History
It all began in Osaka with a small-town factory producing detergent.
Founded by the previous generation's Yuichi Yoshida, Dainichi Chemical Co., Ltd. manufactured and sold solid dishwashing detergent, initially developed for commercial use and later adapted for home use.
The breakthrough that showcased their technical prowess to the world was the development of the "Sunsun Sponge," designed to pair perfectly with solid detergent. This sponge, with its remarkable durability lasting from several months to about a year, revolutionized the conventional concept of sponges and became a topic of widespread discussion.
The Sun Seven Series: Loved for over 50 years by water workers
Since its founding, the Sun Seven series of solid detergents has continued to research and evolve while maintaining its gentleness to the skin.
Over the years, leading to the current Sun Seven® HighR Series, various types and package designs have been developed.
Valuing each and every customer, we aim to make housework more enjoyable.
Motoyuki Yoshida, the founder's son, now leads the business. Alongside him, his wife and two sons are also involved, continuing the family legacy into its third generation.
With years of research and experience, and by listening to our customers' feedback, we are dedicated to providing products that enhance daily life. We will continue striving to deliver items that make a positive difference for our users.
