About the Iemoto's Costume

The special costume the Iemoto will wear at the Celebration is made using “Nihon-Akane” (Japanese madder), a rare dye plant.
With the Iemoto’s vision to incorporate “plant growth”—one of the themes of the 100th anniversary—we have been cultivating Nihon-akane for two years, starting in 2024. The costume dyed with this Japanese madder will be unveiled at the Celebration.
