There’s a group called “Kumamoto YWCA International Neighbors” that plans occasional events to help people learn Japanese, etc. The event described on the page I’m linking to is already over but I’m sure there will be similar events in the future. If you’re interested, please use the contact information included in the message to inquire. – Kirk
