Facing rapid changes due to the influence of COVID-19, the environment has changed in various forms that have never been before. In particular, the development of ICT has created a new world in virtual spaces such as Metaverse, and new contactless services, including LAN-based cultural activities and concerts, have spread. In addition, domestic travel has increased rapidly for those who have difficulty traveling abroad, and accordingly, a new type of travel has been defined and participated.

In particular, the frequency of domestic travel is on a steep rise, especially in several countries that have begun introducing the With Corona policy. For example, if look at air passenger data based on the TSA's checkpoint under the U.S. Department of Homeland Security, air passenger traffic has been steadily increasing since January 2021, and traffic has recovered quite a lot in 2019.
