About Sonogi Tea
The environment in which Sonogi tea is grown
A unique taste developed in a climate ideal for growing tea.
Higashisonogi Town faces the calm waters of Omura Bay and is home to a peaceful rural landscape.
The tea fields are located on the slopes of the mountains, where a refreshing sea breeze blows through.
The temperature difference between day and night is large, and morning mist rises in the spring.
The abundant water from the Tara Mountains nurtures high-quality tea leaves, creating a unique flavor.
