The 15th day in the 8th month of the lunar calendar (between mid-September and mid-October of the modern calendar) is called the 15th Night (Juugoya) in Japanese, and is said to have the most beautiful full moon of the year. It is well-known as a great time to enjoy some moon-watching.

Don't forget to enjoy the full moon if you visit Japan in the fall, not just the wonderful autumn scenery!
