Kirk here. As their website explains, “The YOKA is an English-language newsletter published by the International Affairs Division with the help of current and former Kumamoto JETs.” But, even if you aren’t a JET or a former JET (as I am not), you can still enjoy the publication. The Winter 2023 (as in January-February of this year, I think) edition just came out. Enjoy it and previous editions here:
