Kaido★House Honda NSX Kaido Test Car Spec V1

Some models celebrate history. Others celebrate creativity. Every once in a while, a model manages to do both.

Our Model of the Month for May 2026 is the spectacular Kaido★House Honda NSX Kaido Test Car Spec V1, a release that perfectly combines one of Japan's greatest sports cars with one of the most recognizable custom diecast brands in the world.

The Honda NSX – A Japanese Icon

When Honda introduced the NSX in 1990, the company had one ambitious goal: build a supercar that could rival Europe's finest while remaining reliable enough to drive every day.

Developed with input from Formula One legend Ayrton Senna, the NSX became an instant benchmark for handling, balance, and driver confidence. Its lightweight aluminum construction, naturally aspirated V6, and mid-engine layout delivered an experience unlike anything else on the road.

More than thirty years later, the NA1 NSX is still regarded as one of the greatest Japanese sports cars ever built and remains one of the most beloved icons of JDM culture.

Kaido★House – Where Diecast Meets Custom Car Culture

Founded by legendary Hot Wheels designer Jun Imai, Kaido★House was created to celebrate Japan's vibrant tuning scene.

Rather than producing factory-stock vehicles, Kaido★House imagines what these legendary cars could become when builders are given complete creative freedom. Every release features aggressive styling, premium detailing, and the unmistakable Kaido★House design language.

The Test Car series offers collectors a rare glimpse behind the scenes. Inspired by prototype and development vehicles, these models represent the cars before production—when engineers, designers, and test drivers fine-tune every detail. The result is a livery that feels authentic, purposeful, and unlike anything else on the market.

The Model: Honda NSX Kaido Test Car Spec V1

The first thing that catches your eye is the understated grey bodywork, allowing every detail of the build to stand out.

Highlights include:

• Aggressive wide-body conversion inspired by Japanese street and circuit builds.

• Functional opening rear hatch, revealing a beautifully detailed mid-mounted engine.

• Classic pop-up headlights, faithfully recreated.

• Carbon fiber detailing on the wheel covers.
• Bright blue deep-dish wheels, creating a striking contrast against the grey paintwork.

• Red accents throughout the exterior, adding a motorsport-inspired touch.
• Authentic GReddy and ADVAN sponsor graphics.
• Signature "100% Kaido House" lettering above the side windows.

• A beautifully detailed interior that complements the premium exterior finish.

At the rear, a full-width taillight bar gives the NSX a modern, purposeful appearance, while the "Prototype" graphics reinforce the development-car theme that makes this release so unique.

Every element feels intentional, creating a model that is bold without becoming overcomplicated.
