Tohoku University's Kano Collection is an unparalleled collection of japanese books from the Edo period. The beautiful and grizzly Kaibou zonshinzu anatomical chart has been making the blogrounds lately but that's only one of the countless treasures the Kano Collection has to offer. Stumbling around near-blindly, like a non-Japanese reader such as myself, with only minimal help from the site, I have come across an amazing variety of beautiful objects, such as this picture book, a scroll with images of animals, city map, map of Japan, battle map, another picture book, the Kaitai shouzu anatomical chart and this picture scroll which has my favorite little scene I've come across in the collection. Whole days could be spent just surfing idly through the Kano Collection.
