As would my late paternal grandfather.As would my father in law,
When the war started (for the UK) he was with the Hong Kong & Shanghai bank in Tientsin (now Tianjin, apparently). the Japs had already reached and gone past Tientsin, thoughtfully leaving units around the expat areas. He was twice invited for interview with the Kempetei (sake and rice crackers were not served) and returned home 'visibly shaken' according to my late father. It could have been worse. I remember reading that the HSBC staff in Hong Kong got the chop (literally) on Stanley Beach. The family was interned but were fortunate to be in the only batch of internees to be repatriated, exchanged in a Red Cross 'box' out at sea, somewhere.
I am reliably informed that he would have nothing Japanese in the house, or in the garage. Apparently done very quietly, no tirades, just nothing Japanese.
E2A: happily living in Asia as I do, I have to say that Asians in general are 'wired' differently.
