Apologies in advance, this is a long one but hopefully you might find something suitable
I’m on Learn Natively and I have also read the book you’re currently reading. I would recommend children’s books around natively level 18-20 for things of a similar grammar level but be aware that you may need to do many look ups for Vocabulary that you don’t know and may also struggle with longer sentences. Novels/ Children’s books and Light novels around Lv23 will be a lot more difficult than the Olly Richards book.
A lot of the books I’ve read on their site around that level are much harder, mostly because there are no vocab lists and they are actually written for native speakers not learners so the grammar is different. Olly richards stories are not written for native Japanese speakers so they do aline more with how a learner would understand (easier grammar used) but feel off to someone who is a native speaker (I had my tutor and some of my language exchanges read parts of the stories and they all said it was understandable but didn’t feel quite how it should).
The Kitty detectives/ Doggy detectives are native but a lower level (なャンなャン探偵団 / わんわん探偵団). Around the same level as the ミラーさん novels from Minna no Nihongo, though I found the Kitty detective series more difficult because it’s written for natives and contains more vocabulary than I knew.
世界の真ん中の木 I felt was a bit easier than other Lv 23-24 books, it has some pictures though but very little furigana.
There’s also Olly’s 30 day mastery series which is similar in difficulty to his short story book but shorter chapters and each book is only one story but helps you to better understand basic uses of certain words and grammar points.
Something that shows around the same level as the Olly Richards short stories would be things like this. Although around the same level on the site, they are much more difficult due to lack of vocab list and lack of summary. The sentences are longer and more complex than what Olly Richards uses. Not to say it’s a bad thing, just to say be prepared for a more intensive experience.
Other graded readers I would recommend are:
- Intermediate Japanese short stories (there are 2 beginner level ones both those have full translations whereas this one has just a vocab list, questions and summary like Olly Richards iirc, also has audio available separately).
- Let’s read Japanese each book has a few stories that get longer and more complex as you go up the levels (content warning for the last book which has a harrowing account of a historical event) beginner ones are about on Par with the Olly Richards book iirc. Also liked the fact it has some folktales and traditional non fiction stuff thrown in for cultural aspects.
- Short stories for language learners 2 books that have a mix of folktales and short stories with access to free audio online. These have the full story in Japanese and an English translation separately. And are around the same level as the Olly Richards ones.
- the Read Real Japanese series you mentioned is great too. Breaking into Japanese literature is another but be aware of trigger content rape, cannibalism, murder, mutilation
Any book is accessible, but it’s more about how much time and effort you want to put in, to making it comprehensible as well as how much ambiguity you can tolerate and how many look ups is too much.
I read Zoo (a Japanese short story horror book by 乙一) after spending a lot of time with graded readers and of the 6 short stories, I understood the majority of 2 of them but missed a major plot point, understood parts of 2 so I got snippets of what was happening but didn’t fully understand, and then completely blanked on the other 2. I also had similar experiences reading things around the Lv 22-24 mark but it is a good jumping off point on e you get comfortable with the grammar and a lot of the common vocal for the genre/s you choose.
If you find an author you like or a series you like, stick with it and it will help your progress ![:slightly_smiling_face: :slightly_smiling_face:](https://emoji.discourse-cdn.com/apple/slightly_smiling_face.png?v=12)
