About This Trend
和菓子の日 (Wagashi Day) is a traditional Japanese day that celebrates Japanese sweets (Wagashi).
The trend is currently popular due to social media posts acknowledging June 16th as 和菓子の日, which originated from an ancient ritual where Emperor Nimmyo offered 16 traditional Japanese sweets to the gods in 848 AD to pray for the eradication of diseases and to invite good health.
