Oike

This dive site, Oike, is a unique marine lake located in Aigaura, Minami Ise, Japan. With a maximum depth of 6 meters and an average depth of approximately 3 meters, it offers a sheltered and calm environment ideal for beginner divers and training. As a rare marine lake, its contained nature allows for easy navigation, making it a perfect spot to practice skills and observe marine life in a tranquil setting. Oike is particularly rich in macro life, including various gobies such as Satsuki and Tatsu gobies, Chagara, and blue sea urchin nudibranchs. While primarily known for its smaller inhabitants, the site also occasionally hosts larger fish, and rare migratory species like Kaiwari and barracuda have been observed, offering both macro and wide-angle photographic opportunities. The sheltered conditions of Oike make it an enjoyable dive site almost year-round, though seasonal changes may influence migratory fish sightings. It is highly recommended for divers seeking a calm environment for training, macro photography, or simply a relaxed dive. Freedivers and snorkelers will also find the shallow, clear waters and abundant small marine life highly suitable for their activities, offering a gentle introduction to Japan's rich underwater ecosystems.
