Yashio Factory (ヤシオファクトリー)

Yashio Factory (ヤシオファクトリー) is a Sōka-based tuning and parts shop operated by Hot Staff Co., Ltd., focused on development and sale of performance parts—especially for Nissan Silvia models. The business combines a retail shop, parts development, maintenance and a branded online store.

Visitors can browse Yashio Factory–branded engine, exhaust and suspension parts, see display/tuned vehicles, and book the YASHIO CAR RENTAL program to drive tuned NA models under the company's rental terms. Staff contact and business hours are published on the official site.

You’ll see Yashio Factory’s in-house parts and tuned cars, and can buy parts or arrange a rental drive.

What to expect on site:

• Showroom/retail area with branded engine, exhaust and suspension parts.
• Display of tuned vehicles (not a formal museum) and merchandise like apparel.
• Workshop/maintenance area where in‑house development and tuning work is performed.
• Option to book the YASHIO CAR RENTAL for a drive in a tuned NA vehicle (rental requires deposit and conditions).

• Business hours typically 10:00–20:00; regularly closed Mondays.
• Official address and phone listed on site: Saitama (Sōka) and TEL 048-948-7140.
• YASHIO CAR RENTAL exists but requires a deposit and adherence to rental terms.
• Not a public motorsport venue—expect a working workshop environment and retail operations.
