In my opinion, Confucius roots are present in both Korean and Japanese societies but more in Korea since it was popular there and naturally spread out to Japan in the very early days...ironically not as popular in China where it originated from but their decendants are royalty throughout East-Asia. Shared respect and responsibility comes naturally to minimize shame, a negative social credit. Self-shaming rises out of being mindful of one's actions and words. Also helps if you are a Buddhist country. The results are remarkable. For instance you can leave keys in your car, pass out from drinking on the streets with wallet bulging with cash and almost no Korean or Japanese person would think of even touching it. Note that this does not mean theft is absent in these countries but I do note that even criminals seem to be regular citizens, blending in as much as possible unlike street gangs you see in North America that advertises it openly. Confucianism was designed from ground up to bring peace and stability in societies during time of extreme political and military upheaval and Chosun dynasty (Korea's longest ruling political power) embraced it and promoted heavily. It's not without problems tho. Speaking as Korean.
