Eitaro Sohonpo Co., Ltd. (Headquarters: Nihonbashi, Chuo-ku; Representative Director and President: Masami Hosoda, hereinafter 'Eitaro Sohonpo') and Funabashiya Co., Ltd. (Headquarters: Koto-ku, Tokyo; Representative Director: Kyoko Kamiyama) will implement a joint 'Black Syrup Distribution Campaign' at each company's main store, aiming to make more people aware of the appeal of black sugar, coinciding with 'Black Sugar Day' established on May 10th.
This initiative was born from the idea of 'what can we do together?'. It is carried out with the desire to widely convey the value and deliciousness of black sugar, one of Japan's food cultures that both companies have cherished, and to raise awareness of 'Black Sugar Day' itself. Black sugar is a natural sweetener that utilizes the inherent flavor of sugarcane, possessing a rich taste that varies by origin and manufacturing method. Among them, black sugar inherited in Okinawa is one of the symbols of food culture nurtured by a long history and climate. On the other hand, in modern times where food culture is diversifying, opportunities to encounter black sugar are becoming fewer than before. Against this backdrop, Eitaro Sohonpo and Funabashiya aim to provide an opportunity for new discoveries of black sugar's appeal and to pass on its value to the next generation. We hope that by creating opportunities for many people to experience the profound taste of black sugar, and by expanding the circle of companies and individuals who share the same vision, 'Black Sugar Day' will grow into a more widely cherished commemorative day.
What is 'Black Sugar Day'?

[About Funabashiya]
Founded in 1805 during the Edo period, Funabashiya is a Kanto-style kuzumochi shop celebrating its 221st anniversary in 2026. Funabashiya's kuzumochi is a 'rare fermented food in Japanese confectionery' made by lactic acid fermentation of 'wheat starch' for 450 days and then steaming it. This long period of lactic acid fermentation creates its unique chewiness and elasticity. Furthermore, driven by the desire to deliver natural products to customers, the company continues to adhere to a natural manufacturing method without preservatives. This traditional Japanese confectionery, being a fermented food and free of preservatives, is now attracting attention from health-conscious people.
