4w1h
4w1h is a kitchen tool brand created by Tsubame-Sanjo Kitchen Laboratory, a group of metalworking manufacturers, brand producers, product designers, graphic designers, and copywriters who have been involved in manufacturing in Tsubame-Sanjo for many years. Based on the concept of "4w1h," which is "5w1h" minus "where (kitchen)," the brand re-edits existing kitchen tools from the viewpoint of why, when, who, what, and how, to create innovative products.
What is 4w1h's craftsmanship?
Continuous observation
In their product development, careful observation is made: usage scenarios of developing tools, specifications, design, and manufacturing techniques. They create products through careful and continuous observations and verifications from all angles.
Those processes are not performed by each professional individually. Professionals in each field gather to share all activities, including brand direction, product planning, development, sales, and communication. The manufacturing process is carried out through continuous dialogue and prototyping.
In order to realize their desire to continue to provide products that not only satisfy customers’ needs but also make them realize that “Yes, this is what I needed!” it is essential to ask questions from a variety of angles.
4w1h continues to discuss and verify even things seemingly not necessary to think that far.
The secret to creating unprecedented and groundbreaking products must lie in the teamwork that goes into it.
Brand's Signature Gear
Hot-Sand Solo
A signature product of the 4w1h series that allows you to make a hot sandwich with a single slice of bread. It was created from the realization that when people eat hot sandwiched, it is normally in the morning, and for many people, only one piece of bread is enough for breakfast. By placing the ingredients on top of the bread and wrapping the ingredients in the bread, it is possible to cook with only one piece of bread. This product, which is both a signature and a symbol of the brand, is numbered “001” in the product number.
