Hateruma Island | Japan's Southernmost Inhabited Isle, Nishihama, Southern Cross, Ferry & Access

The sea of “Hateruma Blue,” praised as “Japan’s most beautiful sea”; the star-filled sky you look up at on Japan’s southernmost inhabited island; Nishi-hama with its exquisite white sand and emerald green—“Hateruma Island” is an ultimate paradise that radiates a special presence even within the Yaeyama Islands.

“Hateruma” is an island name meaning “the coral reef at the end.” On this subtropical southern island near the Tropic of Cancer, you can observe the Southern Cross, never visible on Honshu. Access is somewhat difficult (a 40–70-minute high-speed boat where seasickness is inevitable), but it’s a special island definitely worth visiting by overcoming that. In this article, we’ll fully cover Hateruma Island’s charm, highlights and access.

What Kind of Island Is Hateruma Island? Japan’s Southernmost Inhabited Island

Hateruma Island is Japan’s southernmost inhabited island. Belonging to Taketomi Town, Yaeyama District, Okinawa, it’s a small island of about 12.77 km² in area with a population of about 500. Its latitude is 24°2′ N—the inhabited island of Japan closest to the equator, truly the “island at the end.”

The island’s name derives from “Hate-no-Uruma (the coral island at the end).” That it’s a special island floating on the endlessly spreading coral-reef sea at the southern edge of the Yaeyama Islands is expressed in its name too.

The blueness of the sea praised as “Hateruma Blue”

Hateruma Island’s sea is characterized by a distinctive deep blue called “Hateruma Blue.” Its transparency is astounding—so clear you can see the seabed even at depths over 10 m. Travelers who rate it “Japan’s most beautiful sea” are endless.

Hateruma Island’s Highlights

Nishi-hama (Kita-hama) | Japan’s best superb-view beach

Hateruma Island’s biggest highlight is Nishi-hama (Kita-hama). The beach where you can experience “Hateruma Blue” most beautifully, its white-sand long beach and emerald-green gradation are a superb view among superb views. The nice point is that you can encounter sea turtles at a high rate while snorkeling too.

The southernmost-point monument | a commemorative photo spot

At the island’s southern tip, along the coast of Takanazaki, is the “Japan’s Southernmost Point Monument.” A symbol where you can feel having reached the southern tip of Japan’s inhabited islands—an absolutely must-visit commemorative photo spot.

The Southern Cross | a constellation invisible on Honshu

Hateruma Island is a mecca for observing the Southern Cross. Owing to the latitude, you can observe the Southern Cross low in the sky around December–June. At the island’s “Stargazing Observation Tower,” you can do full-on stargazing (open at night only).

Pemuchi-hama | a quiet hidden-gem beach

Pemuchi-hama, located in the island’s southeast, is a hidden-gem beach with few tourists. A spot with a mysterious atmosphere where rough waves, reefs, and a superb Pacific view spread out.

The awamori island | Awanami

The awamori made on Hateruma Island, “Awanami,” is a rare brand known as “phantom awamori.” A gem with low production and hard to obtain. There’s also island-limited awamori you can only get on Hateruma Island, so it’s ideal as a souvenir.

“A hard-to-reach island” | a high cancellation rate

Hateruma Island is an island with a very high cancellation rate. Because boats easily get cancelled when sea conditions are rough, it’s also called “the island you want to go to but can’t.” Build a schedule with room to spare into your travel plan, and be sure to check the operation information the morning of.

Getting around the island by rental bicycle

Getting around the island is convenient by rental bicycle (electric recommended) or rental bike. On foot it takes too long, and the sun is merciless, so getting around by bicycle is realistic.

Cautions When Visiting Hateruma Island

Measures against cancellation risk

There are cases where “the outbound boat departed, but the return boat is cancelled and you’re stuck on the island.” A schedule with room for 1–2 nights, or securing accommodation, is desirable.

Seasickness measures

The high-speed boat rocks a great deal. The tricks: take motion-sickness medicine by 30 minutes before departure, avoid an empty or full stomach, and look outside from a window seat.

Few convenience stores & ATMs

There are no convenience stores on the island. There’s only a post-office ATM, so prepare plenty of cash on Ishigaki.

Light-source measures during stargazing

When observing the Southern Cross, using a red LED flashlight or dimming the light causes less interference with night vision and lets you enjoy a more beautiful starry sky.
