Millet can only be grown in high mountain areas at altitudes of over 1,000 meters, and was a main food for people in the mountains in the early days.
During the Japanese era, it was not easy to get food in the mountainous areas, so they made mochi from local materials for loggers to carry to the mountains as a snack.
In modern times, there are different ways to make millet, and various styles and flavors have emerged.
