I doubt there would be much loss of sleep over this by many former POWs of Jap style hospitality
When I was growing up in St.Albans in the 50's, a friend of my father ran a radio & tv shop near us. He had been a victim of just such hospitality & made a point of refusing to sell or repair anything made in Japan. If following this course nowadays , I doubt your business would last long, but to me this has always symbolised the depth of feeling amonst far-east war veterans.
