I started researching this topic thinking that it would be simple, but it turns out I underestimated the complexity. I wanted high fantasy novels written by Japanese authors that have been translated into English but found more nuanced choices. I didn’t really want to go into isekai or portal fantasy, but it's going to cross over. High fantasy is like Tolkien’s Lord of the Rings and not set on our Earth. Isekai is about being reborn or occupying a body (kind of sucks to be the previous owner of said body) in another fantasy world, and portal fantasy is just being transported or gated to another world. Some works which are very high fantasy-ish are often portal or isekai, too.By no means is the following list comprehensive, but it contains what I would consider to be some of the more historically significant or interesting titles. There are many fantasy light novels and I have not covered many of them, especially if they are heavy on the isekai theme (and I quite like a few of these, too). Examples that are heavy on the isekai are Overlord, Grimgar of Fantasy and Ash, Mushoku Tensei: Jobless Reincarnation, That Time I Got Reincarnated as a Slime, or Re:Zero − Starting Life in Another World, etc. Some of these books are part of a series, especially if they are light novels. I've also excluded light novels that came after an anime/manga such as Fairy Tail. In addition, works like Spice and Wolf are excluded as they are low fantasy. The following list of books is presented chronologically by approximate Japanese publication date.
