While **Okunoshima** is famous for its history and its “cute” inhabitants, it is first and foremost a stunning National Park in the **Seto Inland Sea**. The island’s ecology is a fascinating example of how nature can reclaim a once-industrial site. Beyond the rabbits, the island offers emerald waters, pine-scented forests, and a unique coastal environment where the rhythm of the tides dictates the pace of life.
For nature lovers, Okunoshima is a place to observe wildlife behavior in a setting that feels remarkably undisturbed.
**Quick Take**: To truly appreciate the island’s ecology, I highly recommend the [Nature & Wildlife Private Concierge](VIATOR_LINK). A guide can explain the unique flora of the Setouchi region and help you observe natural rabbit behaviors—like the “Binky” and grooming rituals—that casual visitors often miss.

Observing Rabbit Behavior
🎯 **Beyond the Feeding?**
If you sit quietly for 10 minutes without offering food, you will see the rabbits’ true nature.
1. **The Binky**: A high-speed jump and twist in the air—a sign of pure joy.
2. **Grooming**: Watching rabbits meticulously clean their long ears and paws is a lesson in animal hygiene.
3. **Burrows**: Look for the small holes in the ground near the bushes. These are the rabbits’ homes, hand-dug to protect them from the summer heat and winter cold.

**Insider Tip**: Head to the **beaches on the western side** of the island. Here, you can see the rabbits interacting with the sandy environment. It is a surreal sight to see a rabbit hopping along a beautiful, white-sand beach with the blue Seto Inland Sea as a backdrop—a “Tropical Bunny” aesthetic that is unique to Okunoshima.

The Seto Inland Sea Ecosystem
Okunoshima is part of a delicate marine environment. From the island’s northern cliffs, you can often see the swirling currents of the Seto Inland Sea, which are among the strongest in Japan. These currents bring nutrient-rich water that supports a vast array of marine life, including the famous Setouchi octopus and sea bream. The island acts as a sanctuary for sea birds that prey on this abundance.
