UPDATE!
woah..it's been two years! *haha* ii would like to share about toilets too. They are pretty clean everywhere..However, I never been to the public toilet yet.
The Traditional/Old-fashioned Toilet:
The Modern Toilet: When you open the door, the lid will automatically open for you. And it has a function of auto-flush (if you're being lazy) after 1-minute standing infront of the toilet seat. Then, there's buttons for you to lift up/close the lids or the seat-thingy. The type is similar as shown by the OldDude. Most toilets in Japan are now westernized for both Japanese & Gaijin comfort. Another best part, if you dont use the toilet anymore and you walked away. The toilet will half-flush itself again & automatically close the lid! Awesome!
The Modern Toilet's Instructions:
Typical CHILDREN toilet - Shared (Male/Female)It's amazing to see these cute little toilets made for the children. This toilets are usuaully found in kindergarten/nursery schools.
