As Japan grapples with a shrinking workforce, NAKANISHI’s vision for automated, sustainable kitchen technologies guarantees that it preserves wholesome, nourishing food for generations to come.

Food has long been the backbone of human socialization. A lunch break is more than just a time to eat; during our school days, it's where we solidify the bonds that can last a lifetime. It’s a moment of nourishment, both physically and spiritually, shared by millions of children around the world. Here is where habits are formed, tastes are acquired, and a sense of care is passed between the community and the child.
In Japan, behind the seemingly mundane, is an intricate choreography of hygiene, precision and warmth. For decades, NAKANISHI MFG has been one of the unseen conductors guiding that choreography with its systems and technologies, which allow food to be prepared safely, beautifully, and at scale. The company’s work begins long before the rice is washed and continues long after the final tray is served.
For over 80 years, the company has played a foundational role in food preparation in Japan, supporting both local kitchens and global brands to the highest standards of safety, hygiene, and quality. The company provides integrated kitchen systems that span architectural facility planning, equipment manufacturing, installation, and maintenance, ensuring reliable and consistent food production environments. President Kazuma Nakanishi says that Japan’s strength lies in its holistic approach, which is responsible for the country's reputation for safe, hygienic, and consistently high-quality food.
Today, the company is advancing a new mission: developing kitchens in a future challenged by labor shortages, rising quality expectations and a rising demand for sustainability. “As labor shortages intensify, automation supported by robotics and AI is not an option but a necessity,” the president says.
Japan’s renowned school lunch system illustrates the challenges ahead perfectly, with hygiene and operational standards among the world’s highest. “It is not just about rules—it is an entire system of design, equipment, workflow, and even maintenance,” President Nakanishi says.
Energy-Save Rice Cooking system
As Japan faces severe labor shortages, NAKANISHI has identified automation as essential to sustaining high-quality kitchens. “Imagine a system where ingredients are delivered, processed, cooked, and served entirely without human intervention—robots handling every stage, with AI ensuring consistency and quality,” he says.
However, to get there, the company is rolling out practical automation systems that can be adopted by schools, central kitchens and factories that will serve as stepping stones for the kitchens of the future.
One of the company’s flagship automation-forward technologies is the SV Roaster, a continuous conveyor-type oven that uses “SuperHeated Steam” to cook food evenly and efficiently. The roaster creates an ultra-low-oxygen environment, reducing oxygen levels to below 0.1 percent, creating an atmosphere that prevents oxidation and preserves freshness and flavor. With high heat transfer and shorter cooking time, the SV Roaster improves yields and offers scalability for kitchens while requiring less labor than traditional machinery.
For rice, Japan’s cultural foundation, NAKANISHI’s rice-cooking solutions solve the pressing challenges of cost, labor and sustainability. The company’s energy-saving continuous rice-cooking system reduces gas consumption by approximately 23 percent, supporting lower running costs and creating a cooler, safer working environment where heat and stress are minimized. Meanwhile, its water-saving continuous rice washer reduces water usage by up to 60 percent, lowering both utility expenses and the environmental load of wastewater treatment. The result is a system that honors the texture and character of properly prepared food while meeting the growing call for sustainability.
NAKANISHI will be exhibiting at Food and Hospitality Asia 2026 in Singapore and will be found at booth number 2D2-01 to showcase its food service and hospitality equipment.
NAKANISHI’s vision is to ensure that the next generation of Japanese school lunches maintains its high quality, while being safe and sustainable, in an environment with fewer hands to prepare them.
