Kohama Island Travel Guide

Kohama Island (小浜島) is a small inhabited island in Okinawa Prefecture's Yaeyama archipelago, located in the southwestern corner of Japan. The island covers roughly 8 square kilometres and is home to a few hundred permanent residents. Life here revolves around sugarcane farming, fishing, and small-scale tourism.

The island gained wider recognition in Japan after serving as a filming location for the popular NHK drama Churasan in 2001, which brought a gentle wave of domestic visitors. It remains far quieter than nearby Ishigaki or Iriomote, making it a genuine retreat for travelers who want to slow down.

The landscape is low-lying and rural, dominated by sugarcane fields, a single ridge road offering panoramic views of surrounding islands, and fringed by coral-rich coastline. There are no large-scale resorts by the standards of mainland Japan, though a well-known resort property occupies a significant portion of the island's western shore — verify current operations locally.

Visas

Kohama Island is Japanese territory and subject to standard Japanese immigration rules. For current visa requirements specific to your nationality, check TravelerPulse's Visas section and the official Japan Immigration Services Agency website.

Health

No vaccinations are specifically required for travel to Okinawa, but standard travel health precautions apply. The island has no hospital; the nearest medical facilities are on Ishigaki Island. Travel insurance that covers evacuation or ferry transport to Ishigaki is strongly advisable.

What to Pack

• Reef-safe sunscreen (important for protecting the coral ecosystem)
• Insect repellent, particularly if visiting May through October
• Lightweight, breathable clothing year-round; a light layer for December to February
• Cash — card acceptance is limited on small islands; ATMs are scarce, so stock up on Ishigaki

Typhoon Season

The Yaeyama islands sit in a typhoon corridor. Tropical storms can disrupt ferry and air access, sometimes for several days. Travel between roughly June and October carries this risk; monitor Japan Meteorological Agency forecasts.

By Ferry from Ishigaki

The standard approach is to fly into Ishigaki Island (New Ishigaki Airport, ISG) and then take a high-speed ferry to Kohama. Ferries operate from Ishigaki's 離島ターミナル (離島フェリーターミナル,離島 Terminal). The crossing takes approximately 25–30 minutes. Schedules, fares, and operators — primarily Yaeyama Kanko Ferry and Anei Kanko — should be verified on their official websites or at the terminal, as timetables change seasonally.

By Air

There is no commercial airport on Kohama Island itself. Ishigaki is the regional hub, with connections to Naha (Okinawa's main city) and major Japanese airports including Tokyo (Haneda/Narita) and Osaka (Kansai). Naha also connects to some international destinations, though most travelers from overseas will transit through a main Japanese hub.

Practical Note

Last ferries back to Ishigaki typically run in the late afternoon; confirm the final sailing time before planning your day to avoid being stranded.

Kohama Island is small enough that most of it is accessible by bicycle, and cycling is the most common way for visitors to explore. Rental bicycles (including some electric-assist models) are typically available near the ferry pier — availability and pricing should be confirmed locally upon arrival.

Scooter and small car rentals may also be available, though the island's roads are quiet and narrow. A single main road loops around much of the island and climbs to the Shisa Hill viewpoint ridge.

There is no public bus service in the conventional sense. If you are staying at the resort, shuttle transport may be provided — verify with your accommodation. Walking between the pier area and nearby attractions is feasible for shorter distances.

Accommodation on Kohama is limited to a small number of options. The most prominent is a large resort property on the island's western coast; this establishment has historically dominated the island's hospitality offer and includes beach access and dining. Verify current status, availability, and pricing directly with the property or through a reputable booking platform.

Smaller guesthouses (minshuku) may exist and are worth researching through Japanese travel platforms or local tourism boards. These offer a more locally embedded experience, often with home-cooked meals included.

For travelers on tighter budgets or those who prefer a wider range of accommodation and dining options, basing yourself on Ishigaki and making Kohama a day trip is a practical alternative.

Beaches and Snorkeling

Kohama's coastline includes several sandy beaches with access to coral gardens just offshore. Hateno Beach on the eastern side is frequently mentioned by visitors. The surrounding waters are part of the Iriomote-Ishigaki National Park, and the coral biodiversity is high. Snorkeling equipment can typically be rented locally; verify availability at the pier area.

Cycling the Island

Riding the ridge road that runs along the island's central spine offers views across to Iriomote, Taketomi, Ishigaki, and on clear days, distant islands further west. The landscape of sugarcane fields and low hills is representative of Yaeyama rural life.

Shisa Hill (シーサー岩)

A recognizable natural rock formation said to resemble a shisa (the lion-dog guardian figures ubiquitous in Okinawan culture), this viewpoint is a short detour that rewards with broad island panoramas.

Sea Kayaking and Diving

Several operators based in the Yaeyama area run day trips that include Kohama's waters. Diving around the nearby reefs can be arranged through operators on Ishigaki or, seasonally, locally. Confirm what is currently available on the island itself upon arrival.

Churasan Film Locations

For visitors interested in Japanese television history, the rural settings used during filming of the 2001 NHK drama are scattered across the island's sugarcane landscape. Local signage points to some of these spots.

Dining options on Kohama are limited. The island supports a small number of casual restaurants and cafes, primarily near the ferry pier. Expect Okinawan staples such as goya champuru (bitter melon stir-fry), sōki soba (pork rib noodle soup), and fresh seafood. Availability varies by season and day of the week — it is not unusual for small establishments to be closed without advance notice.

If you are staying at the resort, on-site dining is likely your most reliable option, but verify current restaurant offerings directly with the property before arrival.

Stock up on snacks, bottled water, and any specific dietary needs in Ishigaki before making the crossing, as convenience store options on the island are minimal. Habitual coffee drinkers should note that specialty café culture is limited here.

Money

Carry sufficient yen cash before arriving on Kohama. ATM access on the island is unreliable; the post office or convenience stores in Ishigaki's city center are better places to withdraw cash.

Connectivity

Mobile coverage exists but may be patchy in parts of the island. Download offline maps before departure. Wi-Fi is likely available at accommodation but not reliably across the island.

Waste and Environment

Kohama sits within a national park. Take all rubbish back to your accommodation or to Ishigaki. Do not remove coral, shells, or sand — this is prohibited under Japanese law.

Emergency Contacts

Japan's general emergency numbers are 110 (police) and 119 (fire and ambulance). For medical emergencies requiring hospital-level care, evacuation to Ishigaki will be necessary. Confirm the local clinic situation — if any exists — upon arrival.

Language

Very little English is spoken outside resort properties. A translation app and a few basic Japanese phrases will go a long way.

Kohama is a living community, not a theme park. The majority of residents make their living from agriculture (primarily sugarcane) and fishing, and daily rhythms are tied to those industries. Visitors are welcome but the population is small, so considerate behavior matters more here than in large tourist cities.

Okinawan culture broadly — including that of the Yaeyama islands — has its own distinct identity shaped by the Ryūkyū Kingdom's history, which predates Japanese rule. Local traditions, music (sanshin, a three-stringed instrument), and food differ noticeably from the Japanese mainland. Approaching these differences with curiosity rather than assuming uniformity with wider Japan enriches the experience.

When cycling past residential areas or working farms, keep noise down and stay on designated roads. If you are photographing locals or their property, ask first.
