What is the meaning of 七五三 in the sentence, 七五三のしゃしんです。


I was looking at the following sentence under a picture that I unfortunately
cannot provide:

> 七五三のしゃしんです。

I believe the sentence reads "It's a picture of 753"... which doesn't make
sense.

I know that we have the numbers here 七 (7), 五 (5) and 三 (3). However, I don't
believe numbers are structured like this in Japanese, as far as I know.
Methinks this sentence is trying to say the number 753, but in Japanese,
wouldn't that be instead written as 七百五十三?

Am I wrong, am I merely interpreting this incorrectly, or is there another
problem I am overlooking? May someone please help me and correct me if I am
wrong?

ありがとうございます。




Just to make a proper answer, 七五三 (read “shichi-go-san”, _not_ “nana-go-San”)
refers to a traditional Japanese festival and is used in the literal meaning
“seven, five, three”. [From Wikipedia](https://en.wikipedia.org/wiki/Shichi-
Go-San):

> Shichi-Go-San (七五三, lit. "Seven-Five-Three") is a traditional rite of
> passage and festival day in Japan for three- and seven-year-old girls and
> five-year-old (and less commonly three-year-old) boys, held annually on
> November 15 to celebrate the growth and well-being of young children.

At a guess, the sentence refers to someone’s photo from this festival.

By the way, it’s not the case here but long numbers written out positionally
with Kanji for numbers (plus ○ for zero) without 千、百、十 etc. do happen in
Japanese (e.g. in price lists) although they’re rare in spoken speech AFAIK.
