Continuously take on challenges and leap to tomorrow.

Thank you very much for visiting the Hirai website.
We were founded in 1967 as a specialized manufacturer of photo etching processing and have grown into the industry’s largest company in Japan and the world.

With the motto of short delivery, high quality, and high added value, we supply products from R&D to mass production for more than 1,000 customers in Japan and overseas. We are also proactively responding to increasingly stringent environmental regulations.　We will utilize our various internal process technologies (machining, surface treatment, and bonding technologies) based on photo etching to meet our customer’s requiring products.
Our target is that we are discussed by customers when they are troubled with processing. We will repeat an effort every day towards.
