Walk Among Ancient Spirits on the Nakahechi Trail
You’ll discover why pilgrims have walked this sacred path for over 1,000 years when you step onto the Nakahechi section of the Kumano Kodo.
This ancient trail winds through misty mountain forests where every stone seems to whisper stories of emperors, monks, and samurai who once traveled this very route.
The trail stretches 38 kilometers through the Kii Peninsula, but you don’t need to tackle it all at once – strategic overnight stays in traditional ryokan allow you to break the journey into manageable segments.
You’ll encounter massive cedar trees that have stood sentinel for centuries, their gnarled branches creating natural cathedral ceilings above the moss-covered path.

Traditional tea houses still operate along certain sections, offering weary travelers warm meals and cold drinks just as they did hundreds of years ago.
You’ll sleep in pilgrim lodges where tatami mats and sliding paper doors transport you back to feudal Japan, while the sounds of nature provide the perfect soundtrack for deep, restorative sleep.
The trail culminates at Kumano Hongu Taisha, one of Japan’s most sacred Shinto shrines, where you can participate in purification rituals and receive an official completion certificate.
Modern amenities blend seamlessly with ancient traditions – GPS coordinates mark the route while English signage helps international adventurers navigate without losing the mystical atmosphere.

Cuddle With 1,000 Wild Rabbits on Okunoshima Island
You’ll think you’ve entered a real-life fairy tale when hundreds of adorable wild rabbits hop directly toward you on this small island in the Inland Sea.
Okunoshima earned its nickname “Rabbit Island” from the surprisingly large population of European rabbits that now call this 700-meter-wide island home.
The rabbits show no fear of humans, often approaching visitors for pets and treats, creating photo opportunities that will make your social media followers incredibly jealous.
You can reach the island via a 12-minute ferry ride from Tadanoumi Port, and the journey itself offers stunning views of the Seto Inland Sea’s countless small islands.
Beyond the rabbit encounters, the island holds a darker history as a former chemical weapons production site during World War II, with ruins and a poison gas museum providing sobering historical context.
You’ll explore abandoned buildings and bunkers scattered throughout the island’s forests, creating an intriguing contrast between the cute rabbits and the serious historical significance.
The island’s hiking trails lead you through bamboo groves and along coastal paths where you can spot seabirds and enjoy peaceful ocean views between rabbit photo sessions.
A small resort hotel on the island allows overnight stays, giving you the unique experience of having the rabbits mostly to yourself during early morning and evening hours.
The island’s camping grounds provide budget-friendly accommodation options, and you’ll wake up to rabbits grazing just outside your tent in the morning mist.
You can rent bicycles at the port to explore the island’s paved roads, though you’ll need to stop frequently as curious rabbits often block the path.

Explore the Apocalyptic Ruins of Gunkanjima Battleship Island
You’ll step into what feels like a post-apocalyptic movie set when you land on Gunkanjima, an abandoned concrete island that once housed 5,000 people in the world’s most densely populated city.
This eerie island earned its nickname “Battleship Island” because its distinctive silhouette resembles a warship floating on the horizon when viewed from the mainland.
The island served as an underwater coal mining facility for nearly 100 years until operations ceased in 1974, leaving behind a perfectly preserved time capsule of mid-20th century industrial Japan.
You’ll marvel at the towering concrete apartment buildings that still stand today, their empty windows staring out like hollow eyes across the choppy waters of Nagasaki Bay.
The island’s infrastructure remains largely intact, including schools, hospitals, shops, and even a rooftop garden where residents once grew vegetables in this urban jungle surrounded by ocean.
Guided tours take you through designated safe areas where you can peer into abandoned buildings and imagine the bustling community that once thrived in this isolated location.
The tour guides share fascinating stories about daily life on the island, from children playing on rooftop playgrounds to workers descending deep shafts to mine coal beneath the ocean floor.
You’ll see the island’s defensive walls that protect it from typhoons and rough seas, engineering marvels that allowed this artificial city to survive decades of harsh maritime conditions.
Photography enthusiasts will find endless opportunities to capture hauntingly beautiful images of decay and abandonment, with nature slowly reclaiming the man-made structures.
The boat ride to the island takes about 40 minutes from Nagasaki Port, and you’ll often spot dolphins playing in the ship’s wake during the journey.
Limited tour availability and strict safety regulations mean you’ll need to book well in advance, especially during peak seasons when this UNESCO World Heritage site attracts international visitors.
The entire experience lasts about three hours, but the memories of walking through this real-life ghost town will stay with you long after you return to the mainland.
