About Rausu
Rausu is a Shiretoko cold-water diving area known for kelp forests in summer, salmon and trout in autumn, and drift-ice diving in winter. It is a guide-led site with rich invertebrate life, a dramatic northern feel, and conditions that reward dry-suit comfort and careful timing more than easy tropical comfort. That makes it a strong fit for experienced divers who want wildlife, seasonal variety, and a very different ocean feel.
