Feelings for i-OTA

 We would like to contribute to the further revitalization of the manufacturing industry by further utilizing the "nakama mawashi" (inter-company collaboration) that we have cultivated through the Shitamachi Bobsleigh Project and other projects, enabling us to acquire projects that we cannot handle on our own and to take on new, untapped businesses, thereby contributing, however slightly, to the further revitalization of the manufacturing industry.

I-OTA will continue to grow into a group of companies that have accumulated skills and knowledge, and that can do anything if you ask us, and that we can understand anything if you ask us.

Case study

Plastics are used as insulating and heat-insulating materials in various devices, and we have accumulated experience and know-how by taking on the challenge of cutting FRP (Fiber Reinforced Plastics), one of the most difficult materials to cut, from early on.
We also specialize in processing plastic in sheet and film form, and can process even sheets as thin as 0.1 mm in thickness. We can process various sizes, from thin to thick, and from palm-sized to large format products such as 1000mm x 1000mm.


We want to be a bridge connecting people to people and people to things.

The world we live in is filled with many things. For example, plastic parts are used in everything from the computer you are looking at on this screen, to cell phones, cars, trains, airplanes, and even rockets. We can convey our feelings to our loved ones through phone calls and e-mails, or we can meet the people we want to see in person through pictures and rides that bring smiles and tears to our faces. The parts we make may be small and out of sight, but they are helping to connect people to each other through objects. I have come to feel that way someday.
We will continue to think about "what we can do for our customers" and do our best to be of service to you.
