In Japan, green tea is the most popular drink among adults aged 20-59 years old. It has been an integral part of Japanese culture since its introduction from China during the Nara Period. Green tea has many health benefits due to its high levels of antioxidants and polyphenols, and it can be prepared using hot water rather than boiling water like other types of teas. Other popular drinks in Japan include beer, sake, shochu, and coffee.
