Tonight's moon has a name. Meet Izayoi, Tachimachi and 15 more traditional Japanese moon names — with a precise moon-age calendar, tide names and full-moon countdown.
Every night, the moon has a name.
In old Japan, people did not just watch the moon wax and wane — they named each night of its journey. The full moon is Mangetsu. The night after, the moon hesitates to rise, so it is called Izayoi, "the hesitant moon". Then come Tachimachi ("stand and wait"), Imachi ("sit and wait"), Nemachi ("lie down and wait") — names that trace how, night by night, the moonrise comes later and people waited longer.
Tsukigoyomi brings this poetic lunar tradition to your pocket, together with a precise moon-age calendar.
