WHERE THIS CAME FROM
Most first visits to Japan run along the same line: Tokyo, Hakone, Kyoto, the same three temples, the same two shopping streets. It is a decent line, and it is the one printed in every guidebook.
What was missing was the layer underneath: the counter that seats eight, the ryokan with no listing, the morning at a workshop that does not take visitors. None of it is findable from outside, and almost none of it is bookable.
So STAYGO does the part that cannot be done from a laptop abroad: the calls in Japanese, the introductions, the reservations held months out, and the rerouting when a typhoon lands on the day you were going to Hakone.
The rest of the trip is yours.
