Why is there an unmatched parenthesis in this title?


This Asahi Shinbun article has an unmatched right parenthesis in its title:  
[岩手）震災の教訓を考える
「人間復興大学」１０日開学](http://www.asahi.com/articles/ASG4S51M0G4SUJUB00B.html)

Surely, Japanese syntactic rules disallow unmatched parenthesis, right?  
Asahi Shinbun just made a mistake (in a title no less), correct?




It's not a mistake, it's just a stylistic choice. They do it all the time:

I only spent about 30 seconds looking through headlines to find these examples
--I'm not picking out anything rare. You've probably noticed that each one
"tags" the article with the name of a prefecture:

> 長野県（ながのけん）  
>  愛媛県（えひめけん）  
>  岐阜県（ぎふけん）  
>  青森県（あおもりけん）  
>  茨城県（いばらきけん）  
>  岩手県（いわてけん）

Your example "tags" the article as being relevant to 岩手県.
