A lot of posts focus on the 'coming of age' aspect of this movie, but the very overlooked part is the role it played in helping to alleviate many of the stereotypes a very Asian phobic America was after WWII, Korea and Vietnam.
They make a point of showing Miyagi in a US Army Uniform--and a War Hero-- and makes references to detention camps Miyagi's family was sent to (a horribly dark period in American history)...where Miyagi's wife was being sent (pregnant) and where she and his unborn child (son) ultimately die during childbirth. There are also a few scenes in which ethnic slurs are used by rednecks toward Miyagi.
Taking this into light, and taking the fact that Daniel has no father that we know of in this movie, the name Daniel-san (sounds like Daniel-SON) helps demonstrate a father son bond that is overlooked. Much of the conversation between Daniel and Miyagi is about Miyagi's great father in Okinawa, because Miyagi has acquired all this knowledge and wants to share it. Daniel substitutes for the son Miyagi never had and Miyagi substitutes for the father Daniel doesn't have.
