It's a stray cat living in Ujina Park beside the Hiroshima Port.  I can speak with cats because I kept a numbers of cats in my home when I lived in Tokyo twenty years ago.  So I made some conversation with the cat and get friend with him (her?).  At first he was surprised with big sound of EOS 1N shutter and jumped backward, but he ignored the sound after several shots I took, and was dozing over.......
