Today, I read about the Westminister Quarters, the chime used by Big Ben in Westminster, London. In that article, I see this assertion:
Most schools in Japan, Taiwan, and South Korea play the chimes to signal the end and beginning of periods.
My personal experience in Taiwan, in the Chinese communities of Southeast Asia, and seeing videos of Japanese schools suggest that the assertion is plausible. (Also, anime sometimes play the chimes during school scenes).
The Japanese Wikipedia article on chimes has additional information. The article asserts that in Japan, the chimes were adopted in 1954 by a person named 石本邦雄. The adoption was inspired by the chimes played on BBC radio broadcasts. There is no citation.
I find it interesting that the chimes has mass adoption in a select few East Asian countries, and I think it is unlikely to be mere coincidence. Questions:
What was the reason for the mass adoption of the Westminster Quarters in Taiwan, Japan, and South Korea?
When did these places start adopting the chimes?
