I have been studying Japanese casually for a while and started studying a bit harder last year. My reading skill is probably around JLPT 4 now; I can read about half of the Japanese stories at the end of the issues without looking at the translations, only sometimes do I need to check to understand a kanji or grammatical construction.
I specifically like this bundle, because the subjects appeal to me. I am a fan of Japanese woodblock prints (I am actually wearing a T-shirt with the Great Wave as I'm typing this), I like traveling by train and wish we had shinkansen where I live and I find yokai such as kappa and tengu fascinating creatures.
Now it's the combination of these three things that make this such a great bundle for me.
1) This is good study material that helps me improve my Japanese,
2) the subjects align with my personal interests and
3) as an added bonus I also learn more about Japanese culture.
If you are anything like me and also like to both study the Japanese language and read about these topics, I'm sure you'll love this bundle!
