As kimonodo not have pockets, everyday objects are transported in little boxes called sagemono. The netsuke hold firmly inrō’s string, or other types of sagemono, slipped into the obi, the belt which closes the kimono. The production of netsukeflourishes during the Edo period.

The soroban originates from the Chinese abacus (suanpan). Unlike the suanpan, soroban only have 4 unary beads instead of 5, and one quinary bead instead of 2.
