Celestial Calendar: Top Upcoming Astronomical Events for Japan in 2019

Date published: 5 January 2019

From meteor showers to eclipses to supermoons and more, 2019 is filled with many interesting astronomical events you can enjoy while in Japan! While many of the below can be seen from Tokyo, when you're out in Japan's countryside, clear skies afford a sparkling view of the heavens like no other - especially on some of the more remote islands. Here is a monthly guide to some of the more beautiful events in the heavens above Japan!

January 2019 Astronomical Events in Japan

January 1 - Conjunction of the Moon, Venus, Jupiter
Gazing up at the sky just before sunrise, you'll notice two bright objects - Venus and Jupiter - in line with the moon, making for a beautiful way to greet the New Year. Look for this impressive sight in the east.

January 4 - Quadrantid Meteor Shower
The Quadrantids are 2019’s first major meteor shower and are expected to peak during the evening of January 3 (around 11pm) and last until around dawn on January 4. Although the meteors will appear to originate in the northeastern portion of the sky, they will be visible throughout.

January 6 - Partial Solar Eclipse
The Sun, Moon, and Earth will align in a way that the moon will partially cover the Sun's disk, resulting in a partial solar eclipse. The eclipse will start at 8:43am in Tokyo, reach maximum at 10:06am, and finish at 11:36am. The more north you are, the greater the amount of the sun will appear eclipsed. Although the eclipse will be viewable from Okinawa, it will be more outstanding in Hokkaido.
*Note that you can only safely view this eclipse with appropriate equipment! Do not attempt to look directly at the sun or you will damage your eyes.

January 6 - Venus at Greatest Western Elongation
January 6 is has a double show in store! Venus will reach its greatest eastern elongation - and will be an excellent time to see our planetary neighbor. Look for bright Venus in the eastern sky before sunrise.

January 21 - Supermoon
The full moon on this evening will look a little larger than usual.

January 21 - Total Lunar Eclipse
A total lunar eclipse will also occur on this date, but will not be visible from most of Japan.

Important note on viewing solar eclipses!

Important note on viewing solar eclipses!

While lunar eclipses (where only the moon - and not the sun - is visible) are viewable with the naked eye, despite their beauty, solar eclipses are dangerous to the naked eye and special viewing equipment is necessary. Never look at the sun directly - even with sunglasses! Instead, ahead of a major solar eclipse you will find eclipse glasses for sale in many variety shops around the country. Safety first!
