There are special laws relating to multiple people riding on a single bicycle. Breaking one of these rules can result in a fine of up to 20,000 yen. Normally, only one person should ride a bicycle at a time, but a rider over 16 years of age may carry up to two additional preschoolers (6 years or under) on specialized seats on the bike or somehow securely attached to the driver (if under 4 years).
However, a bicyclist may not carry 3 additional passengers on his or her bicycle, even if they all are preschoolers. Riders should make sure that their bike is labeled with either national safety mark (BAA or SG).
