Message from the President
Nice to meet you, I'm Mayuko Nishihara, CEO of Behomaru Co., Ltd.
Before starting my own business, I worked as a salaried researcher at a large corporation for 15 years, developing materials, analyzing failures, and developing new businesses. During this time, I learned about the quality control systems, production technology systems, and strategies that are unique to large corporations, while also experiencing a variety of challenges, such as the struggles faced by operating companies when new businesses cannot be launched, climate change measures that are incompatible with existing businesses, and open innovation that is merely a formality. To overcome these challenges, I attended a university for working adults called the Graduate School of Business Design, where I learned about the thinking and methods for creating businesses from scratch and obtained a Master's in Business Design (MPD).
The conclusion I came to was that "zero-to-one businesses are easier to achieve in an agility and empowered environment like a startup."
When I took out the trash in the morning, I had a small thought: "I've produced a lot of trash this week. I hope this trash can be put to good use until the end." Or, I had a perfect idea: "Wouldn't it be interesting if we mixed CO2 absorbent material into resin?" I think it was because I was so mobile that I was able to realize it.
As someone who has been involved in various development projects for many years in an engineering position, I find it strange that environmental activities dismiss past science and technology, such as saying that plastic is evil or that it is a shame to fly. Science and technology are not omnipotent, but I believe that it is precisely because they are not omnipotent that climate change countermeasures that are a win-win for everyone, including the Earth, can be born with new ideas and enthusiasm.
"Every little bit counts." When each individual changes their behavior, social issues come closer to being truly resolved. We want to be a force behind that change.
