Long shot, i didn't find anything on viator/getyourguide/klook etc. I found this https://omakase-tour.com/tours/Destinations/Nagasaki/nagasakis-historical-temple-street-walking-tour.html but can't find a way to book it.
It's such an incredible historic city, i'd love to get some local insight! Appreciate it.
