Part-time Saturday position in Kumamoto

Hello kind folks of Reddit,
I run Sam's English, a small language school in Kumamoto, and we are looking for a native-level English speaking teacher for our Saturday program. We have around 20 students ranging in age from 4 to 12 and on a typical day mix traditional study in small groups with experiential learning, English play, science, art, cooking- whatever your interests are, bring them along!
We are looking for someone who has experience with lesson planning for beginner English learners who would be comfortable bringing in a 30 minute teaching chunk each week as well as collaborating with other teachers in play time and activities. Along with our regular roster of 3 teachers, we have a Japanese administrative staff member available at all times for emergencies and additional support.
Hours: 11:00-3:00, four Saturdays/month. Half-days are a possibility.
Pay: Starting at 11000/ Saturday.
Benefits: No formal benefits, but we offer profit sharing for bringing in new students.

I know working Saturdays is a tall order for most, but if you're interested or have any questions, send me a message! If you'd like to check out our school, if you search Sam's Kumamoto or サムズ 熊本 our school should pop up.
Thanks to the mods for letting me post!
