Hello jborsecnik,
There are quite a few restaurant supply stores at the Kyoto Wholesale Food Market near Tambaguchi Station.
See map at the link below. (The photos at the link below are mostly of fish and vegetables, there are other other stores that sell the items you mention above too.) I hope this answers your question.

By the way, the wholesale market is not that much cheaper than a lot of retail stores. Be sure to bargain with the vendors at the wholesale market and get prices from all the relevant before you make a purchase.
Also, if you can read Japanese or have a Japanese friend that can help you search you can often find good deals online.
There is also Gyomu Su-pa- (業務スーパー), a super market chefs and restaurants. I haven’t been to one yet but I know people who shop there. They aren’t very sexy but there are several in south Kyoto.
