[Touji] The Winter Solstice or Midwinter occurs around December 22nd each year.
It is marked by the shortest day and longest night of the year. In ancient times, people often had difficulty finding enough food in winter because most plants died and many animals hibernated. In addition, with shorter days, people could not fully enjoy the blessings of the Sun, causing them to worry about their well-being. As a result, they began to perform rituals to encourage prosperity, which is the origin of the modern Midwinter traditions. At this time, many in Japan take yuzu bath in an effort to stay healthy during the cold winter.
