If you like lakes (especially very old ones), fish, plankton, endemic species, or fermented fish, this video is for you. It’s shows Lake Biwa and the Lake Biwa Museum. 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.
