The best course of action is, of course, to transport the sword in a closed container in the trunk or, if the vehicle does not have a trunk, in an area of the vehicle that is inaccessable to the driver or passengers.
MCL750.227. (1) A person shall not carry a dagger, dirk,
stiletto, a double-edged nonfolding stabbing instrument of
any length, or any dangerous weapon, except a hunting
knife adapted and carried as such, concealed on or about
his or her person, or whether concealed or otherwise in
any vehicle... except in his or her dwelling house [or]
place of business... (3) A person who violates this
section is guilty of a felony...
Technically, unless the sword is double edged, the sword appears to be legal within the vehicle, but I WOULD NOT CHANCE IT!!! (I am not a lawyer). The police may/could/probably will attempt to define the sword as any of the items listed here:
or as listed here, if they think it may be used illegally. You may think, he wouldn't use it illegally but, there are many laws regarding "martial arts" and there may be license requirements for such activities state law.
MCL 750.226... Carrying with unlawful intent

be guilty of a felony, punishable by imprisonment in

of not more than 2,500 dollars.
