Yamamotoyama is one of the oldest and most established tea merchants in Japan. It has been the first to sell Green tea today. With the concept of Return to the origin of Edo, Nosigner have redesigned the packages to keep the traditional tea culture alive and pass it on to the future. To make them modern while retaining the charm of the long history brand, Nosigner referred to the traditional colors and structure of the scrolls with Yamamotoyama's original small crests and the calligraphy style of Edo.
