Seiho aims at being a specialized trading firm that can participate as a partner in the new business development of its clients.

Seiho's greatest asset is the trust endowed by clients, which has been cultivated over 200 years since its foundation in 1805. Starting with the sale of brushues, inks, and paints, Seiho formed a base as a dye wholesaler, and after the World War II, it has grown up as a trading firm specializing in chemical products, handling petrochemicals and fine chemicals.
