This seems like a very hand-wavy comparison. By the numbers, the difference is enormous--Japan's average household net-adjusted disposable income per capita is $28,900. For direct comparison, the USA's average is 77% higher than Japan's at $51,100. Japan's average is even below the OECD average (which includes a mix of leading Western countries and less developed countries like Costa Rica and and Hungary) by 5%.
