Tsuyu

Japan has five seasons and June is the rainy season, bringing flash floods, damp laundry, mold, and delicious tender warabi mochi (rolled in crushed peanuts). I don't know why warabi mochi is seasonal, but you can only get it in tsuyu.
Here is a haiku I wrote to honor the rainy season in New Hampshire, too.

Damp bath towels sulk.

The big fan churns, exhausted.

Warm rain slaps green plums.
