What To Expect
Stop 1
⏱ 1h 30mYour journey to Sarushima begins with a short but scenic ferry ride from Mikasa Pier in Yokosuka. As you cross Tokyo Bay, the city slowly fades behind you and a sense of adventure takes over. In just 10 minutes, you’ll arrive at Japan’s only natural island in the bay—a place untouched by modern development and rich in history. Once a vital military outpost, Sarushima is now uninhabited, covered in greenery, and filled with remnants of its past. You’ll walk along quiet forest trails, explore moss-covered stone walls, red-brick tunnels, and artillery remains, and enjoy sweeping views of the sea. The island’s peaceful, overgrown ruins often remind visitors of a Ghibli movie scene. With no cars, no residents, and nature slowly reclaiming the land, Sarushima feels like a step back in time. It’s the perfect blend of mystery, beauty, and serenity—just a short boat ride away from the mainland.

【VIP】Geisha Dance ＆ Tea ceremony experence with Yukata
A valuable experience that can only be had in Japan. It's a waste to end up wearing a yukata! Wearing a yukata and bowing and walking, let's feel Japan in the era when there were samurai. Once you get used to wearing a yukata, use a fan to dance to the representative Japanese song "Sakura Sakura".
