When we faced to the situation that many people were attracted by Messtin cooker for the past few years, our development team was struggled with the feeling that "Why do all the people forget that we have better item in Japan, Sangaku Hango!" However, it is also the fact that normal Sangaku Hango is made for cooking 4 cups of rice, which is calculated for 6-8 people...too big to carry for trekking. The ideal size is a half of it and it is exact the same size with "Sento Hango" Japanese Self-Defense Forces uses. From this, our journey for Sangaku Hango started.
