It has long been a common saying in Japan that ‘no heat or cold lasts over the equinox (Higan)’: the heat of summer calms by the autumnal equinox, and it is getting cool these days.
We hear the chirping of insects and enjoy the moonlight (Tsuki-mi) at this time of the year. ‘Higan’ is a traditional week-long seasonal event each spring and autumn. It has seven days, centering on the spring equinox (Shunbun-no-hi) in March and autumn equinox (Shûbun-no-hi) in September.
Red lovely flowers called ‘Higan-bana’(literally ‘equinox flower’: cluster-amaryllis) start blooming all at once as if they were expecting Higan. It would be a lot of fun to try to find ‘Higan-bana.’
