Great find, glad the recovery went well.
Those vids have some special meaning for me, as a long time ago, in another lifetime, I lived not far from Lake Towada. From time to time I headed up there to visit the small school on the shore, combined primary and junior-high with, as I recall, eight students and ten staff. One day, the principal found a beautiful green snake in a tree outside his office - all classwork came to a halt as all the kids came out to have a look.
Special place, Lake Towada.
