Common coastal sights around Kumejima () include Hatenohama () and the Tatami-ishi rocks on Ojima (, ). The first is an offshore sandbar reached by boat; the second is a nationally designated Natural Monument. Although both are coastal sights, their landscapes and visiting requirements differ. This article draws on official Okinawa tourism and Kumejima Town information checked on 29 October 2026. Individual tour prices and same-day boat operations are outside the verified comparison. For more about the island, see the Kumejima travel guide.

Key points

  • Hatenohama is an offshore white-sand sandbar near Kumejima. Official information says it must be reached by boat, so it cannot be planned as a beach accessible directly by road.
  • Ojima Tatami-ishi is formally listed as “Tatami-ishi on Ojima, Kumejima Town” and appears on Kumejima Town’s list of nationally designated Natural Monuments.
  • Official information also introduces Eef Beach () and historical castle ruins on the island. These are different kinds of destinations from an offshore sandbar.
  • Whether boats operate that day, the price of each tour, and swimming hours must all be checked separately using current operator information.
  • When planning Kumejima, treat activities requiring sea transport and visits to scenery on the island separately.

How do Hatenohama and Tatami-ishi differ?

Comparison Hatenohama sandbar Tatami-ishi on Ojima
Official name
Type of scenery Offshore white-sand sandbar near Kumejima Tatami-ishi rock formations on Ojima
Official access or protection information Boat access required Nationally designated Natural Monument
Main question before visiting Is a suitable boat service available on the day? Confirm that the intended site is Tatami-ishi rather than the offshore sandbar
Real-time data not provided here Sailings on specific dates and tour prices Current operations of individual facilities and visit activities

These places are not interchangeable simply because both have coastal names. The key requirement for Hatenohama is boat access, while Tatami-ishi’s defining feature is its protected natural landscape. Keeping these separate helps avoid treating both as the same destination when planning transport.

Hatenohama: Check boat arrangements first

Official Okinawa tourism information describes Hatenohama as an offshore white-sand sandbar reachable by boat. This establishes the basic fact that you cannot drive directly to it, but it does not establish the departure location, schedule, or activities for a particular date.

Trip question Officially confirmed information Current details to check
Can the sandbar be reached directly by road from the main island? It must not be planned as a road-access destination; official information requires a boat Which operator offers the visit you want
Can a sea trip be arranged? The official guide describes travel there by boat Actual boat services on the intended date
Ferry or tour price No single verified price is available for this page Ticket and charging conditions for the service you choose
Is swimming possible? This page does not give swimming hours for a specific date Sea conditions and notices about the activity on the day

If sea activities are disrupted, do not automatically apply the cancellation policy of another island or operator. This article retains only the sourced access information and does not invent cancellation charges, refunds, or alternative departures.

Tatami-ishi on Ojima: A different natural landscape

Kumejima Town’s cultural property list places Tatami-ishi under nationally designated Natural Monuments. This official designation is important: Tatami-ishi is more than a coastal attraction with “rocks” in its name; it also has a formal protected-cultural-property status.

Perspective Hatenohama Tatami-ishi on Ojima
Main landscape Sandbar and white sand Tatami-ishi geological formations
Key condition Boat transfer Nationally designated Natural Monument status
Can the same visiting arrangement be substituted? The two are different kinds of destinations Do not apply the sandbar boat journey to a Tatami-ishi visit

The cited Kumejima Town cultural property page establishes Tatami-ishi’s protected status. It is not treated here as a same-day notice about operations at facilities on site.

What other types of scenery are found on Kumejima?

Officially mentioned sight Japanese name Type or identifying feature
Hatenohama Offshore white-sand sandbar
Eef Beach Beach scenery on the island
Tatami-ishi on Ojima , Nationally designated Natural Monument
Historic castle ruins Historic Kumejima sites described officially Cultural landscape different from the beaches

If visiting both the sandbar and other island sights, list activities requiring boat connections separately before planning other kinds of scenery. Do not assemble an entire day’s schedule using unverified journey times or activity costs.
