Nagano Prefecture, particularly the Shiojiri Kikyo Gahara area, is renowned for its wine production. Wine grape cultivation in this region began in 1890, driven by Japan's industrialization policies.
The introduction of Merlot, particularly from the efforts of Mr. Goichi Hayashi of Hayashi Farm, led to the breakthrough with the "Kikyo Gahara Merlot," which won the grand prize at an international wine competition in 1989.

This marked Nagano as a key wine region, sparking interest in European grape varieties such as Chardonnay, Sauvignon Blanc, and Cabernet Sauvignon.
A Perfect Climate for Grape Growing
The climate of Nagano - low rainfall, excellent drainage, and a long growing season - creates ideal conditions for wine grapes.
The region's varied topography allows for the cultivation of multiple grape varieties. This diversity has made Nagano grapes highly sought after, not only for local wineries but also for major international brands.
Nagano wines have gained significant recognition, being featured at prestigious events like the 2016 G7 Summit and the 2019 G20 summit.
The Shinshu Wine Valley Concept
Around 2010, Nagano experienced a boom in winery openings. By 2019, there were 52 wineries in the region.
In response to growing international acclaim, Nagano launched the Shinshu Wine Valley concept, which divides the prefecture into four key wine regions: Kikyo Gahara, Chikuma River, the Nihon Alps, and the Tenryu River valleys.

These regions host various wine events and festivals, allowing visitors to taste a variety of wines in scenic settings.
Experience the Joy of Meeting Winemakers
Nagano's wineries offer a unique experience where visitors can interact directly with winemakers. Many wineries have tasting areas and shops, and some even allow visitors to help with grape planting and harvesting.
Additionally, several wineries have attached restaurants, offering the opportunity to enjoy locally grown produce paired with the wines made from the very same land.
This connection between winemakers, their land, and the visitors who enjoy their products makes Nagano wine a truly exceptional experience.
