Oshima Palais La Mer by Bus Guide

Palais La Mer is a small shell museum on the south side of Izu Oshima, useful for travelers who like specialist local museums and bus-based island routes. For now, the first planning point is simple: check the closure notice before you build it into a day trip.

Current Closure First

As checked on August 21, 2026, Oshima Town’s official notice says Palais La Mer is temporarily closed for lighting-equipment renovation work from May 7, 2026, to March 31, 2027, planned. Do not plan a paid museum visit during that period unless the town posts a new reopening notice.

This guide is still useful as a route note for reopening planning, for confirming the correct bus line, and for understanding where the museum fits into a Habu Port Line day.

What Palais La Mer Is

The official Tokyo travel guide uses the English-facing name Palais La Mer and describes it as a museum of shells and shellfish fossils. Oshima Town’s facility page says the museum is inside the Oshima Town Workers’ Welfare Hall in the Sashikiji Kudacchi area.

Oshima Town describes displays including shells from around the world, bivalves, gastropods, shell fossils, and shell folk crafts. It is a niche museum, so it works best for travelers who enjoy small local collections rather than large-city museum scale.

Bus Access

Oshima Bus’s sightseeing page lists Palais La Mer on the Habu Port Line, with the stop shown as Palais La Mer-mae and the walk from the stop as 0 minutes. Oshima Town’s facility page lists access by getting off at Kinro Fukushi Kaikan-mae. Treat those as the stop-name details to verify on the current official route map and timetable before boarding.

Use Oshima Bus’s route-bus page for live planning. As checked on August 21, 2026, the posted timetable period was July 1 to September 30, 2026, and the page linked the route-bus timetable and island map, the Habu Line summary timetable, the route map, fare table, and riding guide. Do not copy an old departure time into your plan.

Hours, Admission, And Reopening Checks

The standing facility information lists hours as 9:00 to 17:00 and admission as 400 yen for adults and 200 yen for elementary and junior-high students, with a note that fees may change and should be confirmed in advance. GO TOKYO’s English page also lists general admission as 400 yen cash and tells visitors to check updated details with the official website or facility.

Because the temporary closure notice is newer than the standing facility page, the closure notice should control your 2026-2027 planning. Before publishing a route in your own itinerary, check the Oshima Town facility page, the temporary-closure page, and the museum or town contact information.

How To Use It In A Habu Port Line Day

After reopening, Palais La Mer can be paired with other south-side stops on the Habu Port Line, especially if you are already planning Habu Port, Fudeshima, Toshiki Coast, or other nearby bus stops. The museum is indoor, compact, and weather-resilient, so it can balance a day that otherwise depends on coastal conditions.

During the closure, do not make the museum the anchor of the route. If you pass the area by bus, use it only as a location reference and keep your main plan around open stops, confirmed shops, or coastal viewpoints.

Fare And Payment Planning

Oshima Bus’s official route-bus page listed one-day passes at 2,500 yen for adults and 1,250 yen for children, and two-day passes at 3,800 yen for adults and 1,900 yen for children, valid on all routes, as checked on August 21, 2026. A pass may be useful if Palais La Mer is one stop in a multi-stop island day after reopening.

Oshima Bus’s FAQ says Suica and PASMO are not accepted, while cash and PayPay are accepted. The FAQ also says on-bus change is available for 50 to 500 yen coins and 1,000 yen notes. Carry small cash for both buses and museum-style admission planning.

Before You Go Checklist

  • Check whether the temporary closure notice has changed.
  • Use Oshima Bus’s current route-bus page for the Habu Line timetable.
  • Verify the stop name on the latest route map before boarding.
  • Carry small cash; do not assume IC transit cards work on Oshima Bus.
  • If the museum is still closed, replace it with another confirmed Habu Port Line stop.
