I Won 4 Billion in the Lottery But I Went to Another World

Today’s spotlight is on I Won 4 Billion in the Lottery But I Went to Another World, a manga adaptation of a light novel. Even the long, quirky title screams “light novel style,” doesn’t it? The protagonist, Kazura, is an extraordinarily lucky man who wins 4 billion yen in the lottery. After quitting his job, he returns to his family’s empty home, where he stumbles upon a mysterious door leading to another world. Unlike modern-day Japan, this world resembles an ancient civilization still using bronze tools. Armed with his lottery winnings, Japanese goods, and modern knowledge, Kazura sets out to rebuild villages and nations. Unlike the overpowered protagonists of classic isekai manga like That Time I Got Reincarnated as a Slime, Kazura feels more grounded. The premise taps into that fantasy of “What if modern technology existed in the past? You’d be rich, admired, and probably surrounded by love interests.” In that sense, it also carries some of the scientific flavor found in Dr. STONE. For readers tired of invincible isekai heroes, this series offers a refreshing twist. Beyond reconstruction and technological progress, there’s also a romantic subplot that keeps readers guessing: Which woman will Kazura ultimately end up with? That said, the pacing isn’t always smooth. While it’s fascinating to watch Kazura introduce new inventions, progress can feel slow. For example, by Volume 1, he’s only managed to create a waterwheel, and later innovations reach only the level of crossbows and cannons. This makes the story less “flashy” compared to other isekai series that thrive on rapid, exhilarating developments. Overall, the manga may be divisive. Some will find it too slow, while others will enjoy its steady world-building. If you like simulation-style stories or manga about developing villages and societies, this series is definitely worth checking out.
