A Taste of Kolkata in Japan: The Japanese Couple Serving Bengali Cuisine in Fukuoka
When we think of Japanese food, images of sushi, ramen, and tempura instantly come to mind. But in a quiet corner of Kasuga, Fukuoka, there is a restaurant where the aroma of mustard fish curry, roasted moong dal, and Kolkata-style biryani fills the air. Welcome to the Indian Spice Factory, a unique culinary venture run by Japanese couple Koji and Sachiko Nakayama, who have dedicated themselves to serving authentic Bengali cuisine to the people of Japan.
From Tokyo to Kolkata – A Journey of Flavors
Koji’s love affair with Bengal began in 2013, when he first visited Kolkata to assist in setting up a Japanese restaurant. What started as a professional opportunity soon turned into a deeply personal transformation. The city’s flavors, warmth, and cultural richness left a lasting impression on him.
Though his time in Kolkata was not without challenges—including being deceived by a trusted acquaintance—Koji chose to remember the positive. For him, Bengal was not just about food, but about an emotional bond with its people and traditions. These experiences became the foundation of the dream he and his wife Sachiko would later build together in Japan.
Building a Home for Bengali Cuisine in Fukuoka
In 2018, the Nakayamas opened Indian Spice Factory, a restaurant that aimed to bring the true spirit of Bengal to Japan. Unlike the usual “curry houses” scattered across the country, their restaurant focused on authenticity and tradition.
The couple serves a wide range of Bengali dishes, including:
- Shorshe Maach – fish curry flavored with pungent mustard paste.
- Bhaja Muger Daal – roasted moong dal cooked to golden perfection.
- Bengali Thalis – complete traditional platters with rice, dal, vegetables, fish, and sweets.
- Kolkata-style Biryani – fragrant rice with meat, potatoes, and the signature subtle spices.
Meals are thoughtfully served on banana leaves and in earthenware, just as one would find in Kolkata households and restaurants. The Nakayamas even grow some ingredients themselves in Japan to ensure that the dishes remain faithful to their origins.
To complement the Bengali classics, the restaurant also features South Indian favorites such as murukku (crispy snack) and the ever-popular phirni, a rice-based dessert served in clay bowls.
Sachiko’s Transformation: From Spanish Chef to Saree-Clad Hostess
While Koji discovered his love for Bengali cuisine in Kolkata, his wife Sachiko was a trained chef in Spanish cuisine. But when the couple decided to open Indian Spice Factory, she embraced the Bengali way of life with open arms.
Not only did she master the intricate art of Bengali cooking, but she also immersed herself in the cultural experience—dressing in a saree every day as she greets customers and serves meals. For many Indian visitors in Japan, seeing Sachiko in a saree, serving authentic Bengali dishes, has been an emotional experience that reminds them of home.
The restaurant itself is decorated with Radha-Krishna idols, traditional musical instruments, and clay artifacts, creating an atmosphere that feels unmistakably Indian despite being thousands of kilometers away.
Viral Fame and Emotional Reactions
The restaurant gained international attention when travel influencer Sonam Midha shared a video showcasing the Nakayamas’ work. In the clip, viewers saw banana-leaf meals, Sachiko in a saree, and the couple’s dedication to presenting food exactly as it is in Bengal.
The video quickly went viral, with social media users praising the “unmatched love” the couple has for Indian culture. Many Indians living abroad commented that the restaurant reminded them of home, while some even admitted that their “hearts filled with love” and their “eyes turned misty” watching the couple’s devotion.
More Than Food: A Cultural Bridge
What makes the Indian Spice Factory special is not just its food—it is the emotional connection it creates. For the Nakayamas, this is not about running a business; it is about paying tribute to a culture that touched their lives. For their customers, it is about experiencing a piece of Bengal far away from Kolkata.
The couple’s story is a powerful reminder that food transcends boundaries. A Japanese couple can fall in love with Bengali traditions, recreate them with devotion, and in the process, become cultural ambassadors between India and Japan.
The Indian Spice Factory in Fukuoka is more than just a restaurant—it is a love letter to Kolkata. In every spoonful of mustard fish curry, in every banana-leaf thali, and in every saree-clad smile from Sachiko, there is a story of cross-cultural appreciation and heartfelt devotion.
For Bengalis living in Japan, stepping into the Indian Spice Factory feels like stepping back home. For Japanese diners, it’s an invitation to taste a rich, diverse cuisine that goes far beyond stereotypes of “Indian curry.”
Ultimately, Koji and Sachiko Nakayama show us that food is not only nourishment—it is also memory, connection, and love across borders.
