One popular 'isekai de tochi light novel' series could be 'Overlord'. In this series, the protagonist is transported to a different world and has to deal with various challenges while also having unique powers related to the land or territory in that world. Another could be 'Re:Zero − Starting Life in Another World' which also has elements of the protagonist making use of the new world's resources and territory in his journey of survival and growth.
Well, one of the things that make 'isekai de tochi light novel' stand out is the territorial aspect. In many isekai stories, the new world is just a backdrop. But in these novels, the land itself becomes a character of sorts. The protagonist has to understand the geography, the resources, and the people associated with the land. They might have to deal with things like land disputes, farming on the new land, or even creating a new society on the territory they acquire. It gives a whole new dimension to the isekai genre.
I'm not sure specifically as I haven't read this novel. But generally, 'isekai' often involves a character being transported to another world. Maybe in this novel, the story is about buying land in that other world and building a farm (since 'noujou' can mean farm).
The title 'isekai de tochi wo katte noujou wo tsukurou novel' gives the impression that it could be a story centered around the concept of purchasing land within an isekai setting, which is often a fictional world different from our own. And then the act of creating a farm on that land. Maybe the protagonist is transported to this new world and decides to start a new life by getting land and building a self - sufficient farm. This could involve various adventures in dealing with the new environment, different species, and perhaps magic or unique technologies in that world.
One popular title could be 'In Another World's Labyrinth, My Harem Awaits'.
There's no information available to me about the main characters in this 'isekai de tochi wo katte noujou wo tsukurou novel'. It could be a young person who is dissatisfied with their life in the real world and gets transported to the isekai world. Or it could be someone who has a special skill related to farming or land management and uses it to build their new life in the new world. But this is just speculation without having read the book.
It's difficult to say whether 'isekai meikyuu de harem wo light novel' is popular. While the isekai genre as a whole has a large following, not all titles within it gain widespread popularity. The concept of a harem and a maze in an isekai world might appeal to some fans of the genre, but it also depends on how well the story is written, the character development, and the marketing of the novel.
It's difficult to determine its popularity. Some light novels in the isekai and harem genres become very popular due to their unique storylines, characters, or marketing. However, without any specific data on sales, reviews, or fan communities, we can't really say if 'isekai meikyuu de harem o light novel' is popular.
