The lighthouse at Kasarizaki is located on the northernmost headland of Amami-oshima and watches ships sailing to and fro. It is shown on the maps as “Kasarizaki Todai (lighthouse)”, but local people call it “Yo-misaki (headland) Todai” because Yo is the closest village to the lighthouse.

Both currents flowing along the west shoreline (facing the East China Sea) and the east shoreline (facing the Pacific Ocean) of Amami-oshima come together off this headland, forming a rapid and strong tide.

A few flights of concrete steps will lead you up to the lighthouse. There you can enjoy a broad view over the ocean. If you look northeast, you will find Tompara Rock, being washed by raging waves, at a short distance. You can make out the faint and flat outlines of Kikaijima Island far off in the east-southeast sea. Ayamaru-misaki is seen far beyond the long Yo-misaki beach.

Yo-misaki Headland is known for its Easter lilies (cf. the article of May, 2008). At the period when Easter lilies bloom, you can also find wild gladioli. Oshima-nojigiku (a species of Chrysanthemum japonese), which live in community, bloom with small white flowers in late fall.
