One big reason for Japan’s good health is their traditional food. Meals often include fish, rice, vegetables, and fermented foods like miso soup and natto. These foods are full of nutrients and low in bad fats.

People also eat smaller portions and often have many small dishes instead of one big plate. There’s also a saying in Japan: "hara hachi bu", which means “eat until you are 80% full.” This helps people avoid eating too much.

In Japan, people walk and bike a lot. Many use public trains and buses, so they walk to stations every day. Even in the countryside, people stay active by gardening or doing chores.

Elderly people also like to do group exercises. One common routine is "rajio taisō", which are short exercises played on the radio that many do in parks or at home.
