Ryūken Tsuchiya (土屋龍憲, 1858–1940)
Co-founder of modern Japanese commercial wine — sent to France with Masanari Takano in 1877 and shaped Katsunuma’s next half-century
Life
Ryūken Tsuchiya (土屋龍憲) was born in 1858 in Katsunuma, Yamanashi — six years after his future colleague Masanari Takano. He was selected alongside Takano in 1877 by the Yamanashi prefectural government for the historic French study mission. Both men were in their twenties, from local farming families, and chosen for what the prefectural government believed was their adaptability to a long unfamiliar curriculum.
The two trained in France through 1878–1879, focused on Bordeaux and Loire winemaking practices. They returned to Yamanashi and co-founded the Dai-Nihon Yamanashi Budōshu Kaisha in Katsunuma — the first modern Japanese commercial winery.
A Six-Decade Career
Where Takano died in 1923 at age 71, Tsuchiya lived until 1940, dying at 82. His longevity meant he served as a continuous presence in Katsunuma wine for nearly six decades. He took on training roles for younger Katsunuma vintners, advised on technical questions through the company’s several corporate reorganizations, and lived to see the founding of the Mercian brand’s direct corporate predecessor.
His role in Japanese wine history is sometimes overshadowed by Takano’s — the founding-narrative emphasis tends to favor the more senior partner — but Tsuchiya’s sustained career arguably had a deeper practical influence on the actual training of Katsunuma’s next generation of winemakers.
Why He Matters
With Takano, Tsuchiya is one of the two figures who turned commercial Japanese wine from a state-backed experiment into a working industry. His longer career meant that the practical knowledge he had brought back from France in 1879 was passed forward to Yamanashi vintners working into the 1930s — a direct lineage from the Meiji Restoration’s wine-modernization moment to the prewar Japanese wine industry.
