When I'm travelling in a foreign country where I don't speak the language I'm always on the look out for English signs to guide my behaviour. They tell me things like where my track is in the train station, whether the water is drinkable in the hotel, or in Japan (especially), how to use their extraordinary toilets. In some signage the English is perfectly understandable, other times I'm left wondering what I'm expected to do. And sometimes I admit to laughing out loud because the translation as I understand it is downright humorous.
When I last visited Japan I took photos of many signs I encountered. I think you'll agree that most are helpful, some offer interesting insights into the culture and some will definitely make you giggle.
