Arafou Otoko no Isekai Tsuuhan Seikatsu

Kenichi, a single man in his forties, finds his ordinary life upended when he is suddenly transported to another world while foraging in the mountains. Facing immediate danger in an unfamiliar landscape, he discovers he has been granted a unique ability: an online shopping skill that connects him directly to modern Japan. By utilizing its buy-back function, Kenichi can convert his otherworldly possessions into currency, allowing him to purchase everyday goods from his home country and secure his survival. Recognizing an opportunity, he begins selling these imported items at the local market, where they quickly become highly sought-after commodities that fetch excellent prices. Although he could easily leverage this success to build a thriving business, Kenichi has no interest in commercial ambition. His true desire is a quiet, self-sufficient slow life on the peaceful outskirts of town, far removed from the hustle of commerce. However, achieving tranquility proves far more difficult than anticipated. Just as he settles into his new routine, a steady stream of complications and unexpected troubles threatens to disrupt his carefully planned retirement. Now, Kenichi must rely on his wits and his extraordinary mail-order ability to navigate the chaos. The unconventional story of a middle-aged man seeking peace through interdimensional shopping is about to begin.
