As usual, the passenger drift rides, where showgoers got to travel sideways with professional drifters, were a massive hit, as were the new-for-2016 highlights of monster truck rides and helicopter flights above the Northamptonshire circuit.
Almost 1,000 of the finest cars on the scene were exhibited as part of the event's club and individual displays, including a special 40 car line-up from the Mazda MX-5 Owners Club and a special 'Best of Boxer' display, celebrating 50 years of Subaru's rally-winning flat-four engine.
The coveted best club stand award went to Fitment Junkies for their diverse line-up, while the Wheel Whores Best Wheels award went to Karl Green for his Honda Civic Type-R.
The overall shown and shine winner was Alan Moss, for his 2010 Subaru WRX STi.
Event manager Katherine Chappell said: "This year's Japfest Rock was really well attended, proving just how important the Japfest series of events are in the scene calendar. Having seen the original Japfest grow this year, a strong turnout at Rockingham proves just how much of a thriving Japanese car scene there is in the UK."
And there's good news for fans of Japfest, with a third opportunity to celebrate the cars and culture of the Japanese cruising scene set to take place on September 11 at the Hop Farm, Paddock Wood, Kent. The family-friendly venue offers much more than just a car show, with plenty of attractions for the entire family.
The all-new Japfest Motorsport Heroes event will be a static show with a focus on the cars that really brought Japanese brands to prominence in the UK through their motorsport antics.
Among the thrills for visitors on the day will be a once-in-a-lifetime opportunity to experience the raw power and excitement of a Group N rally car from the passenger seat - The London Rally School will have both its Subaru Impreza and Mitsubishi Evo there, with rides available for £15 a head.
