Despite the rules and marketing policy that all rooms are non-smoking, this accommodation has left rooms deeply contaminated with toxic substances from tobacco (discovered in the spring of 2024). In Japan, in order to promote the SDGs and respond to such rule violations by guests, the Ministry of Health, Labor and Welfare provides information on appropriate measures to prevent damage caused by passive smoking, and information can also be obtained through the Internet. . Specific countermeasures shown in empirical research by the National Cancer Center include ozone treatment, air conditioner cleaning, floor cleaning, wallpaper replacement, and curtain replacement. Only by taking appropriate measures can we prevent health damage to users, and of course, to our employees. However, the owner of the property refused to take these steps. There was also a dismissive comment, saying, ``There are no lodging facilities on Iriomote Island that have installed ozone generators to prevent damage caused by passive smoking.'' In Honshu, cleaning using ozone generators is common in non-smoking accommodations. It is even used in accommodations where smoking is allowed. If what he said is true, there would be a large number of uninformed customers from overseas who value Iriomote Island as a world natural heritage site and come all the way to visit in order to experience immersing themselves in the natural world. This means that the entire island is being poisoned by cigarettes and being attacked. I will specifically discuss the contamination situation at the inn. The most contaminated area is the bed. It seems that he smoked while sitting on the bed. It is also believed that he slept in bed with his clothes still contaminated with harmful substances from tobacco. The level of contamination was so deep that it resembled a sofa in a smoking office where a mogul sits. The contaminated bed was covered with a polyester sheet and covered. However, in this humid area, the smell is constant every day, and when I try to remove the sheets and wash them, volatile toxic chemicals hidden under the sheets are released into the room all at once, leading to a high risk of breast cancer. Attacked a woman (who had used a non-smoking accommodation due to the risks). The indoor dryer emitted a cigarette smell when turned on. The toilet paper stored in the cupboard smelled of cigarettes and could not be used. I was so scared of the air conditioner that I ended up not using it. These accommodations should not be used by not only people who are at high risk of cancer, but also all people who spend their days living with other people. You will be poisoned. In addition, the nearby Super Yae supermarket has been transformed into a supermarket where ``waiting children'' stand around smoking cigarettes. The year is 2024. The store was filled with the smell of cigarettes. Diseases caused by the toxicity of tobacco = decrease in sperm count, ovarian disorders, endometriosis, uterine cancer, lung cancer, myocardial infarction, breast cancer, etc. In addition, washing clothes contaminated with toxic substances from cigarettes releases harmful substances into the ocean, causing cancer and teratogenic effects on sea life.
