Seriously. You don't have to worry. If the family / "last" name were different; if the first name was different than the given name(s), you could have a problem. If your middle names are ommitted, there should not be any problem. They will see your passport to identify you, the tickets will match other than the missing middle names.
Japan will be no different in that regard than the USA or Canada.
