Increasing momentum toward tea cultivation in Nishio

 In mid-19th century when Japan was opened to the world, major export goods was raw silk and tea. In midst of such background, there was movement to develop the tea business in the Nishio region, which is blessed with a natural environment of good water quality, soil, and weather that is suitable for producing tea. During this period in 1888, the first president Sugishita Aijiro found Sugishita Shoten, a tea and indigo plant production company.

Nishio Tea aimed for high-quality tea from the beginning

 The feature of Nishio Tea founded in early Meiji era was that they aimed to produce high-quality tea from the very beginning. This was the start of the foundation for good tencha production, which later became the raw material for matcha.


Improved quality, enhanced technology and expanded channels

 In 1904, the Hazu-gun Seicha Doshikai was organized with tea field owners of Kamimachi (where AIYA headquarters is located). The organization has been taking initiatives for the tea production business by holding tea fairs and conducting tea production training programs for improved technology. Technology and quality for high-class tea was further improved and sales channels were expanded. Customers expanded from within the prefecture to Kanto and then to Kansai areas.

Shifting from gyokuro to tencha of a higher value

 Tea producers in the Nishio area including Sugita Shoten, aimed to produce gyokuro with higher commercial value. They established a cultivation technique of covering the tea trees before harvest.


From tea and indigo to tea only

 Aiya Tea Store Limited Partnership Company was established in 1922. When the appointment of the second president, Aijiro, the indigo production and sales that started since early Meiji era was discontinued and the company focused on tea production, and made efforts to improve tea production technology and to expand sales channels. During this time, Nishio Tea genuinely started to change from gyokuro to tencha.


Reinforced organization and increased production due to focusing on tea only

 Focusing on only tea, reinforced the organization in many aspects. Productivity increased by constructing a new office building and tea production factory. After the Mikawa tencha machine was invented in 1930, production increased and Nishio developed dramatically as a matcha producing area.


Tea production survived in the Greater East Asian War and the Tonankai earthquake

 At the end of the Greater East Asia War, tea fields were hit by a crises of having to convert the fields for growing potatoes and wheat which will serve as food. In addition, the Tonankai earthquake occurred in December 1944 and the Mikawa earthquake occurred in January 1945. Nishio-shi was near the epicenter and was hit by a seismic intensity of 7. The office building was completely destroyed. The war ended in August 1945. The tea producers in Nishio continued to produce good tea in spite of their suffering. Four years later, contracting tea field area exceeded 70 hectares and tencha production grew stably.


Production capacity boosted along with reconstruction

 In 1950 when Japan was in the reconstruction mode, AIYA Limited was established. The third president, Aijiro, inaugurated and boosted production capacity.


New path to food processing material found

 Challenged new market development in around 1960. A new path was found by changing the fixed idea of matcha as a drink. The company aimed for the expansion of sales channel for matcha as a food processing material.


Production of the first organic matcha begun in Japan

 The third president Aijiro cultivated tencha fields in the mountains of Toyota-shi, Aichi-ken (formerly Shimoyamamura). There, efforts were made to produce Japan's first organic matcha, which at that time was considered very difficult. The tencha fields were destroyed over and over again from pests, rain and the sun. The forth president Aijiro realized the organic matcha both human-friendly and environmental-friendly.
