EU demand for Japanese product is mature, not new
Unlike the US — where the matcha boom and the wagashi-confectionery wave feel recent — Japanese ingredients have been on EU specialty shelves for two decades. What's changed is mainstream retail penetration: matcha-flavoured chocolate at Lidl, yuzu candy at Tesco, miso at Carrefour. The premium specialty buyer base remains active (Michelin restaurants, J-beauty retailers, organic chains) but the mainstream channel is now where the volume is moving.
The EU regulatory framework has also matured. EU-Japan EPA (effective 2019) eliminated tariffs on most foods over a phased schedule. Organic JAS is recognised as equivalent to EU organic. The cosmetic regulation (Reg. (EC) 1223/2009) provides predictable INCI / CosIng-driven access for most established Japanese ingredients.
