The long-selling product “Mille-Feuille (10 pieces, ¥1,296 including tax)” by Japanese confectionery maker Mary Chocolate has won the Grand Prix, the highest honor, at the Japan Food Selection, a prestigious award judged by over 23,000 food experts across Japan. To commemorate the award, the company opened the mille-feuille production process to the media for the first time.
Here are 6 more images, including the production process of Mary Chocolate’s mille-feuille.
Mary Chocolate is a long-established Japanese confectionery manufacturer founded in Aoyama, Tokyo in 1950. Specializing in Western-style sweets—mainly gift chocolates—the company played a pivotal role in establishing Valentine’s Day culture in Japan by being the first to promote the idea of women giving chocolates to men on the occasion.

The Funabashi factory we visited this time is the only Mary Chocolate facility dedicated to producing baked sweets. It manufactures items such as mille-feuille and cookies.

Mary Chocolate’s mille-feuille features layers of crispy puff pastry and cream, finished with a double coating of chocolate. The brand offers 21 varieties and produces 37.24 million pieces annually.

The production process takes three days and involves baking, cooling, cutting, and finally coating with chocolate. The sight of a massive flow of mille-feuille being covered in chocolate is truly impressive. After that, the products undergo thorough inspections for foreign objects using metal detectors and other equipment. The final step is packaging, completing the process.
The manufacturer describes the mille-feuille’s strength as “a rich, distinct chocolate flavor.” They explain that the pastry is made with a total of 144 layers and has “a light, delicate texture that melts smoothly without interfering with the chocolate’s melt-in-your-mouth quality.”
