Seems a bit "twee" or whatever the word is, is it embossed into the paper or just very faint lines? And why show only Japanese handwriting when you are putatively, willing to sell it to people who will write in English?
Japanese book printing and binding have long been top-level, too. I used to help edit dictionaries for Japanese publishers, and I ended up collecting several hundred paper dictionaries from around the world. The Japanese dictionaries had the clearest printing, the thinnest and most opaque paper, and the strongest and most flexible bindings.
