Château Mercian Finesse and Elegance of Japanese Wine.

Brand Concept

Finesse and Elegance of Japan for world’s wine connoisseurs

In these twenty years, we have been trying to embody the Japanese spirit, "Finesse and Elegance," in Château Mercian, and now believe it represents all the elements of the delicate terroir in Japan, including grapes, soils, and climate.

It was essential for us to find out the best environment condition, and the best area was chosen for each variety.


Our winemaking history dates back to 1877 when "Dai-Nihon Yamanashi Budoushu-Gaisha," the forerunner of Mercian Corporation, was established, and this marked an epoch in the Japanese viticulture.

In 1970, "Château Mercian" brand was born.
"Château Mercian," as a genuine successor of the Japanese viticulture history, brought a new era of the Japanese fine wine making.

Vineyards & Wines

Château Mercian derived from our terroir

As is often said about "terroir," we observed and studied the environment of each area to find out the best varieties in the vineyards. For example, the best region for Riesling is Akita prefecture considering its cooler weather, and Muscat Bailey A is the best in Yamanashi considering its climate as well as the excellent grape growers in the area. In addition to this, we regard it is essential to maximize the potential of the grapes which represents the delicate tastes and flavors of Château Mercian.

The growers and the members of Château Mercian and Research Institute are investigating together to obtain the best grapes to be used for our wines, and this collaboration will be continued for an indefinite period.
