A 1964 quote from Shinjiro Okamoto with possible relevance to this image:
Eighteen years after the war, I now spend most of my life not as a painter but as an office worker. I will never forget the sight of a huge golf course that I saw from a certain spot in the distance below. There were many groups of people the size of peas, or rather dozens of groups, enjoying the game, dotted around the place beyond the limits of my field of vision. They were all swinging their clubs incessantly, their needle-like silver handles glinting faintly and noiselessly. If I were to substitute hell for heaven in this irresponsibly shiny landscape, would you laugh at me for literary excess? Or would you laugh at me as a clumsy war child, a sick man who does not fit in with peace? To me, war and peace are always opposites, yet they seem to approach me with the same weight when I look at them through the spectacles of the dotted landscape. Therefore, it is possible to draw a straight line in my mind with a ruler between the two points under the catch phrase "from the airplane clouds to the golf course. I would like to walk along this straight line with my songs, which are creative works of art, however modest they may be.
