Ohajiki

Ohajiki (おはじき) is a traditional Japanese children's game similar to marbles.

It is played with small coin-shaped pieces also called ohajiki.

Modern pieces are typically made of glass or plastic, but in the past seashells, pebbles, and Go stones were used.

[1] The word ohajiki is the noun form of the verb hajiku, which means "to flick".

[1] Historically, the shell of the kisago sea snail (Umbonium costatum) was used as ohajiki pieces.
