International Pressure Washers here?

I wonder if any people outside the US come here?
I’ve seen some british pressure washing youtube channels. Very satisfying stuff given their climate. Lots of lichen.

I’m especially interested in any Japanese pressure washers. I’ve been to Japan and it’s an amazingly clean place, however it’s prime real estate for pressure washing. Idk if it even exists there because there are so few results for pressure washers in the country and I never saw anything that looked like it ever was cleaned. So many areas would benefit from it for such a cleanliness concious people. Streets, subways, stores. They sweep up leaves every morning with brooms and I saw one trying to clean a concrete stain with soap, water and a sponge for 30 minutes and I was thinking I could remove it in 1 second. Probably a noise/pollution thing but if I could sufficiently sound proof a rig or go electric I’d definitely try to break into that market.

There have been several washers from all over the world post here. We have had a lot of aussies, kiwis, europeans (just to lump them all together but they hail from all over and different climates), a guy from spain, cyprus, can’t remember where in africa, and a whole lot of good folk from north of the border. I don’t recall one from Japan, but that doesn’t mean someone hasn’t posted from there. Other countries have different construction methods, so when those guys post it is pretty neat to hear what they do there. One guy saying all roof washes are done with surface cleaners because they are made from concrete and he never saw asphalt shingles.
