Returning to Japan, he was selected to lead a restaurant in Toyama Prefecture, located in a riverside resort in the countryside. By 2014, Taniguchi took full ownership of the restaurant, renaming it Cuisine Regionale L’evo, symbolizing his philosophy of evolution in cooking. This became the foundation for his innovative dishes that would define his culinary style.

In the following years, Taniguchi’s talent gained recognition as he garnered praise for his forward-thinking approach. However, he soon began planning a new chapter, envisioning a space where guests could stay and fully experience nature alongside his cuisine. This vision came to life in December 2020 with the opening of the second L’evo at the site of an abandoned hamlet. Despite being open for a short time, the restaurant quickly earned two Michelin stars in the 2021 guide, along with a Green star for sustainability. L’evo has since become a renowned destination for food lovers, offering a unique culinary and natural experience far from the city.
