Scuba

What It Feels Like

Choose a base for the diving you want: Jogashima for shore sessions, Miyagawa Bay for short boat trips, Hayama for rocky reefs and macro photography, or Odawara for separately reached shore facilities. Miura Umi-no-Gakko and NANA publish guided programs for certified divers. Plan a full day around one local departure, with transfers between coastal bases arranged separately.

Planning Playbook

Operator Checklist

Reserve the guide, language support, meeting point and rental sizes together. Bring certification and recent dive records. Miura Umi-no-Gakko generally uses drysuits from mid-October to mid-June; this is its practice, not a universal requirement. Ishibashi lists no drysuit or dive-computer rental. Ask each operator about thermal equipment and instruction before arrival.

Conditions Fallback

If weather and water can disagree shifts, confirm site selection with your operator before departure.

Avoid

Do not ignore weather and water can disagree advisories from local operators.
