Fukamushi (深蒸し, "deep steaming") is a 20th-century Shizuoka regional innovation that has become one of the dominant Japanese sencha styles nationally. The technique extends the steaming step substantially — 60 to 120+ seconds vs the 30–40 seconds of standard sencha — which breaks down the leaf cell walls more thoroughly and produces tea that infuses faster, brews into cloudier bright-green liquor, and tastes meaningfully smoother and sweeter than standard sencha. The longer steaming also fragments the leaf, so fukamushi sencha appears in shorter, broken pieces rather than the long needle-form leaf of standard sencha.

The Makinohara plateau in Shizuoka — Japan's largest single tea-producing area — pioneered fukamushi in the mid-20th century to address a regional challenge: the Makinohara terrain produces fuller-bodied, more astringent sencha that traditional asamushi (light steaming) couldn't soften adequately. Extended steaming created a more accessible cup character that became popular nationally. Many drinkers today prefer fukamushi to standard sencha for its smoother, sweeter approachability. Traditionalists argue fukamushi loses some of the aromatic complexity that lighter steaming preserves. Both positions have merit; both styles remain widely produced.

Moderate complexity
Standard skilled production. Established techniques.

Key processing steps

  1. Hand or mechanical harvest
  2. Extended steaming (60–120+ seconds, vs 30–40s for standard sencha)
  3. Rolling — leaves break into smaller fragments due to extended steaming
  4. Shaping and drying cycles
  5. Final firing
