Guthrie asks if anything else if different since we were in the UK. Aircon!
While it is very pleasing to us Japanese that the silly English (oh no I've given away the country we are in!) are buying our beautiful, efficient aircon, they really need to learn to leave them switched off until it is at least warm. The one in the photo (Toshiba - hurrah!) isn't actually on, thankfully, or we wouldn't have stayed so long in the pub, but we have several times been in coffee shops, where it is cold outside (under 20C) and even colder in the shop itself, such that we didn't really enjoy having to hang about and drink the coffee. This seems to me to be the opposite of adapting to temperature increase; spending more money on electricity to keep the temperature lower than it has ever been. Seems the Japanese are doing all the "gaman" on this; going to work almost naked and keeping their aircon at 28C. Of course, it is true that a lot of electricity is used in Japan on aircon - it hit 38C in Tokyo yesterday, which means that even aircon set to 28C would be struggling.
