Shikinejima Family Hotels: Shallow Beaches & Seaside Hot Springs

A small Izu Islands getaway reached by boat from Tokyo — families can enjoy the calm, shallow Tomari Beach and swimsuit-friendly seaside hot springs

Shikinejima is a small island in the Izu Islands chain, part of Tokyo Metropolis, floating just southwest of Niijima. With a coastline of only about 12 km, its jagged, ria-type shore is dotted with shallow, calm-watered beaches, making it a perfect island for playing in the sea with kids. It's about a 3-hour ride from Takeshiba Pier in Tokyo by high-speed jet boat (a large ferry is also available), or just about 15 minutes by connecting boat from Niijima. You can also get there via Niijima from Chofu Airport.

The island's biggest draw is a sea that's safe for kids to play in. Tomari Beach, set in a round cove, has extremely calm waves and a shallow, gently sloping shore, making it perfect for a child's first time swimming in the ocean. There's also Nakanoura Beach for snorkeling and Ishijirokawa Beach near the village, and thanks to the island's small size, you can walk to the beach right from your hotel.

Another local specialty is the free hot springs you can soak in while wearing your swimsuit. Jinata Onsen, a hidden spring where the water temperature shifts with the tides, the seaside open-air Matsugashita Gayu, and Ashitsuki Onsen, shallow enough for kids to enjoy, all let you combine a soak in a natural hot spring with your beach time. All of them are free and open 24 hours, so families can enjoy the feel of a hot spring hopping tour.

Places to stay are mostly homey family-run inns, ryokan, and guesthouses. Home-cooked meals at fisherman's inns made with fresh fish and island vegetables, plus homemade tokoroten (a local seaweed jelly), are part of the island's food culture. With beautiful starry skies and plenty of room for kids to roam free in nature, it's an island that's gentle on families traveling together.

Travel tips

You can reach the island by high-speed jet boat, large ferry, or a connecting boat from Niijima, arriving mostly at Nobushi Port. The island is small enough to get around on foot or by rental bicycle. Because the seaside hot springs' accessible hours shift with the tide, it's reassuring to check the tide chart before you go. Confirm the swimming season for the beaches, and take heatstroke precautions in summer. Some family-run inns only take reservations by phone, so plan ahead.
