What do Japanese people eat on boys day?

On Boys' Day, celebrated on May 5th as part of Children's Day in Japan, families traditionally eat kashiwa mochi, which are rice cakes filled with sweet red bean paste and wrapped in oak leaves. This symbolizes strength and resilience, reflecting the hopes for boys to grow up healthy and strong. Families may also display carp streamers (koinobori) and samurai doll decorations, emphasizing the celebration of boyhood.
