Easy to implement LMS

I am not an educator, but an ordinary person living in Japan, and I needed to install an LMS to WordPress.
I chose this LMS because it was smooth to install, it had a lot of add-ins even though it was free, and the price was reasonable. Of course, the support chat was also smooth! (And in Japanese!)
They are very helpful because they are familiar with Japanese WordPress themes.
If you are interested in it, please try to install it.
