Question 1

When is the best time to scuba dive in Amami Oshima?

Accepted Answer

For warm-water reef and boat diving, July through early October is a practical starting point, but it is not a guarantee of calm seas. The Japan Meteorological Agency flags July through October for typhoon approaches, and May-June for the Baiu rains. North-side operators adapt their dive coast to the wind: East China Sea side sites are common in their southerly season, while Pacific-side beaches often replace them during winter northerlies. Winter to spring remains attractive for nudibranch photography. Choose travel dates by your intended sites and confirm the guide's weather-alternative plan.

Question 2

Can beginners dive around Tatsugo or Oshima Strait?

Accepted Answer

Yes, there are documented beginner-oriented guided sites, but conditions are not uniform. Native Sea Amami lists Sand Paradise and Yamamoto Special in the Tatsugo bay area as beginner-level boat dives, and Kohollo offers supervised trial dives in the southern Oshima Strait circuit. Certified fun dives require the appropriate certification card; non-divers must arrange a trial dive or training course. Exposed ocean sites and surf-affected beach entries may be unsuitable for a new diver even when other boats operate. Tell the guide your recent experience, swimming comfort, health history and any request for a refresher before reserving.

Question 3

Where can I snorkel with sea turtles on Amami Oshima?

Accepted Answer

The Amami tourism association names Yoan and Kuninao as places with turtle observations and recommends guided activities for better site judgment. LeapScubaAmami currently offers a small-group turtle snorkeling trip with a beach selected by conditions. Its own booking page also says a turtle encounter is never 100 percent certain. Kurasaki is a documented coral snorkel beach, while Ohama is a Naze-area beach and park with visitor facilities. Check wind, rip currents and boat traffic before any shore entry, wear flotation where appropriate, and never touch, follow or feed turtles.

Question 4

Can I scuba dive or freedive with humpback whales in Amami Oshima?

Accepted Answer

No. The published Amami whale-swim practice is a quiet surface-snorkeling observation, not a scuba dive and not a breath-hold duck dive. Local operators reproduce the Amami Whale and Dolphin Association voluntary rules, which make the captain responsible for deciding whether swimmers can enter the water and protect the whales' normal behavior. The winter humpback season is generally January to March, but eligibility is more demanding than regular beach snorkeling. Kohollo requires a relevant certification and strong open-ocean water skills. Boat-only watching is a separate option, and neither whale sightings nor swimming are guaranteed.

Question 5

Are dolphin swims and sperm whale encounters available all year?

Accepted Answer

No reliable year-round schedule was established. Kohollo advertises irregular dolphin swims in Oshima Strait and irregular sperm whale search trips from April through September, both dependent on wind and animal behavior. Its dolphin trip may permit controlled skin diving, whereas its whale-swim FAQ expressly forbids skin diving or scuba observation of whales. Do not transfer the rules or qualifications from one activity to the other. A sperm whale search offering is not proof that entering the water will be allowed on a given departure. Ask the current captain about species, behavior limits, association rules and the fallback if no animal appears.

Question 6

How do I visit Kakeroma Island from Amami Oshima for diving or snorkeling?

Accepted Answer

Travel first to Koniya in Setouchi Town. The municipality publishes Ferry Kakeroma passenger services between Koniya and either Sesou or Ikema on Kakeroma, typically about 20-25 minutes per crossing. Storms, vessel maintenance and community events can alter sailings; carrying a car is limited and requires advance coordination. Arrange transport on Kakeroma for beaches such as Surihama or for a stay with Diving and Pension RIKI. By contrast, Kohollo can run guided dive or snorkel boats around Kakeroma from the southern main island. Those boat excursions should not be mistaken for regular passenger transfers or unrestricted shore landings.

Question 7

Can I take a freediving course on Amami Oshima, and how deep can I go?

Accepted Answer

AMAMI Freediving currently advertises AIDA1, AIDA2, AIDA3 and coaching. Its AIDA2 outline includes theory and pool work around Naze and instructor-selected open-water sites near Koniya, plus formal buddy and rescue training. The published AIDA2 qualification contains a {{ 12 | distance:m }} to {{ 20 | distance:m }} constant-weight component, not a promise of a particular training depth in Amami. You must meet the stated swimming and medical prerequisites and arrange transportation to the meeting point, as the provider reports no normal pickup service. Courses depend on instructor scheduling and safe sea conditions.

Question 8

How do I plan for typhoons, rain and ferry cancellations?

Accepted Answer

The Japan Meteorological Agency describes Amami's usual rainy season as May-June and identifies July-October as months when typhoons can approach. Although July-September brings warm seawater, strong wind or swell can stop scuba boats, sea wildlife tours and the municipal Kakeroma ferry. Avoid an itinerary that depends on one irreplaceable Kakeroma return sailing or a fixed final-day dive. Keep a flexible indoor or forest day, follow the airport and municipal transport operator notices, and do not enter the sea because the weather is dry. Wind direction, surf and local tide matter more than a seasonal label.

Question 9

What can non-divers do while others scuba dive in Amami Oshima?

Accepted Answer

Amami offers substantial land and cultural choices. You can book a certified guide for the protected Kinsakubaru forest, join a tide-suitable mangrove kayak in Sumiyo, visit Amami Park and the Tanaka Isson Memorial Museum, or explore Naze restaurants serving keihan. Ohama Seaside Park and its marine exhibition are useful between boat trips. A Kakeroma day includes a separate ferry from Koniya and onward travel to Surihama beach or Ankyaba ruins. For a whale trip, ask whether boat-only watching is offered, as this does not require joining a restricted swim. Every outdoor outing remains weather-dependent.

Question 10

Do I need a marine park permit or tourism tax to snorkel and dive here?

Accepted Answer

The official pages reviewed for Amami Gunto National Park and the island tourism service did not establish one universally required recreational scuba marine tag or an all-island tourism levy. That absence is not a guarantee that every protected zone or specialist activity is open without permission. Follow operator prices and local restrictions; do not collect marine life or interfere with coral, and ask the managing authority about unusual activities. Kinsakubaru forest visits require a certified guide with capacity controls, while some Santaro night-road activities require advance reservations. Kakeroma ferry fares, dives and museums are separate charges.

Question 11

Where is the nearest emergency hospital for divers, and when can I fly?

Accepted Answer

Kagoshima Prefectural Oshima Hospital in Naze operates a 24-hour emergency center and a regional doctor-helicopter base. The hospital also describes a hyperbaric oxygen facility used for diving illness, but the appropriate chamber, staffing and treatment acceptance must be verified in an actual emergency. Call 119 for medical emergencies and 118 for marine distress. Discuss oxygen, boat communications and evacuation time with the dive operator before remote Kakeroma or outer-ocean trips. Kohollo says it will not schedule scuba on flight departure day; follow your own dive agency/computer no-fly guidance and obtain medical advice when needed.

Question 12

Which base should I stay in for a first Amami Oshima dive trip?

Accepted Answer

Tatsugo is useful when your priorities are north-side bay reefs, macro dives and beach entries such as Kurasaki. Naze is the main urban center, with bus connections, cash access, eating options and the regional emergency hospital. Setouchi/Koniya is the logical main-island base for the Oshima Strait, Kohollo departures and the municipal ferry to Kakeroma. The north-to-south drive makes switching between them less convenient than a map suggests. Confirm the operator's actual departure point and accommodation pickup limit before you book. Adding Kakeroma itself usually merits a separate day and independently arranged island transport.
