Traveling With One Smartphone

Traveling With One Smartphone – video still: an airport security tray containing only a smartphone and a passport

Traveling With One Smartphone
2017–ongoing
Performance, video, installation

This is a performance art piece that Yamaguchi has been practicing since 2017, involving domestic and international travel with only a smartphone (and a passport for overseas trips). The work challenges the concept of “national borders,” which often present a significant psychological barrier for Japanese people raised on an island nation, by crossing them with the same ease as visiting a local cafe.

In this minimalist journey, where basic travel essentials such as clothing, cash, and chargers are completely abandoned, modern technology and the kindness of strangers become indispensable. Yamaguchi intentionally places himself in this “vulnerable” state, surrendering to unpredictable situations and responding to them spontaneously.
