Yu no Kuni
Yu no Kuni; The Country of Hot Water
Yu no Kuni, also known as 'The Country of Hot Water' or 'Hot Springs Country' is a country that existed during the time of Uzumaki Naruto and is well known as one of the primary countries that the Fourth Great Shinobi World War was fought in. The country is named for it's many hot springs and geysers that dot it's landscape, causing the nation to become an ideal vacation spot due to it's natural assets.
Economy
Unlike most modern countries with shinobi villages, Yu no Kuni's military is not even close to the primary source of income for the nation. Instead, the country thrives on being the go-to vacation spot thanks to it's natural hot springs, towering geysers, white sand beaches, and rich history.
All manner of resorts and hotels dot the landscape, bringing in citizens from all over the world to enjoy an atmosphere in which they can decompress without the worries of every day life. There's a little bit for everyone in this country, and thanks to it's location between Hi no Kuni, Denchi no Kuni, and Rai no Kuni, there is no shortage to new vacation goers, bringing in diversity from all over. It is not uncommon to even see citizens from Mizu no Kuni organizing luxury 'cruises' between the two nations.
Recent happenings such as the rise of the NCIA and subsequent fall did nothing to harm Yu no Kuni's economy thanks to Yugakure's decline as an actual shinobi village during the time of Uzumaki Naruto. If anything, the sudden economic surge during the time of the NCIA only helped to bring in more customers than usual.
Architecture
In the majority of the outlying farm villages and towns, the Country of Rain has no particular major 'leaning' in architectural styles, but it's older buildings are distinctively Japanese and eastern Asian. Within the larger cities there are many newer buildings that are almost 'modern' in their styling, just as is true of the City of Tin. In Amegakure no Sato, the largest city in the entire small nation, there are many, many tower style buildings with modern piping and architectural style. Pipes flow in and out of the major cities as the control of rain flow is incredibly important and crucial to survival in the harsh environment. Many of the street sides and buildings are covered in these pipes which redirect water to safe sewers, many times larger than other villages as the average rainfall per year, or even per day, exceeds the needs of anywhere else in the known world.
Terrain
The Country of Rain is varied, as many countries on the known continent are, and has hills, forests, and streams dotting it's landscape, along with villages scattered about and wide rice fields, and farms in the -few- areas to the North which are high enough to not be caught in the 'rain shield' Ame no Kuni suffers from because of the Mountain Range in Kaze no Kuni below it (Which keeps the Desert from encroaching) and the mountains of Tsuchi no Kuni to the North, the former of which sends warm air into Ame no Kuni, and the latter of which sends cold air most of the time into Ame no Kuni, leading to a high precipitation, heavy rainfall environs, which though varied, is almost always effected by rainy weather.
Culture
The life in Ame no Kuni is about as unforgiving as the rain that plagues it. As an industrialized nation, the mentality of the land is constant growth and advancement, even at the sacrifice of one's neighbor. That's not to say relationships here are hard to find and blandly cold, for the bonds that survive in this wasteland turn out to be for life. This land is all about fashion and they even developed ways to keep re-breathers in style. Depression and suicide rates are high and also are the influx of artists and dancers. People often carry umbrellas with the same gusto as one feels about their wallets and keys. Those umbrellas usually double for a weapon in disguise.
Weather
Rains are common throughout most of the year, and cold weather and warm weather otherwise fluctuate at fairly normal temperatures.
Transit
Much of Ame no Kuni is traveled by foot or by farmer's cart, because of the poorness of much of the country, though there are a rare few who use the Train extending from the Coal Country to Ame no Kuni. As well, river transit is very popular amongst the citizens. Small boats can be seen traveling up and down the river, taking trade goods and people from one destination to another. The large amounts of rainfall makes healthy rivers all year round as a reliable travel means.
Amegakure no Sato, Capital of Ame no Kuni
Amegakure no Sato has always been at ends with Konohagakure no Sato since the creation of the Hidden Villages. The animosity still holds true today, although they kindly extend their swords to the throats of other nations. The Capital of Ame no Kuni warrants that not only does this place receive the highest dosage of rain in the land, but it's the one greatest touched by technology. If its size were not minuscule compared to the other villages, then Amegakure no Sato could have been the seat of world dominance. Though this is not the same village of the old Amegakurean people, the mentality and menace still holds true.
Some still whisper that the rain that falls in this village has ethereal proprieties. Its largest claim to fame, however, is that it is where most of the world's technology is researched and created. The country's industry relies almost entirely on the export of machines, and its population is an astounding 32% made up of certified engineers, with yet more mechanics and tinkerers. If you want technology, you go here.
