Ochiai employs an integrated production system that enables everything to be performed and resolved in-house, from hearings with customers to product design, prototype and die manufacture, mass production, packaging and follow-ups after delivery. By engaging in practical product design from the very start that anticipates mass production, we are able to recreate a testing environment that is almost identical to actual mass production sites. The designers create and test prototypes themselves, which enables them to accurately reflect the intent of the design, as well as quickly responding to feedback from testing results. This has resulted in reduced development times and increased precision in regards to required specifications and performance.
