A friend commented on the last post about what was said on the shirt. My response became kind of lengthy, and I don't know if you find languages fascinating like I do, but just in case, here's my response to the question:
The top of the shirt says, literally: "Morumon herupingu hanzu" (Mormon Helping Hands). The bottom is "Matsu Jitsu Seito Iesu Kirisuto Kyoukai"--The Church of Jesus Christ of Latter-day Saints.
Japanese has three writing styles. The top writing is written in katakana. It's used for words adopted from other languages. That's why it's so easily understood once you know what the characters say--they're all syllabic. It's kind of like a secret code.

Hiragana is the same way as far as being syllabic goes, but it's not quite as pointy as katakana. It's used for Japanese words and is much more easily read than the Chinese kanji characters. There aren't any hiragana characters found on this shirt.

I don't know much, so there's probably someone out there who knows a lot more than I do about this kind of stuff, but there you go, a basic lesson on Japanese.
