My grandmother loved 水無月. I remembered this only when I started writing about it — the specific way she would describe it, the anticipation she brought to the season. She had memories of it from her own childhood that she passed along in the way that food memories get passed: not as information but as feeling.

水無月, minazuki, is a wagashi eaten on June 30th — the last day of the sixth month, the midpoint of the year. It is a white triangular sweet made from uirō, a firm rice flour base, topped with a layer of sweetened red azuki beans. The white and the deep red together. The triangle, some say, is meant to suggest a piece of ice — cooling, in the heat of June.

夏越の祓 — the mid-year purification

June 30th is 夏越の祓, Nagoshi no Harae — the mid-year purification ritual. At Shinto shrines across Japan, large rings of woven grass called 茅の輪, chinowa, are erected at the entrance to the shrine grounds. Visitors pass through the ring in a figure-eight pattern — left, right, left — as a way of cleansing themselves of the accumulated impurities of the first half of the year.

The idea is practical in its symbolism: you have lived six months, and things accumulate. Mistakes, anxieties, the residue of difficult moments. You pass through the ring and leave them behind. The second half of the year begins clean.

水無月 is eaten as part of this ritual observance — the sweet that accompanies the purification. The red beans are understood to ward off misfortune. The act of eating is a kind of participation in the ceremony even for those who do not visit a shrine.

和菓子 and the calendar

水無月 is one example of something broader: 和菓子, wagashi, Japanese confectionery, is one of the most season-specific food traditions in Japan. Each season and each major ritual moment has its associated sweet — the shape, the color, the ingredients all chosen to reflect where in the year you are. Cherry blossom sweets in spring. 水無月 in June. Moon-shaped dango at tsukimi in autumn. Kagami mochi at New Year.

This attentiveness to season in food is characteristic of Japanese culture more broadly — the idea that what you eat, when you eat it, and how it looks should all be in conversation with the time of year. A wagashi made for June does not belong in October. It belongs here, now, at the midpoint of the year, when the summer heat is settling in and the 茅の輪 stands at the shrine gate.

My grandmother understood this without needing to explain it. The sweet tasted right because the moment was right. That is what she was passing on.
