintsuba, a traditional confectionery made from red bean paste. In 1857, the name was changed to EITARO, and they opened a shop in Nihonbashi where the main shop is presently located. EITARO developed Umeboshi Ame candy so that aruheito (toffee), which was expensive at that time, could be offered to all classes of people. Since then, the company has continued to develop Amana Natto and Kuroame candy, always responding to the tastes of the times with originality and ingenuity, and still continues to pass on the taste of Edo confectionery as it has always done.
EITARO now has five brands, EITARO SOHONPO, Ameya Eitaro, Nihonbashi Eitaro, Karada-ni-Eitaro, and Tokyo Peasen which all offer various products that have different concepts and customers, ranging from brands specializing in gifts to healthy products.
EITARO renovated the Nihonbashi main shop in August this year and keeps challenging new things while protecting the traditional flavors that have been preserved for 200 years.

Dorayaki Machine

Along with the completion of their Hachioji Factory in 2013, EITARO adopted a Dorayaki Machine, and they added another one in February 2020 in line with the increase in production volume.
Nihonbashi Dorayaki, whose standard method is to seal the pancakes after depositing the red bean paste, are packaged individually and has a long shelf life, increasing the demand as a souvenir and for some seasonal events.
These machines also produce dorayaki with various sizes, batter, and filling depending on the brands such as a product that is finished up by putting topping on a conveyor belt and a cold product that uses fresh cream.
EITARO mentioned about the machines, “There are not many parts and the operation is easy to understand. The thickness of pancakes varies per product, but adjusting the batter volume and heat is easy and stable at the same time.”
