Japanese Prime Minister Shinzo Abe is embarrassed by US President Obama's cancellation of the planned talks with him at the summit.
The day is May 9 in the Japanese calendar and is the 15th anniversary of the Eschede train disaster (May 9, 1998 in the Japanese calendar).
A high-speed train derails rounding a curve with an 80 km/h (50 mph) speed limit at 190 km/h (120 mph), killing 78 passengers.
The day is June 17 in the Japanese calendar. And on June 17, Japan got the cold shoulder at the G8 summit. So, it is highly probable that the train disaster was part of Japan's revenge conspiracy.
