Unagi Culture — Eel Traditions and Kabayaki Mastery
Tokyo (Edo) and Osaka, Japan — kabayaki tradition from Edo period (17th century)
Unagi (freshwater eel, Anguilla japonica) occupies a singular position in Japanese food culture — historically the most labour-intensive restaurant preparation, associated with summer stamina (doyo no ushi no hi, the midsummer 'day of the ox' when eel is traditionally consumed for its fat-rich, stamina-giving properties), and supported by a highly specialised craft tradition. The kabayaki preparation (split, skewered, steamed, then grilled over charcoal with repeated tare applications) is so specific that unagi restaurants are essentially single-dish specialists — the itamae trains for years to master the cutting, skewering, steaming, and grilling sequence. Three regional styles: Tokyo-style (split from the back, steamed before grilling, placed over rice — unaju); Osaka/Kansai style (split from the belly, no steaming, more crispy texture); Nagoya hitsumabushi (shredded eel over rice in a wooden tub, served three ways). Unagi is currently listed as Critically Endangered (IUCN) — sustainable sourcing is an urgent consideration.
