A useful Japanese proverb to throw around
Nou aru taka wa tsume o kakusu
“A true hawk hides its talons”
If you’re seeking another option to view the cherry blossoms or fall foliage in the Hiroshima area, there is a nice Buddhist temple easily accessible from the city. Mitaki is a very rich area, complete with Pagoda, waterfalls, Buddha statues, and a nice mountain climb if you’re in the mood. I’ve been told it’s a common field trip for Hiroshima city schools.
From Hiroshima or Yokogawa Station, take the Kabe Line to Mitaki Station. There should be a map at the entrance to the loading platform. You’ll find the path a few minutes walk to the left.
