Interview Comments by CEO, Yasuhiro Masuda

Why were you inspired to create Rakusashi-kun( Automatic Skewering Machine)?

I always think that we want to, or have to, contribute to people, society by our more than 50 years cultivated professional skill-sets of metal processing with our talented craftsmen.

About 6 years ago, some of my friends owning Yakitori Restaurants, asked me the exact same thing, ""Can you create an automatic skewing machine enabling us to minimize the burden of our workers/chefs, with increasing productivity?""

I was wondering, but I wanted to help people, so decided to start up developing. It was seriously difficult challenge. But I paved the following basic concept of this automatic skewing machine:

1st = Easy to use by everyone, regardless of experiences, 2nd = Reliable Safety, 3rd = Drastic Improvements of Productivity, and 4th = Reasonable Prices.

It took more than 1.5 years process of experiment & development, we finally could create this “Rakusashi-kun”.

After releasing this machine, we have been selling more than 550 units in past 4 years, even though we don't do any promotion. But through words of mouth, from people to people, Gradually, but surely awareness of our "Rakusashi-kun" has been penetrated into Japanese market.

I think, as one of major reason why this "Rakusashi-kun" has been evaluated in such short periods, It is that we can realize drastic improvements for their productivities, by our reliable quality upon our professional skills, in addition to our enthusiastic motivation for contributing to society.

You have vison of your business?

“Kusisasi" in Japanese means “”Skewering””, but having another meaning “”Bonding Together!””.

Therefore, we want to be the sort of Diplomatic Ambassador and Hub, not only selling this “Rakusashi-kun”, but expanding the awareness of Kawasaki, other collaborative partners, and enlarging our community together!
