Shigehara Manufacturing Co.,Ltd.

We manufacture high-precision in-vehicle parts in small lots with short turnarounds

Our company possesses a wide range of processing equipment for part production, and develops self-designed transmissions and speed reducers. We have supplied engine gears for the Toyota Lexus, while supplying racing car parts for MotoGP and Superbike events. This know-how helps us make high-precision small-lot prototypes in a short time. We have been engaged in EV development by working with many universities and companies. One of the demonstration vehicles, the EV86, is a first prize-winner with the six-speed Dog-type sequential transmission that our company developed for EVs. 


Other presentation

[Company Strengths]
Our company possesses technology to manufacture small-lot prototype parts in a short time with the high precision required for actual production. This is done by making use of the Monozukuri craftsmanship know-how we gained from supplying engine parts and transmission parts for racing cars. We have a wide range of processing equipment necessary for manufacturing engines and transmission parts to provide responsible support from materials to the finished product phase. Our strengths are high-precision gear cutting, 3D model machining, and inspection and measuring technologies. We also develop self-designed transmissions and speed reducers. 

[Business Description] 
Our company manufactures high-precision small-lot parts and even prototype auto parts as well as racing car parts in a short time. We design and plan the entire manufacturing process except for special processes such as heat treatment. 

Metal working industry

[Product and Technology Strengths] 
Our company excels at high-precision parts. We have supplied engine gears for Toyota the Lexus LFA as well as racing car engines, gears, and clutch parts for events such as MotoGP and Superbike. We have established a broad network of manufacturers who can offer machining of difficult-to-cut materials and special surface treatment. We can reduce lead time by offering our know-how on replacing processing with special jigs, tools, and molds and dies. In some cases this can reduce part production from two months to two weeks. We have a track record of 400 items per month and 5,000 items per year in prototype part production. This has allowed us to develop a unique know-how that helps us propose suitable manufacturing methods for the necessary parts. 

[Representative’s Message]
We will demonstrate our development capabilities to the development departments of automobile and household appliance manufacturers to further expand our customer base. This will be done by participating in JEVRA (Japan Electric Vehicle Race Association) race events as well as various events and consortiums. We will also consider selling Toyota 86 and other transmissions for high-torque competitions in response to requests from overseas customers.

[Company Structure for Market Cultivation and Overseas Expansion] 
Our company already has a suitable company structure for faithfully responding to development and procurement departments of major companies because of our past experience of working with many of them. 

[Market Share and Rank] 
The total of domestic Japanese unit sales of racing-car and circuit-use mission gear is unclear. However, we assume that our company has the largest share at 70% or more, and ranks No. 1 in the market. Almost 100% of the speed reducers in racing EVs and demonstration EVs and EV buses are designed and manufactured in our company.
