Why do Japanese people in Japanese dramas drink bottled water bought in supermarkets?

Although tap water in Japan is completely drinkable, less than 40% people directly drink tap water (first line). In addition, 32% people put the water purifier on the tap before drinking (line 2), 29.6% people buy mineral water (line 3), and 27.7% people boil tap water (line 4). This survey is a multiple-choice question, so the sum of several categories of people slightly exceeds 100%. You can consider the result that people who drink tap water sometimes buy water to drink. ? The main reasons are as follows: 1, questioning the safety of tap water. It is clear that tap water can be drunk directly, but only 40% people can drink it safely. Another survey shows that 20% of Japanese people are uneasy about the safety of tap water (a very high proportion). Of course, this anxiety is similar to rumors or unnecessary worries. After all, in people's eyes, there are invisible things in food, and it is always more reassuring to spend money on packaged things. In Japan, you can often see advertisements of the Waterway Bureau, which publicize that the tap water in Japan has undergone strict quality control and the standard is much higher than that of mineral water. For example, the following one is very interesting: the packaging of bottled water says "tap water" The text next to it means "How about adding the water purification plant to the list of famous water sources in China?" This article mainly focuses on the taste of water, which means that tap water can be as good as mineral water in famous places. The lower left corner publicizes the safety and delicacy of tap water. ? This can also explain why so many people like to use water purifiers to filter tap water before drinking. Most of them are very simple filtering, and you can buy them in a hundred-dollar store. There are also cups with filtering function. There is no denying that there is also a marketing component. ? 2. Taste? The Japanese are very picky about the subtle taste of food and drink. There is no smell at all. It is also water without odor, but it can magically drink the difference between mineral water and tap water. It may have a psychological effect. Mineral water in Japan is not clean, but delicious from major water sources. For example, the water in Mount Fuji and Hokkaido, and some add some fruit flavor to make it taste better. Coupled with all kinds of "healthy" tricks, many people buy large bottles of water every day, but don't drink tap water.
