Arita-san uniquely preserves the traditional finishing method of carefully heating the tencha using Japanese binchotan charcoal instead of gas or electricity. Once standard throughout Kyoto, this technique has all but vanished, replaced by modern machinery and cheaper fuel sources. In addition to the charcoal drying, Arita-san also sifts, sorts, and cuts his tencha the old-fashioned way: by hand using metal and bamboo screens. Having toured multiple matcha finishing facilities, I can say with certainty that Arita-san's is the most unique, with bamboo, wood, and washi being the dominant materials instead of industrial machinery.
