The Uji Tea Museum opened in 2017 as the first institution in Japan dedicated exclusively to documenting the 800-year lineage of Uji tea cultivation, a craft that supplied imperial courts from the Kamakura period onward. Located in Todoh, a district where stone-grinding mills once lined the Uji River, the museum occupies a contemporary timber structure designed to echo the proportions of Edo-period tea warehouses. Its permanent collection spans 400 artifacts, including Genroku-era ceramic tea jars, nineteenth-century iron grinding wheels, and signed correspondence between Uji tea merchants and Tokugawa shoguns. Uji's matcha production hinged on three technical innovations introduced between 1200 and 1600: shade cultivation under reed canopies to concentrate chlorophyll, stone-grinding at precise rotational speeds to preserve volatile compounds, and quality grading systems that assigned poetic names to harvest batches. The museum's galleries trace each innovation through working replicas and archival records. A matcha grinding experience and walking tour in Uji Kyoto begins in the demonstration hall, where visitors use granite mills identical to those employed by sixteenth-century tea masters, grinding tencha leaves into powder fine enough to suspend in water without sediment. The museum's walking circuit extends beyond its walls into the surrounding Maruyama district, where heritage tea fields still operate under traditional shade structures. Interpretive markers identify the cultivars planted in each plot and explain seasonal pruning cycles. The route passes the stone foundation of a Meiji-era tea processing facility and concludes at a riverside overlook where boats once transported tea casks to Osaka markets. Museum admission is 600 JPY per person, with hours from 09:00 to 17:00 daily. Workshops integrate hands-on grinding sessions with guided neighborhood walks, connecting museum artifacts to the living landscape that produced them. The experience roots visitors in the material realities of Uji's tea economy, from soil chemistry to imperial patronage networks that sustained the industry across centuries.
