If you like incense, on Awaji you can visit Kunjudo.
From Sannomiya Station you can catch a JR train to the bridge and then a bus to the island, but it's easier and probably as quick to take the bus all the way from out the back of Sannomiya station.
The shop only takes cash.
This turtle I met at the bus stop is probably a native species, but I do not know anything else about it.
I was inspired to buy these pottery turtles in Okayama a few days later.
