Both Japanese men and women drink more alcohol than their American counterparts. Average consumption of pure alcohol in liters per year among all adults aged 15+ in 2019:
Japan Men 15.58, Women 4.93
United States Men 15.44, Women 4.69

This article might be alluding to an age difference since I am in my early twenties, but I can attest that I am a weak drinker but I drink more alcohol than virtually every Japanese person I have known - only Westerners and a number of Asians such as Koreans can drink in the same pattern as me. If you are an older person then it is common everywhere for married men to drown their sorrows in bars and pubs etc...
