Lake Akan

Must Do Experiences

• Glide across the tranquil lake on a 70-minute sightseeing steamboat cruise while taking in panoramic views of Mount Oakan and lush surrounding forests.

• Explore the fascinating Marimo Exhibition and Observation Center to see the rare, spherical algae known as marimo up close.

• Stroll through the nearby Lake Akan Ainu Kotan to experience authentic indigenous culture, traditional crafts, and captivating dance performances.

• Visit during the winter months to witness the spectacular frozen lake landscape and participate in thrilling ice activities like snowmobiling or ice fishing.

Hidden Gems

• Head to the observation deck on the top floor of the cruise ship for unobstructed, wind-free views of the caldera mountains reflecting perfectly on the water.

• Ask the crew about the underwater volcanic vents that create the unique thermal conditions necessary for the giant marimo to thrive in the wild.

• Visit the lake just after sunrise or right before sunset when the steamboat crowds thin out and the morning mist or golden hour light creates a mystical atmosphere.

What Makes it Special

• Lake Akan is one of the only places in the world where giant marimo moss balls grow naturally to the size of baseballs, protected as a Special Natural Monument.

• The cruise route is carefully designed to showcase both the dramatic volcanic caldera landscape and the serene, untouched primeval forests of eastern Hokkaido.

• Your ticket seamlessly combines a relaxing 70-minute surface cruise with an exclusive 15-minute observation center experience to view the lake's hidden ecological treasures.

Perfect Timing

When to visit for the best experience

The best time to take the cruise is in the early morning or late afternoon to avoid peak midday crowds and capture the most dramatic lighting over the caldera mountains. While summer and autumn offer lush greenery and stunning fall foliage, visiting between January and March transforms the lake into a magical frozen wonderland hosting the spectacular Akan Ice Festival.

Photography Guide

Capture the perfect shots

• Position yourself on the outdoor rear deck of the steamboat to capture the beautiful V-shaped wake trailing behind the ship with the volcanic mountains in the background.

• For the best lighting, book a late afternoon cruise to photograph the golden hour sun reflecting off the pristine lake surface and illuminating the surrounding forests.

• When inside the Marimo Exhibition Center, use a polarizing filter or press your lens gently against the glass to eliminate glare and get crystal-clear shots of the moss balls.

Cultural Etiquette

Respect local customs and traditions

When visiting the nearby Ainu Kotan village, it is respectful to listen quietly during traditional dance performances and ask for permission before taking close-up photographs of artisans at work. The Ainu people hold nature in deep spiritual regard, so visitors are encouraged to help preserve the lake's pristine environment by strictly avoiding littering or disturbing the local wildlife.

Special Events & Experiences

Enhanced experiences and seasonal highlights

• The Akan Ice Festival runs from late January to March, featuring spectacular fireworks over the frozen lake, ice sculptures, and traditional Ainu fire ceremonies.

• In autumn, the Lake Akan Autumn Foliage Cruise offers special narrated sailings highlighting the vibrant red and gold leaves reflecting on the water.

• During the summer, the Kamuy Lumina night walk illuminates the nearby forest with stunning digital art projections inspired by Ainu mythology.

Important Guidelines & Safety

Essential safety information and guidelines

• Always hold onto the handrails when moving around the steamboat, especially on the outdoor decks where the floor can become slippery from lake spray or winter ice.

• During the winter months, wear slip-resistant footwear and thermal layers, as temperatures on the open deck and around the frozen lake can drop well below freezing.

• Keep a close eye on young children near the boat railings and ensure they remain seated while the vessel is in motion.
