The Ultimate Guide to Okunoshima: A Magical Rabbit Island Day Trip from Onomichi and Hiroshima

Tucked away in the sparkling blue waters of Japan’s Seto Inland Sea lies a destination that feels like it was plucked straight from a surreal dream. Okunoshima, more famously known as *Usagi Shima* or Rabbit Island, is a small patch of land where hundreds of wild, fluffy rabbits roam free, eagerly greeting visitors in exchange for a few pellets of food. For travelers exploring the Hiroshima Prefecture or cycling the famous Shimanami Kaido from Onomichi, a day trip to Okunoshima is often the highlight of their Japanese adventure.

However, there is more to this island than just long ears and twitching noses. Okunoshima carries a poignant “Jekyll and Hyde” personality; while the surface is a paradise of cuteness, its soil holds the remnants of a dark, secret history as a chemical weapons manufacturing site during World War II. Today, the island serves as a powerful symbol of peace and resilience. Whether you are a wildlife lover, a history buff, or a photographer seeking the perfect shot of the Setouchi sunset, this comprehensive guide will provide everything you need to plan an unforgettable 2026 trip to Okunoshima.

1. Getting There: How to Reach Rabbit Island from Onomichi and Hiroshima

Navigating the Japanese rail and ferry system is remarkably efficient, but reaching Okunoshima requires a bit of coordination. The island is located off the coast of Takehara City, and the primary gateway is **Tadanoumi Port**.

From Hiroshima City

If you are based in Hiroshima, the easiest way to reach the island is via the JR Kure Line. Take the Shinkansen (Bullet Train) from Hiroshima Station to **Mihara Station** (about 25 minutes). At Mihara, transfer to the local JR Kure Line heading toward Hiro or Takehara and get off at **Tadanoumi Station** (about 20 minutes). From the station, it is a short, well-marked five-minute walk to the Tadanoumi Ferry Terminal.

From Onomichi

For those staying in the charming hillside town of Onomichi, you have two main options. You can take the local JR Sanyo Line to Mihara and follow the steps above. Alternatively, during peak tourist seasons in 2026, keep an eye out for the direct “Rabbit Line” high-speed boat that occasionally operates directly from Onomichi Port to Okunoshima on weekends and holidays. This scenic 45-minute boat ride offers stunning views of the Seto Inland Sea bridges.

The Ferry Experience

Once at Tadanoumi Port, you must purchase your ferry tickets from the vending machines inside the “Rabbit Cafe” gift shop. A round-trip ticket costs approximately 720 yen for adults. While waiting, this is your last chance to buy high-quality rabbit feed (pellets), as **no food is sold on the island itself**. The ferry ride takes about 12 to 15 minutes, docking at either the No. 1 or No. 2 pier on Okunoshima.

2. The Golden Rules of Rabbit Etiquette: Feeding and Interaction

The rabbits on Okunoshima are wild, yet they have become incredibly accustomed to humans. To ensure their safety and yours, there are strict local guidelines that every visitor must follow.

What to Feed (and What Not to Feed)

The best thing to give the rabbits is the dried pellet food sold at Tadanoumi Port. If you want to bring fresh snacks, **carrots and cabbage** are the only human-grade vegetables recommended. However, you should slice them into thin sticks or bite-sized pieces beforehand.

**Never feed them:** Bread, crackers, fruit, or processed human snacks. These can cause fatal digestive issues for rabbits.

**Water:** There are several water bowls scattered around the island. If you see one that is empty, feel free to refill it from the public taps.

Safety and Handling

As tempting as it is, **do not pick up or cuddle the rabbits**. They are fragile animals; dropping them can easily break their backs or legs. Furthermore, being lifted is terrifying for a prey animal. Instead, crouch down or sit on the ground, and they will naturally hop into your lap or surround your feet.

**Avoid the roads:** Do not lure rabbits onto the paved roads or the bicycle paths.

**Hand Hygiene:** Rabbits have sharp teeth and may accidentally nip your finger if they mistake it for a carrot. Always wash your hands after feeding them at the various stations provided.

3. Beyond the Fluff: Exploring the Dark History of “The Poison Gas Island”

While the rabbits are the main draw, the island’s historical significance is profound. From 1929 to 1945, Okunoshima was so secret that it was literally erased from Japanese maps. It was the site of a massive chemical weapons plant that produced mustard gas and tear gas.

The Poison Gas Museum

To truly understand the island, a visit to the **Poison Gas Museum** is essential. The entry fee is nominal (around 150 yen), and it houses a sobering collection of artifacts, photographs, and testimonials. The museum focuses on the “Power of Peace,” detailing the suffering of both the plant workers and the victims of the weapons. It is a quiet, reflective space that provides a necessary counterweight to the lighthearted nature of the rabbit encounters.

The Ruins of War

As you hike or cycle around the island, you will encounter the skeletal remains of the island’s industrial past. The most striking is the **Power Plant ruins** near the ferry pier. This massive, vine-covered concrete structure looks like something out of a Studio Ghibli film. You will also find various ammunition bunkers, laboratory foundations, and the remains of a lighthouse. These sites are fenced off for safety, but they offer incredible photographic opportunities and a hauntingly beautiful aesthetic.

4. Activities and Island Exploration: Cycling and Hiking

Okunoshima is roughly 4 kilometers (2.5 miles) in circumference, making it the perfect size for a leisurely exploration on foot or by bike.

Renting a Bicycle

Upon arrival, head to the **Kyukamura Okunoshima Resort** (the only hotel on the island). They offer bicycle rentals by the hour or for the full day. An electric-assist bike is highly recommended if you plan to head to the island’s highest point, as the inclines can be surprisingly steep. Cycling allows you to reach the quieter parts of the island where the rabbits are less “spoiled” by tourists and more likely to interact gently.

The Observation Deck

For the best views in the Setouchi region, follow the hiking trail up to the **northern observation deck**. On a clear day in 2026, you can see the sprawling bridges of the Shimanami Kaido and the countless emerald islands dotting the sea. This area is also home to a different “vibe” of rabbits—they are often found lounging in the shade of the trees near the summit.

The Beaches

During the summer months, the island’s small beaches are open for swimming. The water is remarkably clear and calm. Even if you aren’t swimming, the coastal boardwalks offer a peaceful stroll with the sound of lapping waves and the occasional “thump-thump” of a rabbit hopping past.

5. Practical Planning: Amenities, Food, and Timing

To make the most of your day trip, you need to be prepared for the island’s limited infrastructure.

Where to Eat

The **Kyukamura Okunoshima Resort** operates a restaurant and a small cafe. The “Usagi Chu” cafe serves themed snacks, including rabbit-shaped ice cream and curry. For a more substantial meal, the hotel buffet offers local Setouchi seafood. However, during busy weekends, the wait times can be long. Many savvy travelers choose to buy a *bento* (lunch box) at Mihara or Onomichi Station and enjoy a picnic at one of the many tables on the island—just be prepared to defend your lunch from curious bunnies!

Best Time to Visit

**Seasonality:** Spring (late March to May) is arguably the best time. The weather is mild, the cherry blossoms may be in bloom, and you are likely to see baby rabbits (kits). Autumn (October to November) is also excellent for hiking.

**Time of Day:** Rabbits are crepuscular, meaning they are most active at dawn and dusk. If you take the first ferry of the morning (usually around 7:40 AM), you will find the rabbits at their hungriest and most energetic.

**Crowds:** Avoid Japanese public holidays and “Golden Week” if possible, as the island can become quite crowded, and the rabbits often get “fed out” by midday, retreating to the bushes for naps.

FAQ: Frequently Asked Questions About Rabbit Island

Q: Where do the rabbits actually come from?

A: There are many legends. Some say they are descendants of the test subjects from the poison gas era, but those animals were unfortunately euthanized when the plant closed. The most likely story is that a group of schoolchildren released eight rabbits on the island in 1971. With no natural predators (cats and dogs are banned) and a high reproduction rate, the population exploded to the hundreds we see today.

Q: Can I stay overnight on the island?

A: Yes! The **Kyukamura Okunoshima** is the only accommodation on the island. Staying overnight allows you to experience the island after the last ferry leaves, which is when the rabbits are most active. The hotel also features an *onsen* (natural hot spring) with views of the ocean.

Q: Are there lockers for my luggage?

A: There are a few coin lockers at Tadanoumi Port and at the Kyukamura hotel on the island. However, they are limited in size. If you have large suitcases, it is highly recommended to leave them in a locker at Mihara or Hiroshima Station before heading to the port.

Q: Is the island wheelchair or stroller accessible?

A: The main loop road around the island and the path to the hotel are paved and relatively flat, making them accessible. However, the hiking trails to the observation deck and the ruins are steep and have stairs, which would be difficult for wheelchairs.

Q: How much money should I bring?

A: Japan is increasingly card-friendly, but for the ferry and the local bus/trains, cash is still king. Expect to spend around 4,000–6,000 yen per person for the day, covering transport from Hiroshima, ferry tickets, lunch, and plenty of rabbit food.

Conclusion: Tips for a Seamless Trip

Okunoshima is more than just a “tourist trap” for cute photos; it is a place of remarkable contrasts. To ensure your 2026 trip goes smoothly, remember to check the ferry schedule in advance, as it changes slightly between the summer and winter seasons. Always carry a small bag for your own trash, as there are very few bins on the island to prevent the rabbits from eating plastic.

If you are coming from Onomichi, consider combining your Rabbit Island trip with a half-day exploration of the **Takehara Preserved District**, often called “Little Kyoto,” which is just one train stop away from Tadanoumi. This allows you to balance the natural whimsy of the island with traditional Edo-period architecture.

By visiting with a spirit of respect—both for the animals and the island’s somber history—you will find that Okunoshima offers one of the most unique and emotionally resonant experiences in all of Japan. Pack your camera, buy an extra bag of pellets, and get ready for a day of fluffy encounters in the heart of the Seto Inland Sea.
