About Long Beach
Long Beach is a relaxed Hokkaido shore dive with easy beach access, a short gear walk, parking nearby, and a shallow rock-and-cave route. Expect sandy entry, no restrooms, pockets of small marine life, and regular moon jellyfish, plus a low-key outing that works best on calmer winter days and suits easy photo-focused sessions.
