How much Japanese culture has changed since the 1990's

"I would like to know more about how Japanese culture has changed from the early Heisei period to today, including the influence of globalization and Western culture, and its collateral effects in Japan since the 1990s. I am interested in understanding the differences in mentality between the older generation who lived during those times and the modern young generation. Additionally, I would like to explore the declining emphasis on 'family' values and the adoption of Western individualism in Japan, as well as the growing influence of ESG politics."
