In Japanese, the month is known as sangatsu (Japanese: 三月) or traditionally yayoi (Japanese: 弥生).
The name yayoi has been connected with the increasing growth of plants in spring. One proposed derivation is from iyaohi (弥生), referring to plants growing more and more; another connects it with yayaohi (漸々成長), which means to gradually grow. Other Japanese names include hanamizuki (Japanese: 花見月) and sakurazuki (Japanese: 桜月).
Hinamatsuri, the Japanese festival associated with dolls, was traditionally held on the 3rd day of the 3rd month.
Hamauri[ja] (浜下り) is held around the 3rd day of the 3rd month in Okinawa and the Amami Islands. Its customs include visits to the seashore and gathering shellfish.
