Fellow BMV holders – cheaper private office choices than Regus?

Regus was easy to set up from overseas, but now that I'm here and the contract is expiring, I'm looking for a change. I rarely go there anyway. WeWork private offerings are too expensive.

I think HUB (thehub.nex.works) has some better choices, but I'm curious about even better choices. I'd love to make the 1F of a 3F home an office, but maybe that's next year depending on the Business Manager Visa changes…

edit – currently in a mansion, so I can't execute that "home office on 1F" plan yet.

What about non-traditional office space like a small storefront/retail shop? How would I go about finding those in the Yokohama/Kawasaki area? Just enlist an agent?

thanks!
