Yonaguni Marathon

Yonaguni's main aboveground sight of any interest is the marker for the westernmost point of Japan (日本最西端の碑) at the westernmost tip of the island, about a kilometer from Kubura (15 minutes on foot). Despite the marker being located on the island, the official westernmost point of Japan and the closest point to Taiwan is Tuishi (トゥイシ), a rocky reef about 120 m northwest of the shoreline that remains barely above sea level at high tide. It's 107.3 km from there to swim directly across to Wuyanjiao (烏岩角) in Suao, Taiwan.

The kanji mean East Cape, but the reading of the name refers to the rising sun. You can observe it from a cliff. On a clear day, if you're lucky, you can see the coast of Iriomote. Also a grazing area, many Yonaguni horses can be found here.

This cliff near the northern side of Kubura's port offers views of the last sunset in Japan, and on a good day it is possible to see the shadow cast by Taiwan in front of the setting sun from here. This is also the site where, in the rough period when residents of the island were forced to pay an alarmingly expensive head tax after the Ryukyu Kingdom was conquered by the Satsuma clan from the Japanese mainland, pregnant women were sometimes made to jump to their death to avoid an increase in population.

Tindabana is a natural rock formation with a nice view. About 70 m tall. From Tindabana, you can see the entire village of Sonai, and Nandahama. According to tradition, the great empress of Yonaguni, Sanai Isoba, resided here.

Jinmen-iwa is a big rock in the forest that resembles a human face. Requires 12-20 minute hike up the hill by a forest trail. No parking, nearest parking is at Tatigami-iwa.

The "Battleship Rock", about 2 km south of Agarizaki, is a series of peculiarly-shaped reef rock formations. Supposedly, the main rock bears a close resemblance to the shape of a battleship, and that's how it got its name. It can be observed from Sanninudai.
