And how it’s done in Japan if friends don’t help?

Same way works in eastern Europe. And especially if you give away furniture to get new one,you can ask person who gets your old stuff to help you to bring a new stuff. As a female, this always worked for me.
Only once I paid something like 50 eur for sofa delivery, because it was during week that I had to pick up from private on certain time and friends were working.
