Gilldo, I undertand the sentiment of your comment but it's worth noting that this while this is the case for most foreigners, some people can in fact transit - Japanese citizens, residents, and those with certain visas. I'm pointing this out because there's been a bit of an outcry about "why do the airlines show these unusable itineraries" when in fact, airlines have no knowledge of whether their customers have the required visas or not. There are still a large enough group of people that can in fact transit, along with the uncertainty of when transit will be available for the rest of us, that it's reasonable for airlines to make these itineraries available. It's always been the responsibility of the traveller to know if a certain itinerary is suitable for their visa/passport status.
