If someone finds a lost item in Japan, there is a good chance it will be returned to the owner. The law requires finders of lost items to receive 5-20% of the value if claimed, or to keep the item if unclaimed after 6 months and 14 days. Studies show wallets left on the street in Japan are more likely to be returned with cash intact compared to other countries like the US. This is partly due to cultural norms of honesty in Japan as well as laws requiring lost items be given to police.
