SUP on Lake Aokiko, Serenity on the Water
Just a short drive from central Hakuba, Lake Aokiko offers something totally different from the adrenaline of the ski slopes: stillness. Glassy water, forested shores, birdsong, and the gentle rhythm of your paddle dipping into deep green, this is stand up paddleboarding in the Japanese Alps.
Whether you’re a first-timer or an experienced paddler, SUP on Aokiko is an unforgettable way to soak in the natural beauty of Nagano’s highlands.

Why Aokiko?
Lake Aokiko (literally “Blue Tree Lake”) sits quietly tucked in the mountains between Hakuba and Omachi. Unlike its larger neighbor Lake Kizaki, Aokiko is smaller, cleaner, and much quieter, a hidden gem that remains largely untouched by mass tourism.
There are no motorboats, no noisy jet skis just clean water, dense forest, and the occasional kingfisher darting over the reeds. On windless mornings, the lake is mirror-smooth, perfectly reflecting the sky and mountains. It’s no wonder it’s become a local favorite for SUP, canoeing, and nature photography.
What to Expect
SUP on Aokiko is accessible and beginner-friendly. Several local operators offer:
- Half-day tours with guides who provide all the gear and instruction
- SUP yoga sessions for the adventurous and flexible
- Rental boards for those who want to explore solo
- Family-friendly options, with large boards for kids to ride along
Guided tours often include breaks to swim, drift, or simply sit cross-legged on your board and listen to the water lap at the edges. In summer, the water is warm enough for a refreshing dip — just don’t forget your towel and sunscreen.

When to Go
- Best months: June to early October
- Best time of day: Mornings for calm water and cooler temperatures
- What to bring: Swimsuit, quick-dry clothing, hat, water shoes, sunscreen, and a waterproof camera if you’ve got one
Aokiko is especially stunning in early summer when the forest is deep green, and again in October, when the shoreline trees burst into color.

How to Get There
Lake Aokiko is about 25 minutes by car from Hakuba. Some activity providers offer pick-up and drop-off services, and there’s limited free parking by the lake.
Look for trusted local operators like Evergreen Outdoor Center or Lion Adventure, who provide safe, guided experiences in both English and Japanese.
Reconnect and Float Free
SUP at Aokiko isn’t about speed or performance. It’s about presence. Whether you’re gliding across still water at sunrise or floating under a canopy of stars after sunset, it’s one of those rare mountain moments that leaves you feeling lighter — and a little more connected to the world around you.
