This article from Kumanichi (paywalled) says that from the middle of next year they are planning to stop payments on Kumamoto buses and trams using national transport IC cards such as Suica. The reason is due to the cost of updating the payment machines. Options such as tapping/touching with debit or credit cards will still be possible. I’m wondering if you will still be able to use the Kumamon IC card?? If anyone has access to the full article ask they can share more details that would be great! Michaela
