How much of a hassle really is getting an apartment without a refrigerator and stove?

I've lived in Japan for a long time, but some of the only good places recently are from CJS where they don't come with a refrigerator and stove.

Since I've never dealt with this, and I have back issues, is there a well-known trusted service that can easily just pay them to bring it and install it? Or is it a big deal like you need to purchase it, then hire a third-party to come get it from the shop etc.

Like overall I guess I'm asking is there a shop that's known for just you buy it and they also install it for you? lol. Thank you
