The first one’s a free PDF so you can sample. The first three are like six or seven bucks as bundled PDFs. The later ones are not but he runs sales sometimes.
The readers are super-simple.
There are no questions or tests or quizzes. I’ve used trad textbooks-- the last was New Approach ニューアプローチ中上級日本語 at the Yamasa Institute. Grammar points with short texts on some topic, then audio and questions you answer. It’s good if you want that. I found it really hard to revisit once class was done. I think long grammar explanations like that stick best when you already kind of know the grammar point from seeing it in the wild, but you’re not entirely sure.
In the KLC readers, each kanji entry has several passages in Japanese; then the reading; then an English translation. After that, any new grammar is cross-referenced for Genki, Marx(?), Tobira, and the three-volume Dictionary of Japanese Grammar. Some entries are only DJG. I guess the others don’t cover those grammar points.
They’re focused on using texts to teach kanji readings. Grammar’s incidental, but there’s a lot of it. Without other grammar instruction I don’t know that KLC is your best option for that.
Here are two sample entries from Vol. 6:
1009-1. 中断された睡眠。
中断(ちゅうだん) された 睡眠(すいみん)。
Broken sleep. (101)
…
1009-32. 着衣は大変乱れていたが、それは彼が眠ってるところから、飛び起きたのだろうと思われた。
着衣(ちゃくい) は 大変(たいへん) 乱れ(みだれ)て いた が、 それ は 彼(かれ) が 眠っ(ね
むっ)てる ところ から、 飛び起き(とびおき)た の だろう と 思わ(おもわ)れた。
His disordered dress showed that he had been hastily aroused from sleep. (1)
「〜ようにおもわれる / 〜とおもわれる」 {〜ように思われる / と思われる 142} [“seem(s) __”]:
DJG v2 p325; Tobira ch4 #2.
I picked the first and last ones for Kanji 1009. Most are short like #1, with the last 8 or 10 longer like #32. The texts are all public domain sources listed at the back.
There’s like 30,000 text samples in the series for 2300 kanji entries. You will see readings and grammar over and over and over, learning them organically. I level up to 50 tonight then will finish Wanikani lessons in five or six weeks. I’ll probably guru everything and then output a list of what I know and don’t know for reference, and then probably never look at it again. WK really has helped, but I moved most of my study time over to these readers about a month ago when I found them.
It’s like an SRS that never repeats itself. And it has no leeches since you never get anything wrong.
