Infiniti Kuraza was a luxury SUV concept car that debuted at the 2005 North American International Auto Show in Detroit. Designed to explore the future of luxury vehicle interiors, it prioritized maximum interior space and passenger comfort over traditional utility.

It featured three rows of two individual seats arranged in an "amphitheater" layout so every passenger had a panoramic view through the large windows and three overhead glass panels.

The most distinctive feature was its six doors—three on each side—which included rear-hinged (suicide) doors for the third row to allow unhindered access.

The interior design blended modern technology with traditional Japanese elements, such as seatbacks inspired by kimonos and a vertically oriented center monitor serving as a modern interpretation of a kakejiku (hanging scroll).

The cabin utilized natural materials including beige leather, hand-crafted wood, and milled aluminum alloy.

Despite its focus on "hospitality" and luxury, the Kuraza's polarizing exterior design was widely criticized. In a Wall Street Journal survey at the time, 69% of respondents voted it the "ugliest concept car" at the show.

The vehicle was strictly a design study and never went into production, though it served as a platform for Infiniti to showcase its vision for future luxury interiors.
