いろはうた(Iroha-uta) are poems composed about 1,000 years ago by an unknown author without duplicating the 47 kana characters of the Japanese language.
Since ancient times, paper cranes have been made by folding squares of paper to express wishes for peace and happiness.
The outside of the teacup depicts the development of the folded paper crane, and the inside depicts the completed folded paper crane.
In these times, we cannot help but pray for peace and happiness with origami cranes.
Ten words are used to express the wishes that are contained in matcha.
