A travel blogger documents the fourth day of a campervan journey through Aomori Prefecture, visiting Mount Osore and Tanohata Coast. Mount Osore, one of Japan's three sacred mountains, impressed the author with its volcanic landscape of sulfur vents and barren rock, contrasting with the emerald-green Lake Usori, which is described as a 'paradise' after the 'hell' area. Tanohata Coast is noted for its natural grass extending to the water's edge. The author also collected Pokéfuta (Pokémon manhole covers) in Iwate Prefecture, noting their large number makes complete collection impractical. The night was spent at a roadside station in Noda.
