Where can I find…a bunch of unrelated things in Kansai

Hi all,

Moved to Kobe a couple months ago. Still looking for the following (things that have been rather difficult to do our own searches for) (anywhere from Akashi all the way through Osaka is fair game):

Good places to buy large shoes (both my partner and child wear men’s US sizes around 12-13!)

Good lumberyards and tool shops where actual carpenters and contractors go (we’ve been able to find an okay amount of stuff at places like Kohnan and Agro, but those are still pretty limited)

Good agriculture/garden supply stores (again, ones more “hardcore” than Kohnan and Agro, which are good places to start, but)

How to get flu vaccines

Thanks!
