Most visitors associate Japan with sake, not wine — but tucked into the mountain valleys west of Tokyo is a wine region with over a century of history and a grape variety that exists almost nowhere else on earth. Yamanashi Prefecture, and specifically the town of Koshu (home to the Katsunuma district), is Japan’s wine heartland, built around a pale pink-skinned grape called Koshu. If you want to taste something genuinely Japanese that isn’t food, a day trip to this region is one of the most rewarding — and least touristed — things you can do within range of Tokyo.
What Makes Koshu Grapes Different
Koshu is Japan’s only indigenous grape variety grown specifically for wine, and it’s been cultivated in the Katsunuma area for well over 1,000 years, according to local legend tracing back to a monk who planted vines near Daizenji Temple. Genetic testing has shown the grape’s ancestry stretches back through the Silk Road to the Caucasus region, which is part of why in 2010 the OIV (the international body that regulates wine grape naming) officially recognized Koshu as a true Vitis vinifera variety — a rare distinction that lets Japanese producers label and sell it in the EU as “wine” rather than a generic fruit product.
In the glass, Koshu is almost always a dry or off-dry white. It’s light-bodied, low in tannin, often around 11–12% alcohol, with delicate citrus, white peach, and sometimes a faint saline minerality. It’s built for pairing with Japanese food — sashimi, tempura, delicate dashi-based dishes — rather than the bold, oaky profile many visitors expect from “wine country.” Don’t go in looking for a Napa Cabernet; the pleasure here is in the subtlety.
Katsunuma: Japan’s Wine Valley
The district of Katsunuma, within Koshu City, is the center of it all — a valley of terraced vineyards ringed by mountains, with dozens of wineries within a few kilometers of each other. The easiest way in is by train: from Shinjuku Station in Tokyo, take a limited express (the “Kaiji” or “Azusa” line) to Katsunuma-budokyo Station, a ride of about 1 hour 20 minutes to 1.5 hours, costing roughly ¥4,000–¥4,500 one way with a reserved seat. Slower rapid/local trains run the same route for less (closer to ¥2,500) but take nearly two hours.
From Katsunuma-budokyo Station, some wineries are a 10–15 minute walk, but many are spread across the hillsides and are easier reached by rental bicycle (available near the station), taxi, or by joining a tour. If you’re driving yourself, remember that tasting and driving don’t mix — and designated-driver services are uncommon outside major cities, so plan a non-drinking driver or stick to wineries within walking distance of the station.
If navigating a rural wine region without Japanese and coordinating multiple winery visits sounds stressful, this is one of the situations where hiring a private guide or driver for the day genuinely pays off — Katsunuma’s wineries don’t always have English signage or English-speaking staff, and a guide can also handle reservations that are otherwise hard to arrange in advance.
Wineries Worth Visiting
Budget: Many wineries offer free self-serve tasting corners where you buy small pours by the glass, typically ¥300–¥600 each. Mercian Wine Market’s Katsunuma facility and several smaller family wineries along the main road operate this way — you can sample four or five wines for under ¥2,000 total with no appointment needed.
Mid-range: Lumiere Winery and Marufuji Winery (which produces the well-regarded Rubaiyat label) both offer guided cellar tours with structured tastings, generally ¥1,000–¥2,000 per person, often requiring a reservation made a few days ahead, especially on weekends. Lumiere also has a striking stone-walled underground cellar built in 1901 that’s worth seeing even if you’re not a serious wine drinker.
Splurge: Grace Wine (Château Grace Yamanashi), one of Japan’s most internationally respected Koshu producers, offers premium tasting flights pairing their top cuvées, and their single-vineyard bottles run ¥4,000–¥8,000+, well above the ¥1,500–¥2,500 you’ll pay for an entry-level Koshu elsewhere. Suntory’s Tomi no Oka Winery, a bit further out, has a more polished visitor center with a restaurant and panoramic vineyard views, suited to travelers who want a full afternoon rather than a quick stop.
Best Time to Visit
Harvest runs roughly early September through October, and this is when the vineyards look their best and wineries are at their busiest — book tastings ahead if visiting on a weekend during this window. Early December brings a joint wine festival in the Katsunuma area where multiple wineries pour together at a central venue, a good option if you want to sample widely without visiting each winery separately. Spring (April–May) is quieter and pleasant for walking the vineyard roads, though the vines themselves are unremarkable to look at before leaf-out. Winter is low season — some smaller family-run tasting rooms reduce their hours or close for stretches, so call ahead if visiting December through February.
Common Mistakes Visitors Make
- Assuming it’s like sake. Koshu wine and sake share nothing beyond being Japanese alcoholic drinks — different raw material, different production method, different flavor profile entirely. Staff are used to this confusion but it’s worth knowing before you ask for “the house sake” at a winery.
- Not checking opening hours. Many smaller, family-run wineries in Katsunuma close by 5pm and may shut entirely on irregular weekdays, especially outside harvest season. Larger operations like Suntory and Mercian keep more predictable hours (typically 9:30am–4:30 or 5pm), but it’s worth confirming before making the trip.
- Underestimating the walking distance between wineries. On a map, Katsunuma’s wineries look clustered, but the terrain is hilly and distances between the farther-flung properties can be 3–4 km — manageable by bike, tiring on foot in summer heat.
- Forgetting tasting fees are often cash-only at smaller family operations, even though card payment has become more common at larger wineries.
Buying Bottles to Bring Home
Most wineries sell their own bottles on-site, usually cheaper than you’ll find in Tokyo department stores, and some offer shipping within Japan if you don’t want to carry glass bottles for the rest of your trip. If you’re buying at a duty-free counter in an airport or at a tax-free-registered shop, remember that the price tag you see isn’t necessarily what you pay — Japan’s consumption tax rules around exported goods and alcohol have specific conditions, which is worth understanding before you assume a bottle is cheaper than it looks; see our guide to Japan’s consumption tax and checkout pricing for how this works.
If you’re making a full day of it and staying overnight in nearby Kofu city rather than rushing back to Tokyo, note that check-in procedures at Japanese hotels require showing your passport regardless of nationality — our guide to hotel check-in rules for foreign guests covers what to expect at the front desk.
Koshu wine isn’t going to dethrone Bordeaux, and nobody in Yamanashi is pretending it will. What makes the trip worthwhile is tasting something that genuinely couldn’t exist anywhere else — a 1,000-year-old grape, grown in one small valley, made by people who are quietly serious about getting it right.
