A Taste of Japanese Kindness. 100% Gluten-Free.
Welcome to C'est du nanan. We are an artisanal Japanese pastry shop dedicated to crafting exceptional sweets from one extraordinary ingredient: Japanese rice flour.
In Japan, rice is more than sustenance — it is a cultural treasure, spoken of with reverence as Okome. We've taken this cherished tradition and blended it with global patisserie techniques to create sweets that are not only delicious but naturally 100% gluten-free.
Experience a unique fusion of Japanese tradition and modern pastry, handcrafted with kindness and care.
The Perfect, Guilt-Free Souvenir
Discover an authentic taste of Japan that goes beyond the ordinary. Our handcrafted sweets are the perfect gift for loved ones back home, or a special treat for yourself.
Why Choose Our "Okome" Sweets?
- Naturally Gluten-Free, Genuinely Delicious Made entirely with Japanese rice flour, our sweets are 100% gluten-free — not as a compromise, but as a natural expression of the ingredient. Suitable for those with celiac disease, gluten intolerance, or anyone who simply appreciates fine pastry made with intention.
- A Unique Japanese Tradition While most pastries use wheat, we use 100% premium Japanese rice flour. This creates a wonderfully light, moist, and delicate texture ("mochi-mochi" "saku-saku" "fuwa-fuwa" feeling) that is uniquely Japanese.
- Handcrafted with Conscience Every piece is made by hand in our atelier. We are committed to practices that honor both people and nature — from ethically sourced ingredients, including eggs from animal welfare-certified farms, to packaging designed with the environment in mind.

Two Forms, One Spirit.
Two sweets born from the same premium Japanese rice flour, yet each with its own distinct character.
