A KK in Japan is currently the least expensive option. Basically all you need is to pay for the registration paperwork (about ¥300k) and what used to be a minimum capital of ¥10 million has now no minimum.

There used to be Yugen (limited responsibility) with a minimum capital of ¥3 million but it disappeared with the new KK law.

That was about 12 years ago.

Depending on your VISA type you can also operate as a sole proprietor (kojin jigyo) as I understand it. I think that’s cheaper and easier?

I’d still just be tempted to set something up in another country and operate via that until things started to pan out.
