If you want "official" translations, I'd recommend YenPress. Look them up, they have quite a lot of series translated, including series like Spice and Wolf and Tanya the Evil.
There is also BookWalker, they have apps for pc and phones/tablets, so you can purchase ebooks. They have all official translations and a lot of discounts and special offers.
Tell me again how long will it take for them to translate one volume? Years have passed, my fellow reader. We are now ancients buried deep under the sands of time.
He didn't ask how long, he just asked for "official" translations lol. This is also why I usually let their series sit for about 2-3 years before considering getting them.
Most of them are already been completed in japan. The problem lies on the company translating and releasing "official" translations and hard copies.
They are mainly managed by Japanese people, right? I assume there are fluent English speakers or writers in the company; or some native English person helping or directing the business. Then again, with having remembered issues with pronunciations or spellings, improper printing, or etc., I rather not have that much faith. I'll stick with fan translations with patience than wait for "official" translations.
J-novel club. Though, I don't think they do hard copies. Amazon usually filters for official translations, so if you want to find a translated LN, you can try searching for it there. There's also Yenpress, but as people already pointed out, they release very slowly, but they do have a lot of the highly rated novels, novels such as: Goblin Slayer, Kimi no nawa, ReZero, etc. I also remember that they sometimes have sloppy translations. Oh, and one more thing: Yen Press has very loose copyright/DMCA laws.
A lot of those are NOT webnovels. Webnovels toss out a chapter a day with varying quality. "Real" authors publish a book every year or bi-annually. The timescale is massively different. Look how long it took for Weber to finish his Harrington series or an even more extreme example Robert Jordan never finished his Wheel of Time series before he croaked. Merville's Moby Dick took 4 years to write. This is the "correct" timeframe for normal authors, we're just too used to the production line crap produced daily by the internet that we forget this.
You got wrong novels there. Light novels are called light novels because they are shorter than the classic ones you listed. Light novels have max 10 chapters with epilogue and extras. I finish reading one volume in a couple of hours, regular novels take days. The authors release around 2-4 volumes a year, depending on the story’s popularity. They generally start publishing as web novels, gain popularity, get proposed by publishers and you have it, light novel. The published light novel can have plot alterations from the web novel, the authors get feedback from the company to polish the plot. I don’t know how long it takes to translate the volume because they don’t translate it immediately and see how popular the novel is in Japan first, so yeah, they “sit” for a few years. But if they decide to do long popular series, they will release it quite often, maybe every two months max, depends on its popularity here. More obscure titles take a long time, that’s for sure.
