34 degrees was the average temperature for my part of Western Japan this year, with about 85-90% humidity. Heat is good, humidity less so – it makes the city something akin to a concrete swamp. Air conditioning gets turned up, the carbon footprint of the country increases a hundred fold. Not sensible levels of air-conditioning, but down to levels where, if it were winter, they would turn on the heating.
Japan prides itself on being close to nature, and having four distinct seasons. Each season has its own particular “kisetsu” foods, drinks and symbols. Such things as chestnuts , along and the turning of the leaves of autumn are celebrated much more than say in England. But one can’t help that with the advent of the air conditioner, that the Japanese are trying to ignore the very differences of nature that their ancestors celebrated. When everything is 25 degrees celsius, the passing of the year becomes less noticeable and more unimportant.
Not just food is considered a symbol of the seasons though. Animals are also. Cicadas for summer, frogs for the rainy season, bears for winter. These kisetsu symbols helped mark the passage of time when nature played a much more important part of Japanese life than it does today.
Of the more interesting kisetsu symbols is the cockroach. A kisetsu symbol for summer, subject of many a haiku poem, and as elsewhere a virulent pest. Hot weather and humidity are something like cockroach heaven, and they spring up in their millions in Japan in the summer. In the UK, cockroaches are only associated with the kind of uncleanliness that takes effort to achieve. In Japan they are everywhere. As long as my thumb, and wider, they seem to find ways of creeping into even the cleanest and newest apartments. Since cockroaches can digest plastic bags and the pages of books, there really is nothing they won’t eat, and with the humidity encouraging them breed at pace, you really are stuck in a war of attrition.
Japanese shops are well stocked with things to help rid yourself of the little vermin, a variety of sprays and repellents on sale. Sprays kill the things dead in seconds, but rely on you actually being able to corner the cockroach first – not an easy job. My personal favorite cockroach control device is the cockroach hotel – an open cardboard box with a cockroach attractant placed in the middle of a patch of super-strong adhesive. The cockroach enters the hotel, toward what it hopes is lunch and ends up literally stuck to the floor. Which of course is where you find it the next morning, looking at you, feelers bicycling in a most evil way while you try to find the courage to get near enough to lever the hotel into the trash.
Anyway, whichever method you use, you are most likely fighting a losing battle: Apparently for every cockroach you see there are 90 more hiding in nooks and crannies. Wikipedia even notes that cockroaches are so hard that they are even immune to the kind of radiation that emits from a nuclear blast, which begs the question: What the hell is going into the cockroach spray?
