I found some information tha may help out.
Village Background:
Hidden Rain is a lower shinobi village, being allied with Grass, Leaf, Sand and Waterfall. As such it participates in the Chuunin Exam with these countries. In the Chuunin Exam Naruto participated in, no Rain team made it beyond the second exam test. Hidden rain will do missions for countries outside its borders, with Wagarashi clan member Kyuuroku hiring Rain ninja to help him win the Todoroki shrine race in the Tea Country.
Country Background:
The Rain country is one of the mostly unrevealed lands in the series. The country appears to resemble most of the other countries, with forests dotting the landscape. It is unknown why the country is called rain; it may be due to seasonal showers which give the region more rainfall than other countries. The country shares borders with Earth, Fire, Grass, River, Wind and the Bird country.
Village Leader:
The current leader of Hidden Rain is unknown. Because it is a lower shinobi country, its leader can not call itself "Kage". (But really, in this guild, who really gives a care? You're still kage.)
Country Leader:
The current leader of the Rain Country is unknown, presumably it is a daimyo.
