Amazon is one of the most used apps in Japan, alongside LINE and X. A local +81 number makes a local marketplace account for buying or selling look native rather than foreign.
Students and working holiday: People on study or working holiday visas in Tokyo and Osaka use a Japanese number for part-time job applications and apartment hunting.
Amazon uses the number for two-step verification, seller checks and delivery contact.
