A tomoe or tomoye (archaic) (巴) is a Japanese abstract shape (i.e. a swirl) that resembles a comma or the usual form of magatama. It is a common design element in Japanese family emblems (家紋 kamon?) andcorporate logos, particularly in triplicate whorls known as mitsu tomoe. One mitsu tomoe variant, the Hidari Gomon, is the traditional symbol of Okinawa.
On the opposite side of Eurasia, the Basque lauburu and some forms of the Celtic spiral triskele resemble small groups of tomoe.
