Japan is no longer a primary economic power and their (perpetually falling) purchasing power + incomes represent that.
US GDP per capita is estimated at $92,000 for 2026. Norway is $96,000 for comparison. 340 million people vs one of the world's richest nations at 5 million people. The UK is $60k, and Japan is a mere $36k.
Read that again. US GDP per capita will soon be 3x that of Japan.
Doing a direct comparison of healthcare costs is silly accordingly. At a minimum you need to 2x to account for the drastically higher US incomes vs Japan, and at least 50% higher vs the UK.
The UK and Japan are not the only countries with more efficient healthcare systems than the US. We can look at a variety of countries, some of which have a higher GDP per capita than the US.
If we look at a graph of 'healthcare spending per capita' by 'GDP per capita' [1], we can see that the US is a massive outlier spending ~2x countries with comparable GDP per capita.
In fact, the US has a higher healthcare spending per capita than every other OECD country. By a large margin.

Need to have people go in for checkups and get shamed for unhealthy habits, not really a money question.
