Kencho-ji Temple, Kamakura, Kanagawa Prefecture, Japan — attributed to 13th century Chinese monk Rankei Doryu; shojin ryori origin; adopted as regional winter comfort food throughout Kantō region
Kenchin-jiru (けんちん汁) is a hearty Buddhist vegetable soup of Kamakura region origin — a clear or miso-seasoned broth filled with root vegetables (gobo burdock, daikon, carrot, renkon lotus), tofu, konnyaku, and sometimes shiitake — all cut into bite-sized pieces and sautéed in sesame oil before simmering in kombu dashi. The soup takes its name from Kencho-ji Temple (建長寺) in Kamakura, where 13th-century Chinese monks are said to have created it from broken tofu and vegetable trimmings — a mottainai (waste-nothing) origin story that aligns perfectly with shojin ryori vegetarian ethics. The sautéeing step before simmering is the technical distinction — the vegetables are briefly cooked in sesame oil before liquid is added, developing flavour through light caramelisation and ensuring the oil carries the sesame fragrance through the soup. Kenchin-jiru is a winter dish — hearty, warming, deeply seasonal in its root vegetable composition. It is one of Japan's most complete nutritional one-bowl preparations: the root vegetables provide fibre, tofu provides protein, konnyaku adds texture, and the sesame oil provides essential fat. It appears at temple restaurants, in mountain areas during winter, and is a standard school lunch item in Kamakura-area schools.
Warm, earthy root vegetable depth, sesame oil richness, light clear broth — the taste of Buddhist simplicity and winter nourishment
{"Sesame oil sauté first: all vegetables and tofu are sautéed in sesame oil before any liquid is added — the fat distribution and light caramelisation is the flavour foundation","Root vegetable cutting: hyogiri (thin diagonal rounds) for gobo and carrot; icho-giri (half-moon) for daikon; bite-sized but not too small — they must hold shape in extended simmering","Konnyaku: hand-tear rather than cut — the rough surface absorbs broth better; also follow with brief blanching to remove konnyaku lime odour","Tofu: firm cotton (momen) tofu, torn by hand into rough pieces — the rough texture absorbs broth as it simmers","Seasoning: light soy sauce and salt (shojin ryori version, no animal products); or miso added at the end for home versions — always taste before final seasoning","Serve hot with rice: kenchin-jiru is a meal in itself alongside plain rice; volume portions should be generous"}
{"Kenchoji Temple in Kamakura serves a shojin ryori lunch (advance reservation) — eating kenchin-jiru at its place of origin is a historical food experience","Warming quality: a small amount of grated ginger added in the last 2 minutes of simmering adds warmth without disrupting the clear broth character","Seasonal adaptation: spring kenchin uses bamboo shoot, spring turnip, asparagus; autumn version uses mushroom (shiitake, maitake), chestnut, kabocha","Leftover kenchin: add cooked rice to the remaining soup and simmer 5 minutes — produces a warming, complete rice porridge (zosui) from the enriched vegetable broth"}
{"Skipping the sauté — adding vegetables directly to broth without sautéing in sesame oil produces a watery, flat soup without the characteristic richness","Cutting vegetables too small — tiny cut vegetables dissolve and lose individual character during simmering; bite-sized and substantial","Over-seasoning — the vegetables release their own sweetness; under-season initially and adjust after 20 minutes simmering"}
