I put overseas tools in the hands of Japanese tradespeople and report back what they actually say — in English.
Japanese trade buyers are conservative. The professional shelf is held by long-established domestic brands, and almost nothing useful about how they're chosen is written in English.
Distributors will tell you a product will sell here. They are selling you the distribution.
So most overseas makers enter Japan on a guess — or never enter at all.
Your tool gets used on real work by Japanese tradespeople and trainees in the relevant discipline. Not a desk review, not a translated spec sheet.
I don't sell your product and I don't take a cut of your sales. That's deliberate — a verdict from someone with a stake in the outcome isn't worth reading.
If the answer is “this won't sell here,” that's what the report says.
I run Bespoke Stay Japan, where I verify Japanese accommodations on the ground and report what I find in English for travellers who can't check for themselves — 57 properties so far.
This is the same method applied to a different subject: something in Japan that outsiders can't inspect, inspected properly, and reported honestly.
I'm building out the tool side now, and I'm taking on early cases at no charge to establish a track record. If that's useful to you, get in touch.
