In the vast ocean of isekai manga, most stories follow a familiar blueprint: a teenage boy gets hit by a truck and wakes up in a fantasy world with a harem, a cheat skill, and a vague goal to defeat a demon lord. However, Nihonkoku Shoukan (日本国召喚, literally "Summoning Japan") flips the script entirely.
In this new world, Japan discovers the "New World," a planet dominated by the Rodanius Kingdom , a medieval society with swords, magic, and wyverns. Nearby, the militaristic Lourian Empire sees Japan as a soft target. They send a massive fleet of wooden sailing ships and a squadron of wyvern knights to invade what they call "the land of the gods."
This article explores everything you need to know about the Nihonkoku Shoukan manga, where to find the raws, why the series has garnered a cult following, and what makes it different from standard isekai fare. Before diving into the "raw" aspect, let’s establish the premise. Nihonkoku Shoukan began as a web novel on the Japanese site Shousetsuka ni Narou (Let’s Become a Novelist), written by author Minorou . It was later picked up for a light novel publication by Hobby Japan and subsequently received a manga adaptation illustrated by Takumi Kayanagi (also known as Chankomodoki ).
