It's one of the methods to broadcast that Japan is looking to prosecute Ghosn. The red notice doesn't restrict travel, it aids in awareness. It's an important distinction. There are lots of ways to restrict travel that don't involve public red notices. The red notice can help build a case for detention by a third party, but again, it wouldn't have to be public to do that. Finally, a third party country has to make a lot of practical political and legal decisions around a red notice hit. 1 - do you/can you legally detain, and on what grounds? 2 - do you notify the originating country? 3 - do you start extradition to Japan/Japanese authority, or do you deny entry, or do you deport? Red notices are not uniformly enforced. Assuming a country actually supports action on red notices at all, each country will make it's own decision based on each individual case. See the historical US treatment of Russian origin red notices.
