Nagano Meijo is a sake brewery based in Nagano Prefecture the mountainous inland region of Honshu, Japan, known for exceptionally clean water from the Japanese Alps and a cool climate suited to slow, careful fermentation. The brewery produces Tokubetsu Junmai and Junmai Daiginjo expressions under the Tanada label, using locally grown rice and the region's soft mountain water.

The Tanada range covers the Tokubetsu Junmai (a step above standard Junmai, with higher rice polishing and specific brewing conditions) and lighter Ginjo expressions. Nagano sake is characterised by clean, delicate flavour development the cool climate and mountain water produce a particularly crisp, mineral-forward sake profile. For on-premise programmes offering sake by the glass alongside Japanese food or as part of an Asian spirits programme, Nagano Meijo's Tanada range provides documented mountain-origin provenance at accessible price points.
