Nunobiki Kogen Fukushima 2027: Sunflower Field + Wind Turbines Complete Guide
2026-10-22 · 8 Min. Lesezeit
Fukushima's wind-turbine highland + 500,000-sunflower field — one of Japan's most unique summer landscapes.
Nunobiki Kogen is an 1,100m-elevation plateau in Koriyama, Fukushima — Japan's largest wind farm (33 turbines) stands over a 500,000-flower sunflower field that peaks in mid-August. Combined with cooler summer temperatures and nearby Bandai-san onsen, it's a hidden gem for photographers and summer travelers escaping Tokyo heat.
💡Last content review: October 2026
Sunflower bloom timing varies ±1 week year-to-year. Check Koriyama tourism bureau or Nunobiki Kogen SNS for live bloom updates in late July.
⚡⏰ Peak-season rooms go first
Golden Week, Obon, New Year and the sakura and autumn-leaf peaks fill up fast. Once your dates are set, check availability now. Every week you wait, there are fewer rooms to choose from.

Why Nunobiki Kogen is unique
The combination of large-scale wind infrastructure + traditional flower landscape doesn't exist elsewhere in Japan. The turbines are 100m tall at the hub, 150m at blade tip — they tower over the sunflower field in a way that feels futuristic. The highland sits at 1,000m+, so August temperatures are 10°C cooler than Tokyo, making it a popular locals' summer escape. Clear days give views to Mt. Bandai and the Nasu range.

Photo tips
- ●Golden hour — 1-2 hours before sunset (17:30-19:00 in August), turbines + flowers both lit
- ●Low angle — crouch into the sunflower field, turbines as background
