Origin of Our Name

Scarlet knotweed flowers bloom in autumn everywhere around Ako Castle. We took our company name “Tateho” (standing buds) from the knotweed flowers that set the fields ablaze with color. In fact, the name of the city, Ako (red buds) is derived from the knotweed flowers as well.

Scarlet knotweed flowers are the origin of the name of Tateho, manufacturer of magnesium oxide, magnesium hydroxide or ceramic products.

Corporate Symbol

Our corporate symbol, which represents the Identity of the Tateho Group in visual form, is displayed in ultramarine, a color of the ocean. Wave-like curves stand for the ocean, and their gentle arc indicates harmony with the present age, society and nature.

In contrast, the square shape framing the curves represent single crystal magnesia, our flagship product, and our outstanding capacity for technological development. The whole mark expresses what Tateho is, a company whose technologies are born from the bountiful ocean.

Tateho's logo symbolizes ocean, harmony with nature, single crystal magnesia.
In 2016, Tateho celebrated the 50 year anniversary.
