When you were a child, you might have thought, "I hate an injection because it hurts." On the day before getting a vaccination shot, every child wished there were a painless needle.In fact, this childhood dream is about to come true with his company.But you might be still skeptic. In theory, if a needle were as thin and smooth as the mosquito's proboscis, an injection should be painless for most people. It is also strong enough not to snap or bend when it is pushed into the skin, while it is as fine as a hair. A representative of Terumo Corporation in charge of developing a painless needle brought the drawings to him. It took one and a half years to develop the needle.

Okano wasted material worth more than \1 million. With his labor expenses included, the total cost should exceed 100 million yen. However, this would be a big business if the commercialization succeeds. A needle is a consumable article. If it becomes available across the world, the profits would be enormous. Best of all, even children would be able to receive an injection with a smile on their face. This is the most valuable aspect of this invention.
