We hope that the foreign tourists can resume visiting Japan from this year. If so, planning should be started soon. First thing which you have to do is to book the air ticket.
Many international flights to Japan have interrupted since spring 2020 but we hope those flights will resume too. Then, which airline to take? KLM is one of the few airlines which did not suspend its flight to Japan. Then, they are the one of the European airlines flying to KIX, Kansai airport, the gateway to Kyoto.
