Great episode overall, but one extremely sticking point that shouldn't have been confusing after seeing the other movies. Han is almost certainly American, and is DEFINITELY not Japanese. There are constant meta jokes throughout 4-6 about how he's never been to Tokyo and has always wanted to go there, which is why (beyond him being alive) everyone knew Tokyo Drift occurred last in the chronology even before it was obvious they were going to unite them all. Even if you hadn't seen 4-6, it should have been apparent that his home was in LA because people that were clearly supposed to be his family were there. The entire segment joking about stealing his body had odd, unintended racial consequences because of this oversight.
