有些时候我们认为这是极其自然的事情，但和世界各国相对比，你就会发现日本其实是一个很特殊的国家。冬季下雪，春天到夏天有很长的梅雨期。夏天酷热，有时有雷阵雨。秋天一定会有台风带来强降雨。因为日本的水源非常充足，所以日本人似乎不太在意水的珍贵。
     我在过去的40年中，对世界各地的自来水进行了调查。直到30年前，可以放心饮用生自来水的国家和地区除日本外，还有加拿大、阿拉斯加、美国西部的一些地区、北欧和新加坡等十几处。
     从高度成长期开始日本的自来水渐渐受到污染，要把被污染的水变成安全的饮用水，需要时间和金钱。可是，以往挥霍惯了的日本人还认为水是免费的。因此，还若无其事地继续污染着水源。日本人应该适可而止了，从现在开始必须重新认识饮用水的价值。

对自来水的不信任

     现在，矿泉水每年有1000亿日元以上的市场。人们逐渐用矿泉水取代自来水，不仅直接饮用，而且用来烹饪。矿泉水越来越深入我们的生活。这种现象的背后是人们对自来水的强烈不信任和对健康的重视。
     不仅是作为水源的河流等受到污染，净水厂使用的消毒用氯气造成的漂****味、致癌物质三卤甲烷的形成、输水管道和住宅小区贮水池的污染都是令人感到不安的因素。
     据民意调查，国民远离自来水的倾向越发明显。不直接饮用自来水的人达到近半数，女性、年轻人、东京和大阪等都市生活者不饮用自来水的概率越来越高。
     20～30岁年龄层的女性中，不饮用自来水的占50%。而如果只计算居住在东京23个区和12个政令指定城市的30～35岁的女性，将近9成都回答不直接饮用。这个年龄层的女性多数正在养育自己的孩子，因此对水的味道和安全性更加敏感。
     男性中直接饮用自来水的占55%，高于女性，特别是50岁以后的男性居多，占到了60%左右。另外，不同城市规模分别统计的结果显示，城镇居住者中直接饮用自来水的占63%。这也许是因为地方自来水的水质比城市好的缘故。
    不直接饮用的人一般是煮沸饮用或沏茶、冲咖啡。另外根据这次调查，"使用康来泉家庭净水器"的人占总数的29%，在不直接饮用的人中占47%。净水器的销量在近11年中增长了11倍。大城市的居民中有45%使用净水器，而乡镇居民中使用净水器的只占17%。
     购买矿泉水的人也占38%。和净水器一样，城市的购买比例大。乡镇的比例仅为23%，大城市为54%，而东京则超过了60%。

       是什么原因让净水器行业走的越来越好呢？

     Sometimes we think this is a very natural thing, but the countries in the world and the relative ratio, you will find that Japan is a very special country. The snow in winter, spring and summer for a long period. Summers are very hot, sometimes a thunder shower. Autumn will be brought by the typhoon heavy rainfall. Because the water is very abundant, so the Japanese did not seem to care too much precious water.
    I in the past 40 years, the world's tap water was investigated. Until 30 years ago, can rest assured drinking raw water of the countries and regions except Japan, Canada, Alaska, the United States some of the areas in the west, northern Europe and Singapore more than 10.
   From the height of long-term to Japanese tap water is polluted, the contaminated water into safe drinking water, need time and money. However, previous waste used by the Japanese think water is free. Therefore, even to pollution of water sources. The Japanese should not overdo sth., from now on, to recognize the value of drinking water.

On the water does not trust

    Now, mineral water each year more than 100000000000 yen market. People gradually with mineral water instead of water, not only directly drinking, and used in cooking. Mineral water is more and more deeply into our lives. The backside of this kind of phenomenon is people to tap strong distrust and an emphasis on health.
    Not only as a source of rivers are polluted, water purification plant using disinfection with chlorine caused by drift * * * * taste, the carcinogen three halogenated methane formation, water pipelines and residential district reservoir pollution are disturbing factors.
     According to the polls, national away from the water tendency is more obvious. Not directly drinking water to nearly half, women, young people, such as Tokyo and Osaka city life not drinking tap water, the probability of getting high.
    20~ 30 years old age women, not drinking water for 50%. If the calculated only live in Tokyo23district and 12designated city30 ~35 year old female, nearly 9Chengdu answer not drinking directly. This age most women are raising their children, so the water taste and safety more sensitive.
    Men drinking tap water directly accounted for 55%, than females, especially after the age of 50male predominance, accounted for about 60% of. In addition, different city dimensions respectively, statistics show, urban residents drinking tap water directly accounted for 63%. This may be because the local water quality is better than the city.
    No direct drinking person is generally boiled drinking tea, or coffee. According to the survey," the use of household water purifier" people accounted for 29% of the total, without direct drinking people accounted for47%. Water purifier sales in the past 11 years has increased 11 times. City residents in 45% using the water purifier, and township residents use water purifier accounted for only 17%.
     Buy mineral water were also accounted for 38%. And the water purifier, the purchase of large city. The township was only 23%, big city of 54%, and more than60% tokyo.
What is the reason for the water purification industry go better?
