Haterumajima Astronomical Observatory Tower, Astronomical observatory on Hateruma Island, Japan
The Haterumajima Astronomical Observatory Tower stands on the southern edge of Japan, featuring a 20mm refracting telescope for night sky observation.
The observatory was built to provide scientific observations from Japan's southernmost inhabited island, where traditional seafaring navigation relied on celestial guidance.
Local astronomers share their knowledge of constellations visible from this latitude, including the Southern Cross visible between December and June.
The facility operates from 10:00 to 17:00 and evening hours vary by season, with admission fees of 400 yen for adults and 200 yen for children.
The minimal light pollution and geographical position at 24 degrees north latitude enable clear views of both northern and southern hemisphere constellations.
