The US is a wealthier country and wages are higher here than Japan.

The median equivalised household disposable income of a US household is over twice that of a household in Japan.

This is one of many reasons why it’s so misleading to compare prices across countries in a vacuum. All of the people doing the work for those education, transportation, and other services and all of their inputs aren’t going to work for Japan-equivalent pay when they’re living in the United States.
