Spring (March–May): clean air, soft colors, and an easy pace
Spring in Koshu Valley has a calmness that’s hard to describe until you feel it. The air is crisp and clean, the mountains look close, and the region feels like it’s quietly waking up.
This is one of the best seasons for travelers who want a comfortable rhythm: tasting, conversation, vineyard scenery, and unhurried stops—without heat or crowds.
What spring feels like:
- Fresh, cool mornings and mild afternoons
- Clear views of surrounding mountains on many days
- A relaxed “shoulder season” feeling before summer
Why it’s a great season for wine tours:
Spring suits guests who want a smooth, balanced day. Winery visits feel intimate, and tasting rooms are comfortable even for longer tastings. It’s also a season where the countryside feels especially peaceful.
Summer (June–August): vivid green vineyards and bright energy
Summer in Yamanashi turns the valley lush and intensely green. Vineyards become vibrant. The countryside feels alive. It’s a season with a lot of visual beauty—especially if you enjoy photography, scenic drives, and a strong “summer Japan” atmosphere.
What summer feels like:
- Lush vineyard landscapes and deep green hillsides
- Warm days, sometimes humid (typical of Japan)
- A bright, energetic countryside mood
Why it’s still worth visiting:
Summer is often underestimated for wine travel, but Koshu Valley has a strong advantage: Wineries are built for hospitality and comfort,and tastings are enjoyed in calm indoor spaces. This season is ideal for travelers who want the greenest landscapes and the most lively countryside feeling.

Autumn (September–November): harvest atmosphere and the richest scenery
Autumn is the season many travelers imagine when they picture wine country—and the Koshu Valley delivers beautifully.
The valley becomes warmer in color and tone: golden light, vineyard rows shifting in texture, and an overall feeling of depth in the landscape. It’s also the time of year when the region feels most closely connected to wine itself.
What autumn feels like:
- Comfortable temperatures and clear afternoons
- A “wine country” mood that feels complete and grounded
- Rich seasonal colors throughout the countryside
Why autumn is ideal for many guests:
If you want the classic wine-region feeling—vineyard scenery, tastings, and the sense that the region is at its most wine-focused—autumn is the easiest recommendation.
Winter (December–February): quiet wineries, clean views, and a premium calm
Winter in Koshu Valley is for travelers who like calm spaces and a quieter version of Japan.
The vineyards rest, the air becomes sharper, and the scenery turns minimalist—but in a beautiful way. On clear days, visibility can be stunning. Wineries feel peaceful and unhurried. And tastings often become deeper and more conversational.
What winter feels like:
- Crisp air and a “slow Japan” atmosphere
- The valley feels spacious and still
- More privacy and fewer distractions
Why winter guests often love it:
Winter is especially good for couples and travelers who enjoy an intimate, reflective pace. The experience becomes less about “doing many things” and more about savoring moments—long tastings, calm lunch, and meaningful conversations.

Koshu Valley is not just wine—it’s place
Koshu Valley changes more than most visitors expect with the seasons.
And that’s why it’s such a rewarding destination. The experience is not only the tasting—it’s the scenery, the pacing, the conversations, and the sense that you’re visiting a living region with its own rhythm.

If your schedule is flexible, there may still be options closer to your travel date.
