Averages of Japanese people (money)

Hi.
Do you have any Japanese friends or live in Japan? If the answer is yes, you may know how much money they have and how is their lifestyle.
Today, I want to write about income of Japanese.
According to National Tax Agency, average Japanese annual income is 4.43 million yen (roughly 3.4 million $ with current exchange rate) in 2021.
And also, according to Statistics Bureau of Japan, average one month food cost of a household is 79,000 yen (~600$). It means average one time meal cost is 2.3$ because average household size is 2.91.
I hope these numbers help you to imagine actual lifestyle of ordinally Japanese people.
Bye.

*I checked each number carefully, but please keep in mind that I can’t guarantee accuracy of them.
