What is the environmental commuter pass system for municipal buses?

If you have a commuter pass (including a common commuter pass issued by another company) and a senior pass, if you use a municipal bus on Saturdays, Sundays, holidays and specific days, up to 5 accompanying people will be discounted fares. It is a system that allows you to use the bus.

Saturdays, Sundays, national holidays, New Year's holidays (12/25-1/7), Old Bon (8/12-8/16)

Adult 100 yen, child 50 yen (payment is cash only)

※If the boarding section is a commuter pass designated in advance, the person who has a commuter pass can also ride for 100 yen when using outside the boarding section.
※Commuter passes are not subject to this system.
※Please note that the contents of the environmental commuter pass system differ for each business operator.
