On March 1st of 2006, the towns of Kaya, Iwataki and Nodagawa merged to be reborn as the Town of Yosano. The new town is located in the Tango region of Northern Kyoto Prefecture near the Sea of Japan, and borders on the cities of Fukuchiyama to the South, Miyazu to the East, Kyotango to the West, and the mountains of the Tango Peninsula to the North. The town spreads from the Oeyama mountain range and extends through the fertile fields of the Nodagawa river basin, and continues to the beautiful views of Amanohashidate.
The Town of Yosano covers a total of 107 square Km (41 square miles), stretching approximately 20 Km. (12 miles) from North to South, embracing several town centers and villages with a combined population of approximately 25,000 people.
The climate is complemented by all four seasons; Spring brings the first green of the year, Summer sees fields of sunflowers and herbs, Autumn paints shades of yellow and gold to both the rice fields and the leaves, and Winter carries showers on North-Westerly winds that characterize the heavy rainfall along the mountainous coast of the Sea of Japan. All four seasons in the area promise beautiful views of the sea and flowing rivers also.
With prosperous exchange with the mainland and the Korean Peninsula through the Sea of Japan, the area is said to have once been the "front" of Japan, a reference that now refers to the Pacific coast. The area is comparable to other archaeologically significant regions such as Izumo or Etsu, with proof of ancient civilizations ranging from glass bracelets from the Yayoi period (500 BC - 300 AD) to countless iron swords found in Iwataki at the Oburominami tomb site. The remains of the Ebisuyama tomb mounds in Kaya are one of the three great tomb mounds in the Tango region and designated as national treasures. The distribution of these precious ruins leads to speculation that the leaders of the ancient Kingdom of Tango resided in this area.
In more recent years, the region became known as the "Gateway of Tango" through its thriving shipping industry, and also developed many close ties with prominent literary figures including Buson Yosa, the new town's namesake. The area is now most recognized for its Silk crepe known as "Tango Chirimen", which dates back to the Edo period and influential silk weaving kagyo (traditional family business). The talented Saheiji family in nearby Mineyama invented a unique Chirimen with an intricate texture based on the silk weaving techniques of Nishijin District of Kyoto. Through the notable efforts of the families Tegomeya Koemon in Kaya, and Yamamoto Sahei in Nodagawa, the popularity of Tango Chirimen spread. Within the Tango region, the Yosano area is still the most active in keeping the Chirimen industry alive.
