The Japanese appear to be a quiet, reserved race. In stark contrast, a walk down the road can result in a complete auditory and sensory overload. ATM's, elevators, doorways, toilets, trains, trams, all talk to you. Loud speakers blare from stores and cars passing by.
Tokyo is the cleanest city I have ever been in. There is never any litter or rubbish on the ground, yet there are no rubbish bins anywhere.
Hot carpet - Rugs with a heating element under them. They totally rock.
The screens on ATMs and metro ticket machines show an image of a woman bowing before and after you use the facility. Even the machines are polite.
All doors open outwards to ensure you don't get trapped in the event of an earthquake. Very strange to pull the door out when walking in your front door at the end of the day, or walking into the bathroom.
5 o'clock bell * - no matter where you are in Japan, bells peal out at 5.00 pm seven days a week, 365 days a year, in perfect unison, as time is something you just don't mess with here.
GG now has a huge, annoying handbag that hangs off the crook of her elbow. :-o
*Update: um, except the bell now goes off at 6.00pm. Something to do with spring and summer. Ah!
