Yatachi

Yatachi [上岔; やたち] is a city located in southen Heisai Prefecture on the border with Kigen Prefecture. As of 2020, it had a population of around 29,000. 
The city's area is taken up mostly by the Tsuba mountain range, and only around 15% of Yatachi's designated land is dedicated to inhabitance. Two large peaks are included within Yatachi - Mount Kayo and Mount Eku, the latter of which serves as the source of the Kugai River. The rest of the rocky, steep land is used for mining and the processing of stone and minerals, which is one of Yatachi's main industries. The Kanton Oil Storage Company also operates a large underground petroleum storage facility in Yatachi. Some agriculture is carried out in Yatachi, mostly centering around root vegetables and low-maintenance crops. Mountain goats are also reared.
Yatachi is famous for its deposits of amber which date from millions of years ago. Interestingly, Yatachi is one of the only places in Kanton where amber has been found, and noted examples can be viewed at the Yatachiemi Museum. In the surrounding cities, Yatachi is sometimes colloquially known as Emido, or 'amber town'. It was, in fact, known officially by this name up until the 1830s when its moniker was changed to Yatachi by the prefectural government.
