Ornamental Hairpin (簪, Kanzashi) is a 1941 Japanese comedy-drama film written and directed by Hiroshi Shimizu.

[1][3] A diverse group of people is staying at a remote spa, including grumpy professor Katada, who regularly scolds young husband Hiroyasu for not being strict enough with his wife, an old man with his two grandsons Taro and Jiro, and soldier Nanmura.

When Nanmura steps on a kanzashi, a woman's ornamental hairpin, in an outdoor bath, he has to extend his stay.

[4] Film scholar Alexander Jacoby describes Ornamental Hairpin as one of Shimizu's "richest and most complex achievements"[3] which "boasted outstanding performances from Kinuyo Tanaka and Chishū Ryū".

[6] Ornamental Hairpin was screened at the Berlin International Film Festival's "Forum" section in 2004[7] and at the Cinémathèque française in 2020 and 2021.
