The Ultimate Okunoshima Rabbit Island Day Trip Guide: Everything You Need to Know

Tucked away in the sparkling blue waters of the Seto Inland Sea lies one of Japan’s most whimsical yet poignant destinations: Okunoshima, better known to the world as “Rabbit Island.” Imagine stepping off a ferry and being immediately greeted by dozens of twitching noses and floppy ears. For animal lovers and curious travelers exploring the Hiroshima or Onomichi regions, this small island offers an experience unlike any other in East Asia.

As you plan your 2026 journey through the Setouchi region, Okunoshima stands out as the perfect day trip. It combines the sheer joy of animal interaction with the rugged beauty of Japan’s coastal landscapes and a sobering lesson in modern history. Whether you are coming for the “kawaii” photo opportunities or to explore the haunting ruins of the island’s industrial past, this guide provides all the practical details, ethical tips, and local secrets you need to make the most of your visit to this long-eared paradise.

1. Getting to Okunoshima: The Journey from Hiroshima and Onomichi

Reaching Okunoshima requires a bit of planning, as it is located off the coast of Takehara City. The most common gateway is **Tadanoumi Port**.

From Hiroshima City

The fastest way is to take the Sanyo Shinkansen to **Mihara Station** (approx. 25 minutes). From Mihara, transfer to the local **JR Kure Line** headed toward Hiro or Takehara and get off at **JR Tadanoumi Station** (approx. 20 minutes). From the station, it is a well-signed, five-minute walk to the Tadanoumi Ferry Terminal.

From Onomichi

If you are staying in the charming hillside town of Onomichi, the trip is even simpler. Take the JR Sanyo Line to Mihara Station, then follow the same instructions for the JR Kure Line to Tadanoumi. Alternatively, during peak seasons and weekends, there is sometimes a direct scenic ferry (the “Rabbit Line”) that runs from Onomichi Port directly to Okunoshima, though it is more expensive and less frequent than the Tadanoumi route.

The Ferry Experience

Once at Tadanoumi Port, you can purchase ferry tickets from a vending machine inside the “Rabbit Island” gift shop. The ferry ride takes about 15 minutes. **Pro Tip:** The gift shop at Tadanoumi Port is your last chance to buy rabbit food. There is no food for sale for the animals once you arrive on the island.

2. Ethical Interaction: How to Feed and Pet the Rabbits

While the rabbits are accustomed to humans, they are still wild animals. To ensure their safety and your enjoyment, there are strict “Rabbit Rules” that every visitor must follow.

What to Feed

The rabbits’ health depends on a proper diet. The best things to provide are:

**Pellets:** Sold in small bags at the Tadanoumi Port shop.

**Fresh Vegetables:** Cabbage and carrots are favorites. It is highly recommended to chop them into bite-sized sticks before arriving.

**Timothy Hay:** If you are a dedicated bunny fan, bringing high-quality hay is the best thing for their digestion.

**Avoid:** Bread, crackers, human snacks, or fruit in large quantities. These can make the rabbits severely ill.

Safety and Etiquette

**Don’t Pick Them Up:** Rabbits have fragile spines and are easily frightened. If they struggle and fall, it can be fatal.

**Watch the Road:** Rabbits often congregate near the roads because they know tourists arrive there. If you rent a bicycle, ride slowly and keep a sharp eye out for bunnies lounging in the shade.

**Fresh Water is Gold:** While tourists bring plenty of food, fresh water is often scarce. There are several water bowls scattered around the island near the hotel and ruins. If you see one empty, use a public tap to refill it; the rabbits will thank you more for the water than the snacks.

3. The Dark History: Exploring the Poison Gas Museum and Ruins

Beneath the cute surface of Okunoshima lies a “dark tourism” site that offers a profound contrast to the bunnies. From 1929 to 1945, the island was used to secretly manufacture chemical weapons, including mustard gas and tear gas. It was so secret that Okunoshima was actually erased from Japanese maps during that era.

The Poison Gas Museum

For a small entry fee (approx. 100 yen), you can visit the Poison Gas Museum. It is small but impactful, documenting the horrific effects of chemical warfare and the plight of the workers—many of whom were local school children—who were exposed to the toxins. It serves as a stark reminder of the island’s role in WWII and a plea for global peace.

The Ruins

As you hike or bike around the island, you will encounter several haunting concrete shells of the former facilities:

**The Power Plant:** This is the most iconic ruin, a massive, vine-covered structure near the ferry pier. While you cannot enter for safety reasons, the exterior is incredibly atmospheric.

**The Storage Magazines:** Tucked into the hillsides, these stone bunkers were used to store the chemicals.

**The Northern Cannon Battery:** Located at the island’s highest points, these offer a mix of military history and stunning 360-degree views of the Seto Inland Sea.

4. Island Facilities: Where to Eat and Stay

While Okunoshima is a small island, it is well-equipped for visitors thanks to the **Kyukamura Ohkunoshima**, the island’s only hotel and resort hub.

Dining Options

**The Hotel Restaurant:** Offers a buffet lunch and dinner featuring local Setouchi seafood. It is the most reliable place for a full meal.

**Usagi Cafe:** A small, casual cafe inside the hotel building serving coffee, “rabbit-themed” soft-serve ice cream, and light snacks like curry or pasta.

**Picnics:** Many travelers choose to buy a bento box in Mihara or Tadanoumi and enjoy a picnic at one of the many coastal tables. Just be prepared for “uninvited guests” (bunnies) trying to join your meal!

Bicycle Rentals

The best way to see the whole island is on two wheels. The Kyukamura hotel offers bicycle rentals (including electric-assist bikes). The 4km perimeter road is mostly flat and incredibly scenic, making it an easy ride for all ages.

Staying Overnight

For a truly unique experience, consider staying at the Kyukamura hotel. Once the last ferry leaves around 5:00 PM, the island becomes incredibly quiet. This is the best time to see the rabbits at their most active, as they are crepuscular (most active at dawn and dusk). The hotel also features an *onsen* (hot spring) with views of the sea.

5. Planning Your Itinerary: Maximizing Your Day Trip

To get the most out of your visit, timing is everything. A typical day trip takes about 4 to 6 hours.

**09:00 AM:** Arrive at Tadanoumi Port. Buy your rabbit food and ferry tickets.

**09:30 AM:** Take the ferry to the island. Use the free shuttle bus from the pier to the Kyukamura Hotel to drop off heavy bags in a locker.

**10:00 AM – 12:00 PM:** Start your “Rabbit Time.” Walk the paths near the hotel where the bunny population is highest.

**12:00 PM:** Lunch at the Usagi Cafe or a seaside picnic.

**01:00 PM:** Rent a bike and head north. Visit the Poison Gas Museum and the Power Plant ruins.

**02:30 PM:** Hike or cycle to the island’s observation deck at the summit for a panoramic view of the surrounding islands.

**04:00 PM:** Head back to the pier, perhaps stopping for one last feeding session.

**04:30 PM:** Take the ferry back to Tadanoumi.

**Local Recommendation:** If you have extra time in the afternoon, stop by the nearby town of **Takehara**. Its “Preserved District” is known as “Little Kyoto” and features beautifully maintained Edo-period buildings and sake breweries.

6. Best Time to Visit and What to Pack

The experience on Okunoshima changes significantly with the seasons.

**Spring (March – May):** The most popular time. The weather is mild, and you might see baby bunnies (kits). The cherry blossoms on the island add a beautiful pink backdrop.

**Summer (June – August):** It can be very hot and humid. The rabbits tend to hide in the shade or underground during the day, so you may see fewer of them until the sun begins to set.

**Autumn (September – November):** Excellent hiking weather and beautiful fall foliage.

**Winter (December – February):** While it’s cold, this is actually a great time to visit. Food is scarcer in winter, so the rabbits are much more eager to approach humans for snacks.

Packing Checklist:

1. **Hand Sanitizer/Wipes:** You will be touching surfaces and possibly animals; hygiene is key.

2. **Comfortable Walking Shoes:** Even if you rent a bike, there is some light hiking involved to reach the best viewpoints.

3. **Ziploc Bags:** To keep your rabbit vegetables fresh and to carry your trash back (there are very few trash cans on the island to prevent rabbits from eating plastic).

4. **Sun Protection:** The coastal sun can be strong, even in cooler months.
