Why insist on using iron (steel plate)?
Why is iron (steel plate) better for frying pans?
To cook or sauté food deliciously, a high temperature of approximately 170-180°C is necessary. Iron can withstand even higher temperatures, but its most distinctive feature is its heat retention and heat dissipation properties.
In other words, it possesses the property of retaining a large amount of heat, while simultaneously having optimal heat dissipation characteristics for many ingredients. This characteristic allows for high-temperature, short-time cooking, enabling you to cook without losing flavor.
And the greatest advantage of iron is that "the more you use it, the more the oil seasons it and the better it performs." Unlike Teflon, which deteriorates in a few months to a few years, if properly cared for, it can be used for decades to a century, passed down from parent to child, and from child to grandchild. It's not a "tool that you buy and throw away one after another," but rather a "tool that you can cherish and nurture to become even better."
Riverlight is a Japanese cookware manufacturer founded in 1976 and based in Shiroi City, Chiba Prefecture. Since its founding, the company has focused on cast iron frying pans, continuing to create durable, functional cookware that becomes more cherished the more it is used.
The main features of the representative "KIWAME" series are:The iron surface has been subjected to a special heat treatment.。
The "nitriding + oxidation treatment" creates a nitrided iron layer and an iron oxide layer on the surface, resulting in a frying pan that is more rust-resistant and durable than typical iron frying pans. It is also easier to handle than conventional iron frying pans, as it does not require seasoning after purchase and only needs to be washed and wiped after use.
And what distinguishes Riverlight frying pans is,Wooden handleis.
The "Kiwami" series features handles made from natural wood. By combining this material with the iron frying pan body, it has a warm feel when held and a design that blends easily into a home kitchen.
Furthermore, this handleReplaceable structureThis is how it works. Even if the wooden handle gets damaged after prolonged use, you can continue using it by replacing the handle instead of having to buy a whole new unit.
There are 12 different models representing each birth month, with a wide variety of woods and lacquer finishes to choose from.
Not just the frying pan itself,Designed with "long-term use" in mind, including the handle.This is one of the unique charms of Riverlight.
Furthermore, Riverlight uses cold-rolled steel sheets for the body of its frying pans.SPCC material manufactured by Nippon Steel CorporationIt is officially stated that they use [the same technology/material]. The product itself is also labeled "Made in JAPAN".
In addition to standard frying pans, they offer a range of products tailored to different cooking needs, including stir-fry pans, omelet pans, crepe pans, and thick-plate frying pans. Some of their thick-plate frying pans even use 3.2mm thick steel plates.
Riverlight has changed the perception that "iron is difficult to work with because it rusts" through its special heat treatment technology.
This Japanese frying pan manufacturer takes the best qualities of traditional iron as a material and evolves it into a tool that is easy to use in modern households.

While retaining the best qualities of iron, this iron frying pan is now rust-resistant. In 2006, we developed and began selling the nitrided iron "Kiwami" frying pan, the predecessor to Kiwami JAPAN. Utilizing our years of experience and knowledge in nitrided iron frying pans, we have further improved quality. Through metal heat treatment technology, "nitriding + oxidation," this iron frying pan is significantly more rust-resistant and robust than typical iron frying pans. Rust-resistant means... ① No pre-seasoning required after purchase: Simply season with oil and start using immediately. ② After use, just wash and wipe: No pre-seasoning or oiling after washing is necessary. The deliciousness of "iron": An overwhelmingly crisp texture. Iron can quickly transfer heat to ingredients, allowing you to create stir-fries with an authentic texture. Crispy and fragrant sear. You can achieve a fragrant aroma and a crispy sear on the surface. Even simple dishes will have a higher-quality finish. Delicious and healthy meals are paramount. By using iron, you can take in iron while pursuing even greater deliciousness. Cooking tools that you use for decades. These are cooking tools that can be used for decades, developing alongside the user's culinary skills. Adding iron to ingredients for healthy meals. Iron, which is often deficient even with conscious effort, can be supplemented by using an iron frying pan. Unchanging design. A timeless design that has remained unchanged for half a century. The basic design has remained the same since the company's founding, and even the original frying pans can be replaced with current replacement parts. For nearly half a century since its founding, the techniques have been passed down. Each piece is manufactured by hand by skilled craftsmen. The same manufacturing methods since the company's founding, combined with innovative nitriding technology. The current "Kiwami" is the result of years of tireless quality improvement. Our approach to manufacturing is entirely focused on creating delicious and healthy food. Cooking is a natural science. Just as it's common knowledge that "water boils at 100°C," there's also a specific temperature for delicious cooking. Caramelization of sugar (170°C), and a similar reaction, the Maillard reaction (180°C) that causes browning when sautéing onions, cannot be altered by the cook's arbitrary heat settings. Cooking at the correct temperature allows us to enjoy the life we consume to the fullest, which is not only a sign of respect for that life but also contributes to our health. Since its founding in 1976, Riverlight has consistently manufactured only iron frying pans in its own factory, based on the belief that if you seek the essence of frying pan cooking, it must be iron. Rather than pursuing products that sell, we have cherished our company's beliefs and have continued to this day. We will continue to manufacture today while cherishing the unchanging beliefs and designs since our founding.
