Kyoto, Japan — Kikunoi has operated for over a century; Yoshihiro Murata represents the third generation. His international advocacy work began in the 1990s and culminated in the 2013 UNESCO inscription of washoku.
Yoshihiro Murata of Kikunoi, Kyoto (three Michelin stars), is Japan's foremost ambassador of washoku internationally and a leading force in its 2013 UNESCO recognition as Intangible Cultural Heritage. Where other kaiseki masters guard their traditions within Japan, Murata has lectured globally, co-authored research with food scientists, collaborated with Ferran Adrià, and written extensively about dashi science. His landmark work is demonstrating that umami (glutamate-inosinate synergy) is the scientific foundation of Japanese cuisine — not a mysterious tradition but a reproducible, teachable chemistry.
Murata's flavour philosophy centres on dashi's umami foundation — every dish at Kikunoi is designed to maximise the glutamate-inosinate synergy that Japanese cuisine discovered empirically over centuries. His contribution is making this synergy legible and reproducible, so other cuisines can understand why Japanese food achieves its characteristic depth with so few ingredients.
Murata's technical contribution: he was among the first Japanese chefs to quantify dashi preparation — measuring temperature, time, and ingredient ratios with scientific precision rather than intuition alone. He collaborated with umami researchers to document that the synergistic effect of glutamate (kombu) + inosinate (katsuobushi) is up to 8× more powerful than either alone. He developed reproducible dashi protocols that can be taught cross-culturally. His kaiseki menus at Kikunoi demonstrate that washoku's apparent simplicity conceals extraordinary biochemical complexity.
Murata's international lectures demonstrate that chefs from any tradition can understand and apply Japanese dashi science — French chefs recognise it as related to fond; Spanish chefs relate it to sofregit umami-building. His collaborations with Adrià produced dashi-based gels, foams, and modernist applications. The key insight: washoku's restraint is not simplicity but precision — every element stripped to reveal the maximum expression of the ingredient's natural chemistry.
Treating dashi as a simple background element — Murata argues it is the primary flavour architecture. Using inferior kombu or katsuobushi and expecting the technique to compensate — the ingredients are the science's raw material. Misunderstanding umami as 'savouriness' — umami is a specific receptor response to glutamate/inosinate; not all savoury foods are umami-rich.
