Archiving the artisanal outputs of the Five Lakes basin—where mineral-rich water and high-altitude drainage define the regional standard.
Archiving the geological and climatic strata that power the Yamanashi highland yields.
The soil is composed primarily of **porous volcanic ash** and weathered basalt from Mount Fuji's historical eruptions. This creates a high-drainage environment that prevents root rot during the rainy season while providing unique mineral traces (Vanadium and Magnesium) to the produce.
Edaphic Note: High Mineralization / Low Retention
At an elevation of 830m, the region experiences a sharp **diurnal temperature delta**. The intense UV exposure during the day triggers high sugar production (photosynthesis), while the rapid cooling at night "locks in" acidity, a technical requirement for premium viticulture.
Atmospheric Note: High UV / Thermal Inversion
Yamanashi is the birthplace of Japanese viticulture. The Koshu grape, uniquely adapted to the regional volcanic soil, produces a light, acidic white wine that serves as the technical liquid pairing for delicate Setouchi seafood and highland dashi.
Basaltic Lava / Porous Ash.
Yuzu, White Peach, High Mineral.
"The high UV exposure at 830m elevation thickens the grape skins, resulting in a higher concentration of polyphenols compared to lowland vineyards."
Premium ExportA specialized botanical yield. Lavender is harvested in July for essential oils, dried sachets, and the iconic floral soft-serve found on the northern shore.
Yamanashi has a 1,000-year history of crystal carving. Local artisans utilize volcanic quartz to create high-integrity jewelry and technical optical glass.
Engineered for the sharp temperature delta between day and night. This produce is famously sweet and is often grilled with soy sauce at lakeside stalls.
The primary hub for lavender-based assets and regional perfumes.
