Overview
Kohama Island (小浜島) is a small, lush island in the Yaeyama archipelago of Okinawa Prefecture, southwestern Japan. It sits roughly between Ishigaki Island to the northeast and Iriomote Island to the west, covering only about 8 square kilometers. The island is home to a few hundred permanent residents and retains a genuinely quiet, agricultural character — sugarcane fields dominate the interior, and the pace of life is notably unhurried.
The island gained a degree of wider recognition in Japan after the 2001 NHK drama Churasan, which was filmed here and sparked domestic tourism interest. Despite that attention, Kohama has not developed into a crowded resort destination. Its appeal remains rooted in natural scenery: coral-fringed shorelines, shallow turquoise lagoons, and the sweeping ocean views visible from its gentle hills.
Visitors typically come for the beaches, snorkeling, and the opportunity to experience a rural Okinawan island without heavy tourist infrastructure. The island is small enough to explore meaningfully in two to three days, though some travelers choose to base themselves here while making day trips to Iriomote or Ishigaki.
Before You Go
Visas
Japan has visa exemption agreements with many countries, but entry requirements can change. Do not rely on secondhand information — check TravelerPulse's Visas section and confirm current rules with Japan's Ministry of Foreign Affairs (mofa.go.jp) before you travel.
Health & Vaccinations
No specific vaccinations are required for Japan. Travelers should ensure routine immunizations are up to date. Note that Okinawa's subtropical climate means mosquitoes are present, particularly near mangroves and wetland areas on neighboring Iriomote. Bring repellent if you plan to spend time outdoors in the evening.
What to Pack
- Reef-safe sunscreen (conventional chemical sunscreens are harmful to the coral ecosystems here and their use is discouraged at many local beaches)
- Snorkeling gear (available to rent locally, but bringing your own guarantees fit and condition)
- Lightweight, breathable clothing; a light layer for air-conditioned ferries and vehicles
- Cash — card acceptance on small islands can be limited; verify locally
- Japanese phrasebook or translation app, as English signage and English-speaking staff are limited outside resort facilities
Getting There
Kohama Island is reached by ferry from Ishigaki Island (石垣島), which serves as the main transportation hub for the Yaeyama group. Ishigaki New Airport (ISG) receives flights from Tokyo (Haneda and Narita), Osaka, Naha, and other Japanese cities. There are no international flights directly to Ishigaki; travelers arriving from abroad typically connect via Tokyo or Osaka.
From Ishigaki's離島ターミナル (離島フェリーターミナル, 離島Terminal /離島Pier), high-speed ferries operate to Kohama. The crossing takes approximately 25–30 minutes. Ferry operators serving this route have included Anei Kanko and Yaeyama Kanko Ferry, among others — verify current schedules, fares, and operators directly at the terminal or on the operators' official websites, as these change seasonally.
There is no airstrip on Kohama Island itself. All access is by sea. The Kohama ferry terminal is a small facility; transport onward into the island should be arranged in advance, especially outside peak season when options may be limited.
Getting Around
Kohama Island is small enough that most visitors get around by bicycle or scooter, both of which are typically available to rent near the ferry terminal. Cycling is a practical and popular way to explore the island's interior roads, sugarcane fields, and coastal viewpoints, though the terrain does include some modest hills.
The island's single main resort (Haimurubushi) operates its own shuttle service for guests; independent travelers should not assume access to this. A small number of taxis may be available — verify locally on arrival. There is no public bus network to speak of.
Roads are narrow and traffic is light. Drivers should be mindful of local agricultural vehicles and pedestrians, and note that Japan drives on the left.
Where to Stay
Accommodation options on Kohama Island are limited, which is part of the island's character. The most prominent property is Haimurubushi (はいむるぶし), a resort-style facility with beach access, swimming pools, and on-site dining. It is well regarded and tends to book up during peak season (summer holidays, Golden Week, and Obon); reserve well in advance.
Beyond the main resort, a small number of guesthouses (民宿, minshuku) and vacation rentals exist on the island. These offer a more immersive local experience but facilities are simpler. Availability and current operators should be confirmed through booking platforms or by contacting Okinawa tourism resources directly, as small properties on remote islands can open and close.
If accommodation on Kohama itself is unavailable or limited, many travelers choose to base themselves on Ishigaki and visit Kohama as a day trip, which is entirely feasible given the short ferry crossing.
Things to See & Do
Beaches and Snorkeling
Kohama's beaches are its primary draw. Hateno-hama (幻の島 / Phantom Island) is technically a sandbar accessible by boat tour from Kohama or Ishigaki rather than a beach on the island itself, but tours commonly depart from this area. The waters around Kohama have healthy coral systems and are popular for snorkeling and glass-bottom boat tours. Sea kayaking is another common activity.
Cycling the Island
A circuit of the island by bicycle passes through fields of sugarcane, small fishing hamlets, and elevated points offering panoramic views over the surrounding ocean toward Iriomote and Taketomi. The Shugaren viewpoint area is often cited as one of the better vantage points on the island — verify access conditions locally.
Slower Pursuits
Kohama rewards visitors who slow down. Watching the sunset from the western shoreline, exploring the small local settlement on foot, and simply sitting by the water are experiences as valid as any organized activity. Star-gazing is notably good here due to minimal light pollution.
- Snorkeling and marine tours
- Sea kayaking
- Cycling
- Sunset and star-gazing
- Day trips to Iriomote (mangrove canoe tours, jungle trekking) and Taketomi (traditional Ryukyuan village)
Food & Drink
Dining options on Kohama Island are modest. The Haimurubushi resort has its own restaurant facilities. Outside the resort, there are a small number of local eateries in the island's residential area, though hours and availability should be verified locally — it is not uncommon for small island restaurants to close unexpectedly or operate only at certain times.
Local Okinawan cuisine is worth seeking out wherever possible. Look for dishes such as goya champuru (bitter melon stir-fry), rafute (braised pork belly), soki soba (Okinawan noodle soup with spare rib), and fresh seafood. Orion Beer is the ubiquitous local lager of Okinawa and widely available.
Travelers with dietary restrictions or specific needs are advised to bring some supplies from Ishigaki, where supermarkets and convenience stores provide a broader range of options. Do not assume convenience store access on Kohama — confirm what is available before arrival.
Practical Information
Money
Cash is strongly recommended. ATM access on the island is very limited; withdraw sufficient yen on Ishigaki before taking the ferry. Verify current ATM availability locally.
Connectivity
Mobile data coverage exists on the island via major Japanese carriers, though it may be intermittent in some areas. Pocket Wi-Fi devices, which can be rented at Japanese airports, are a reliable option for travelers needing consistent connectivity.
Emergency Numbers
In Japan, dial 110 for police and 119 for fire and ambulance services. These numbers function nationwide. For medical emergencies on remote islands, evacuation to Ishigaki or mainland Okinawa may be required — travel insurance that covers medical evacuation is strongly recommended.
Travel Insurance
Given the island's remoteness and limited medical facilities, comprehensive travel insurance including medical evacuation coverage is not optional — it is sensible.
Waste and Environment
Kohama, like many of Japan's smaller islands, has limited waste infrastructure. Pack out what you bring where possible, use reef-safe sunscreen, and respect marine conservation guidelines communicated by local operators.
Safety
Kohama Island is generally very safe. Crime rates in rural Okinawa are low, and visitors are unlikely to encounter security concerns. The primary risks are environmental.
Ocean conditions can change quickly, particularly during and after typhoons. Swimming and snorkeling outside of designated areas or after weather warnings is strongly discouraged. The habu jellyfish (Chironex and related species) and the habu snake are present in Okinawa's natural environments — both warrant caution, though encounters on beaches are uncommon. Follow guidance from local operators regarding safe snorkeling areas.
Typhoon season runs roughly from July through September. Typhoons can cause ferry cancellations and strand travelers on the island for several days. Build flexibility into your itinerary if visiting during this period, and monitor Japan Meteorological Agency (jma.go.jp) forecasts.
Local Culture & Etiquette
Kohama Island is part of the Yaeyama cultural sphere, which has distinct traditions, music, and historical roots that differ from both mainland Japan and even central Okinawa. The Ryukyuan heritage of the region is expressed in local festivals, the architecture of older buildings, and traditional performing arts including Yaeyama folk music and dance.
The island's community is small and tightly knit. Visitors should conduct themselves respectfully in residential areas, keep noise to a minimum in the evenings, and ask permission before photographing local residents or private property. These courtesies matter more on small islands where tourism and daily life exist in close proximity.
Some local festivals take place through the year according to the lunar calendar; dates vary annually. If cultural events are a priority, contact the Yaeyama Tourism Association or local accommodation in advance to find out whether any festivals coincide with your visit.
