sha/sya same thing...romaji isn't an indefinate as far as spelling goes

example:

tsu and tu
or
shi and si

different styles of romanization but the same thing :mtongue:

asking permission to take a pic

"Is it O.K. if I take a picture?"

If you want to use keigo (honorific) form, say "Shashin o totte yoroshii desu ka?" But, considering it's a casual, everyday event featuring a lot of young people, just use "ii."

HORA KONOYARU KOCCHI MITTE, IMA SHASHIN TOROUN DA sometimes works too

Do you think one of you can write it to i can say it. im not good with letter sounds.

sah-sheen toe-tay e des kah

LMAO I love coming up with the most impolite ways to say things, just for laughs. You beat me to it >.<

Althought, I think they'd just run away XD

Shyah-sheen toe-teh ee dess kah?

I got the impression it was similar guidelines to cosplayers at an anime convention - if people are clearly in costume they most likely won't mind you taking photos of them, but they'd probably prefer that you ask first so they can pose and give you a good picture :) Don't be afraid to ask though, all the people I asked to take photos of on that bridge were very obliging and nice. Apparently the cosplayers mainly come out on a Sunday though, so remember to go on the right day!

I saw more tourists in Harajuku than anywhere else I went in Japan, so I'd bet the regular cosplayers are very much used to tourists who can't speak Japanese. If you hold up your camera and just say 'okay?' they'll probably figure out what you're after.

I'm just giving you a hard time over your dialect :D Kansai or Kanto, I'm not sure which
