Japan’s largest lake
Video link: http://youtu.be/WKvSP9zmnb8
If you like lakes (especially very old ones), fish, plankton, endemic species, or fermented fish, this video is for you. It’s quite long at 1 hr. 6 min., but you can pause/resume at anytime. Or just watch the first 5 min. and then decide whether to watch it to till the end. Within 5 min., you’ll know if you want to continue watching it or not. It’s pretty educational.
