It is a legal connection for all intents and purposes, as only tourists are blocked from entering Japan. Business people, students, citizens, people in relationships, and others are allowed and can take that route with no problem. Unfortunately looking at google flights, there aren't many flights that will take off after 5pm without some crazy routing. But you can contact MH and see if they can get you on one of those crazy routings. Probably the only possible route you have at the moment without booking outside of OW points to get to indonesia.
