Midori Seibi Center

Midori Seibi Center is a Yokohama-based specialist garage offering vehicle inspections (shaken), high-difficulty mechanical repairs, tuning, and diagnostic services such as Dynapack chassis dynamometer checks and 3D four-wheel alignment.

Known in enthusiast circles for GT‑R and performance parts and services, the company lists a new factory opening in 2026; older directory listings still show the Kawawachō address. Contact phone on the official site: 045-933-1101.

A hands-on performance workshop focused on repairs, tuning and testing rather than a retail showroom. Expect technical work on engines, ECUs, transmissions, suspensions and bespoke GT‑R parts.

Look out for:

• Vehicle inspections (shaken) and routine maintenance.

• Dynapack chassis dynamometer power and tuning checks.

• 3D four-wheel alignment and high-difficulty mechanical repairs.

• Manufacturer/enthusiast parts and GT‑R-specific tuning experience.

Best way to experience it: Call ahead to confirm the current workshop location (the official site lists a new factory opening in 2026), ask about required paperwork for inspections, and schedule a slot for dyno or alignment work to avoid wait times.

• Official phone: 045-933-1101 (listed on the company site).

• Business hours listed as 10:00–18:30; closed Mondays, 1st & 3rd Tuesdays and holidays.

• Official site announces a new factory address for 2026; older listings may show Kawawachō 140.

• Workshop specialises in performance tuning—call ahead rather than dropping in.
