I found this book cover over at the Zabou shop blog, and while I don’t have a clue of what it might say I have a sneaking suspicion that it’s some sort of Japanese mountain style-bible. Either that or it’s actually a guide to the outdoors for the Japanese… regardless, I still think it’s an amazing likeness of myself in the winter months when I gravitate towards buffalo plaids and fall behind in visiting my barber. Any tips of what lies inside of this book would be greatly appreciated.

I believe the title translates to “The Book of Heavy Duty”.
Hmph, thanks for the tip!
