Aqua Cat Horomui Diving

Tucked along Hokkaido's waterfront in Japan, Aqua Cat Horomui Diving invites you to trade tropical islands for something a little different. Here an experienced guide leads you through the celebrated "Shakotan Blue" waters, shaped by Hokkaido's natural beauty. In summer you can admire dramatic formations such as columnar joints; in winter you might come face to face with the world's largest octopus and sea lions.

Courses and diving

As a PADI Resort with 3 PADI Instructors, Aqua Cat Horomui offers PADI Scuba Diving and PADI Freediving, with instruction available in English and Japanese. The signature Full-Day Dive Trip runs from USD 140 and fills roughly one day on the water. Divers may encounter sharks, whales and turtles among the local marine life.

The center keeps things comfortable with an onsite classroom, air conditioning, free Wi-Fi, a retail shop, a dive boat, food and drinks, and parking. Equipment sales and scuba equipment rental round out the offering, making it a welcoming base for anyone curious about cold-water diving in northern Japan.
