MT Motorbike licence

I converted my licence to a japanese one, but I have the limitation of AT on motorbikes and I was wondering if there is a way to upgrade directly to MT for 400c or less. I saw there are AT lifting services but they are only for car driving licence (if I understood correctly), but was wondering if it's possible to do the same for motorbikes or I have to do the licence from scratch.

Plus, is there a driving center near Umeda or around toyonaka that teaches in English?
