This is a vertically lined furigana notebook. I thought having it split up into two parts would make it easier to use as a notebook, kind of like how the Japanese newspaper splits up it’s text. I kept the furigana design that I used for the 勉強しなきゃノート.
Here is the amazon.com link, but the book and be found on all amazons under the Aisn or ISBN numbers below:
ASIN : B09BYBFKSK
ISBN-13 : 979-8547539701
Random fact: 縦書きNotebooks do exist in Japan, so if you google ‘縦書きノート‘ you can see some ways they make them! Personally, I don’t like the [boxy design], and I like having space for furigana, but I thought it was cool that they are used just like normal lined notebooks. I was actually inspired to have the notebook show though the character (Ipo, for this book. He was a mutt and was the dog I had before Buuki) from looking at some 縦書きノートs on Amazon.jp
