Japanese people traditionally bathe at night to wash away the day's stress and dirt, considering it a ritual for relaxation and purification before bed, but many now also take morning showers or baths, especially in summer, for a fresh start. The main cleaning is typically done before entering the hot tub, which is for soaking, making the evening bath a core part of Japanese culture, though morning washing is also common.
Japanese people like bathing very much. Tokyo Gas Inc. investigated the bathing style of 2600 people (15–75 years) in the Tokyo metropolitan area, and reported that 85.7% of people liked soaking in a hot water bathtub [7]. Approximately 70% of people take a bath daily in the winter.
The Japanese bath is for bathing purposes only, not for cleaning. Before entering the bath, wash with soap outside the bath and rinse all the soap off. Use the bath itself only for soaking and relaxing, much as you would take a hot tub. Families usually take baths in the evening before or after dinner.
Bathing etiquette—the basics
Take a shower before entering the baths. If you are at a hot spring, shampoo, body wash and towels will be provided, but if you are at a public bath, you need to rent or bring your own. Each shower has a stool and bucket. Take a seat, and pour hot water over yourself using the bucket.
A survey has revealed that 57% of people choose to shower in the morning instead of at night... are you a morning or evening shower person? 🚿 David Collins probably true, especially the smoking part, but I was a child so wasn't my choice when I got to bathe.
Frequency of Shower Use in Australia
Research on shower habits also uncovered that Australians prefer showers at 7-8 am and turn the shower on for 15 seconds before it hits the desired temperature. While nearly a quarter of the population showers twice daily, once is enough for most people.
Washing in the evening before going to bed can improve your sleep, a recent study reveals. And it seems the Japanese know this benefit before the rest of the world. But, there are some other reasons why they prefer to take a shower at dinner and not in the morning ...
The "Japan 5-minute rule" refers to extreme punctuality, meaning you should arrive 5-10 minutes before a scheduled time, as being exactly on time is considered late, demonstrating respect and reliability, a concept sometimes called "5-minute prior action" (５分前行動). It highlights Japanese culture's emphasis on preparedness, where trains are so precise that delays over 5 minutes get official notes, making being early a crucial part of business and social etiquette.
Sitting and washing is less likely to splash the soap form and water compare with standing and washing. You need to keep the bathroom clean for the person who take a bath after you. Also sitting directly on the floor is not hygienic. For these reasons, they use a low shower stool in Japanese bathroom.
No, you cannot wear underwear or swimsuits in a traditional Japanese onsen bathing area; full nudity is required to maintain hygiene and respect for the communal bathing culture, with a small towel used for modesty when walking but not submerged in the water, though some modern or unisex onsens might have exceptions, so always check.
The "3 Date Rule" in Japan refers to the cultural tendency to make a formal love confession (kokuhaku) on or around the third date, marking the transition from casual dating to an official couple, often after building trust with lighter activities like meals or walks, and it's considered a crucial step for clarifying relationship status before deeper intimacy, though it's a guideline, not a strict law.
The washlet can replace toilet paper completely, but many users opt to use both wash and paper in combination—although use of paper may be omitted for cleaning of the vulva. Some wipe before washing, some wash before wiping, some wash only, and some wipe only—each according to their preference.
Research by Kantar Worldpanel confirms that Brazilians take more showers than people in any other country, averaging at least two showers per day or 14 showers per week. This frequency significantly exceeds the global average of five showers per week.
The leading cause of death in Japan is consistently cancer (malignant neoplasms), accounting for about 30% of all deaths, followed by heart disease, cerebrovascular diseases (stroke), and pneumonia, with aging-related conditions like Alzheimer's also rising due to Japan's aging population. While cardiovascular diseases (heart disease, stroke) are significant, cancer has been the top killer since the 1980s, with lung, stomach, and colon cancers being prominent.
Dermatologists recommend keeping your showers between 5 and 10 minutes. This time period gives you enough time to properly clean your body without overdoing it. If you have certain skin conditions, staying in the shower too long could have negative effects.
The Japanese 80% rule, known as "Hara Hachi Bu", is a Confucian principle advising people to stop eating when they feel about 80% full, not completely stuffed, to support health and longevity. This practice encourages mindful eating, helps prevent overeating, and is linked to lower rates of illness and longer lifespans, particularly observed in Okinawan centenarians. It involves slowing down during meals, listening to your body's fullness cues, and appreciating food as fuel rather than indulging to the point of discomfort.
The Japanese prefer to keep these two areas separate, reflecting a deep-seated cultural belief in the separation of “clean” and “dirty” spaces. To them, the toilet is a place associated with dirt, while the bathroom is a place for cleanliness and relaxation.
Drinking a cold, sweet, and (at the time) luxurious bottle of milk became the perfect way to cool down and treat yourself after a hot bath. The tradition became so ingrained in Japanese culture that it naturally spread to onsen towns like Beppu and became a nostalgic, essential part of the bathing experience.
Japanese tend not to eat while walking along or standing around on the street. However, it is acceptable to drink while standing aside vending machines, which are ubiquitous in Japan. Eating and drinking on local trains is also frowned upon, but not long distance express trains such as the Shinkansen bullet train.
Thanks to a historically weak yen, the U.S. dollar goes quite far in Japan, making food, local transport, and cultural sites surprisingly affordable, though high-end hotels and bullet trains still cost significantly in dollar terms; expect about 155-156 yen per dollar, allowing for cheap convenience store snacks, budget ramen for around $10, and museum entries under $5, making it a great value trip for U.S. travelers.
The Japanese 80/20 rule refers to Hara Hachi Bu (腹八分目), a Confucian teaching meaning "eat until you are 80% full," a mindful practice from Okinawa linked to longevity, where you stop eating before feeling completely stuffed to avoid overconsumption and promote health. It encourages slowing down, listening to your body's hunger cues, and leaving some space in your stomach, leading to lower calorie intake and reduced risk of chronic diseases.
In Japan, it is common to do laundry every day for couples or families. Single people typically do laundry 1 to 3 times a week. A family with small children will sometimes do it more than 2-3 times a day.
China, Japan, and Korea
In Korea, people prefer to take a bath in the evening after a long day of hard work to relax their bodies and ensure better sleep at night. However, Western cultures like those in the United States, Europe, and Canada prefer morning showers.
Hygiene and Health Reasons
Maintaining cleanliness is important in Japan for both practical and spiritual reasons. Regular cleaning helps prevent the spread of bacteria and disease, which can be a concern in a humid country like Japan. It is one of the reasons why mask-wearing is so common.
