Leadership changes within Japan's political landscape are underway with Mr. Tamaki demanding the rectification of income disparity among executives. He, as the newly appointed chairman, asserts that inequities in annual incomes should be addressed swiftly. His aim is not just to stir a debate, but to pursue and actualize this policy reform.

Income disparity in Japan, particularly among executives at various levels, is a pressing matter that directly influences the standard of living and social fabric. Japanese public and politicians are increasingly concerned about this issue. Mr. Tamaki's proposition aligns with this growing sentiment, highlighting the urgency of tackling economic imbalances.

In the US or the EU, income disparity has been a long-discussed topic. Many governments are seriously considering the implementation of salary caps, minimum wages, and even universal basic income to address the social and economic impacts of wealth inequality. Tamaki's demands resonate with these international calls for change.
