I am uncertain as to who the men in the center are. If I had to take a guess the man in the middle might be Prime Minister Prince Higashikuni but that would be a complete guess. The only person that I might be able to identify is on the far left, who appears to be John Foster Dulles. If this is in Japan this would suggest this took place around 1951. Hopefully someone else can help here, I do not believe the two would have met.
