I'm not a specialist of this field ,but just an amateur. There is mountain Fuji behind the heron, and clouds float across the sky.
Mt. Fuji is the highest mountain in japan, and it's a volcano.
In edo-period,it burst sometimes, for example in 1627,1700 and 1707. And it is also a holy mountain. I can see beautiful mt. Fuji with snow at my house in winter. My name is Yuji Hirakawa.
