In Japan, the housewife generally takes care of the money, budgeting and bills. The husband gives his paycheck to the wife. She gives him an allowance and then she makes sure all the bills get paid, etc. In the USA couples usually do what works for them. There isn’t necessarily a standard way to do it.
When you are in a restaurant, it is generally the wife who pays the bill. I always chuckle when I see my hubby waiting in a line of women waiting to pay our bill. My husband always chuckles when they lay the bill in front of me. 😉
