Goka Yajin, a manga artist instantly recognizable by his jinbei robe and headband, travels the world with no fixed itinerary, letting chance encounters guide his every step. This work is an expanded, book-length version of his popular social media series Tired? Read This Overseas Travel Diary, delving far deeper into the spontaneous human connections that a guidebook never captures. Each journey begins with a simple approach: meeting a local, accepting an invitation to their home, sharing a meal, going for a drive, and listening to life perspectives that differ from those in Japan.

The narrative unfolds as a series of real-life destinations rather than a fictional plot. In the first volume, Goka travels to Argentina and Tanzania. In Argentina, he befriends a local named Henry, whose casual wisdom about treating people well leaves a lasting impression, and he shares a poignant, fleeting bond with a stray dog. In Tanzania, a young man he meets leads him to a film audition and a live radio appearance. The second volume returns to Tanzania and adds Laos, deepening the home-visit format as Goka steps into the daily lives of families and strangers. The third and fourth volumes take him to Papua New Guinea, where he crosses the equator for New Year's, samples giant frogs for collagen, joins a minority tribe's drinking party, and crashes a deeply local wedding. The fifth and final volume arrives in Morocco, the "world's greatest maze city," where ancient streets and the people living in them today create unforgettable encounters. The series closes with a special bonus section, Overseas Masters and Their Exclusive Stories, in which Goka visits restaurants in Japan run by immigrants from the countries he explored, tracing the threads of connection full circle.
