In 2017 I had an opportunity preparing teaching materials for Japanese, nihongo lesson.
It was covering general vocabulary for N4 level of JLPT(Japanese Language Proficiency Test),
and materials to understand typical Japanese traditions.
The audience was Filipino who provide a professional housework to wealthy people.
Seems like the business went well.
Housekeeping services have been recognized since then. COVID-19 also pushed its establishment.
Anyway, I have some experience to teach basic Japanese, if you are looking for someone, who walks you through how to master Japanese literature, I might be able to help you.
In my class we will use materials related to what you are most interested in, manga, anime, just a regular conversation and so on.
Not in a text book Japanese but for having a conversation or for chatting. As Japanese in written form is way too hard to learn from scratch, starting with small chat would be easier.
Sounds useful or interesting?
If you have strong motivation, it always goes well.
