Cool photos! My workplace is an old machiya [1] in Kyoto that's more than a hundred years old, so I kinda live like the people in these photos (not really of course - no konbini back then).
Thanks so much for checking out the website! I hear machiya are quickly disappearing in Kyoto (often turned into generic apartments) so it's great to hear your friend is keeping the old city alive.
