Experience the Blue Cave Cruise in Otaru This September!

 
Enjoy the Crystal-Clear Blue Cave with Your Family and Loved Ones
 
For those planning a fall trip to Otaru, the Otaru Shioya Blue Cave Cruise is highly recommended.
September is a season when the sea’s transparency reaches its peak, allowing you to enjoy the stunning fall scenery.
In 2025, Japan has a series of holidays in September—a 3-day holiday from September 13–15 and a 4-day holiday from September 20–23—making it a perfect time to enjoy sightseeing in Otaru.

Currently, the cruise does not enter the Blue Cave itself but passes nearby. Even so, the combination of the crystal-clear sea and the light-filled scenery creates a magical experience that will remain in your memory.
Enjoy this special time in Otaru with your family or loved ones.

Perfect Cruise Experience During Japan’s September Holidays

 
The Blue Cave Cruise is popular for a wide range of travelers, from families and couples to groups of friends.
 
Safe for families: Life jackets and attentive staff ensure even young children can enjoy the cruise safely.
Special moments for couples: The fall sunlight and calm sea create a romantic atmosphere.
Fun with friends: Sharing a unique experience together makes for unforgettable memories.
 
Since these holiday periods are popular, we recommend booking in advance.
 

Fall Magic of Otaru’s Sea

 
In September, the sea around Otaru is exceptionally clear, and the rippling light on the water creates a mesmerizing, almost magical scenery.
Currently, the cruise passes near the Blue Cave rather than entering it, but the contrast between the cave exterior and the sea remains spectacular.
After the peak tourist season, the calm and tranquil fall atmosphere makes it perfect for a relaxing cruise.

Additionally, the sea can feel chilly in fall, so bringing a windbreaker or light jacket is recommended for your comfort.
