The most popular exploration activity in Otaru! Allow yourself to be lured in to a dark cave, to find a glowing turquoise blue mysteriously shining in the darkness.

Otaru-born former diver is the owner of the boat, who knows the local oceans well. This tour was organized to preserve the natural environment by sharing the beauty of the blue cave, and the delights of Otaru's sea.

This is the only tour in Otaru that takes you to the Blue Cave in a "Glass Boat" where you can see the ocean floor beneath you.

The boat has a big roof and side seats for you to enjoy a comfortable cruise without being splashed by the waves.

After departure from "Shukutsu Marina", you can enjoy the surrounding views of the area on the way to the blue cave.

The boat slows down at popular view spots such as the 2 meter high rock island called "Todo(Sea Lion) Rock", and near the entrance of the blue cave, so everyone can have time to see both above and below the ocean. Of course, you also have plenty of time to enjoy the main attraction, the Blue Cave itself, with mysterious turquoise waters.

*Note: Some of the proceeds of the tour's revenue will be used for environmental conservation activities of the ocean.
  • English or 繁體中文 guide texts are provided describing the highlights of the tour, so you don't need to understand Japanese to enjoy!

  • Jump in our "Glass Boat" to see the ocean floor of Otaru through our glass windows below the ship! What a different view under the sea!

  • The meeting place "Shukutsu Marina" is just a 5 min walk from Otaru Aquarium. We recommend seeing the ocean animals there before or after the ocean tour. Otaru Aquarium opening hours: 9am to 5pm (last entry 4:30pm). Admission: Adults 1,400yen, Children (6-14) 530yen, Children (3-5) 210yen.
