I've always wanted a t-shirt with some Japanese writing on it. Unfortunately people over there only want English on their shirts.
But under a bridge in Ueno I came across a young lad selling T-shirts with Japanese symbols on them. Casually I picked one up, hoping it didn't say "English Tosser" or something.
Good job I checked. The lad provided me with a A4 laminated sheet of translations and apparently the one I had picked said "I am a foolish man". Hastily I chose another only to discover that it said "I am an idle man".
I settled on one which says "Yamato Damashi" or "Spirit of Japan". This pleased the man at the passport desk in Narita who, on seeing my T-Shirt, livened up no end.
"Haaaaaaa! Yamato Damashi" he said pointing like a madman. I think I made his day.
