Why not reduce it to Sesso and just have it "derived" from the Japanese word?

As "Sesso" - I wouldn`t immediately recognize it as being Japanese, and it would be hard to pronounce (sess-oh).

There is really no need for it to be a real word, correct? Just modify it to fit with what looks good to you.

Sesso would strike me as a normal sounding company name, and for some reason even seems kind of tech-related.
