When traveling around Ishigaki Island, distinguish between viewing the sea from shore, taking a boat to see underwater scenery and actually entering the water. Some attractions focus on coastal scenery, while others have beach facilities. Although Kabira Bay is known for its views and glass-bottom boats, official tourism information explicitly states that swimming and snorkeling are not permitted at the nearby beach. Based on Okinawa’s official tourism website (checked 2026-10-29), this guide explains the different attractions and boundaries for marine activities. For an island overview, see the Ishigaki travel guide.

Key points

  • Tamatorizaki Observatory, Hirakubozaki Lighthouse and Oganzaki Lighthouse are coastal viewpoints on Ishigaki Island.
  • Kabira Bay () is suitable for enjoying coastal scenery and viewing underwater landscapes from a glass-bottom boat, but swimming and snorkeling are not allowed at the nearby beach.
  • Official tourism information describes lifeguards and several facilities at Maesato Beach (). Actual services still need to be checked for the relevant season.
  • Okinawa’s official safety advice says to swim only in designated swimming areas, follow lifeguards’ instructions and watch out for currents.

Types of attractions: Decide what you want to see

Attraction or category Officially confirmed features Main type of activity Question to distinguish when choosing
Tamatorizaki Observatory One of Ishigaki Island’s main ocean viewpoints Sightseeing Is the main goal to view the sea from land?
Hirakubozaki () Lighthouse A major viewpoint listed by the official source Sightseeing Is the itinerary focused on coastal terrain and distant views?
Oganzaki Lighthouse A major viewpoint listed by the official source Sightseeing Would another coastal viewpoint fit the plan?
Kabira Bay Seascapes and glass-bottom boats Viewing underwater scenery from a boat Is it clear that swimming and snorkeling are prohibited at the beach?
Maesato Beach Officially described as having lifeguards and various facilities Beach activities Which services are available in the season, and is the swimming area open?

Scenic viewpoints are not the same category as beaches where visitors can enter the water. For a trip focused on seascapes, swimming access need not be a criterion. But if the plan includes swimming or snorkeling, official activity restrictions should be the first conditions to check.

Kabira Bay: Glass-bottom boats do not mean permission to swim

Kabira Bay is one of Ishigaki Island’s representative coastal destinations. Official tourism information identifies glass-bottom boats as an activity for viewing local underwater scenery, while explicitly stating that swimming and snorkeling are prohibited at the nearby beach. These are different ways to experience the bay and must be treated separately when planning.

What you want to do Official Kabira Bay information How to interpret it
Enjoy views of the bay Coastal scenery is listed as a feature Kabira Bay can be included in a sightseeing-focused itinerary
Take a glass-bottom boat Listed as a local activity Viewing underwater scenery from a boat does not grant permission to enter the water yourself
Swim at the nearby beach Swimming is prohibited Do not plan to swim there
Snorkel at the nearby beach Snorkeling is prohibited Do not plan to snorkel there

Even if travelers want to include different marine activities while on Ishigaki, they need to choose viewpoints, boat activities and permitted swimming locations separately, rather than treating every coastal attraction as a place where they may enter the water freely.

Beaches with facilities and designated swimming areas

The official Ishigaki tourism description identifies Maesato Beach as an example of a beach with lifeguards and several facilities. However, this does not mean all services are available every day at all times, or that swimming is appropriate everywhere along the beach.

What to check Official guidance How to apply it
Beach facilities Official information describes Maesato Beach as having lifeguards and several facilities Check the services and opening status for the travel season and day
Swimming location Swim only in designated swimming areas Do not assume a sandy shoreline means entering the water is allowed
On-site supervision Follow lifeguard instructions Follow notices and instructions in effect that day
Currents Official safety information warns about currents Assess sea conditions and swimming-area restrictions before starting an activity

If the main aim is a glass-bottom boat, see Kabira Bay scenery and activity restrictions. If the aim is to enter the water, read Snorkeling and sea-condition safety in Okinawa’s islands first.

Things to remember

These beach categories come from official tourism information and safety guidance. The page does not treat unlisted beaches as confirmed swimming locations or estimate driving times between attractions or individual boat departure times. Beach services, lifeguard arrangements and sea conditions may change, so check official websites and local notices again before departure.
