1964 in Japan Wikipedia
Events in the year 1964 in Japan.
1964 is considered a seminal year in modern Japanese history. The Tokyo Olympics and first run of the bullet train reflected a society-wide sense that post-war reconstruction was over and that Japan had rejoined the international family of nations. Diplomatic negotiations underway this year between South Korea and Japan resulted in a formal normalization of relations the following year.
Individuals born beginning around this date were often subsequently identified as "shinjinrui" (or new people) because they had not experienced the suffering older generations had during World War II or the post-war period, and on the contrary, grew up in material plenty.
