Ultimate Guide for Overseas JDM Fans: Watching Tuning Car Events at Okayama International Circuit
Are you planning to explore Japan’s tuning car culture in the Kansai region?
While Fuji Speedway and Tsukuba Circuit often get the spotlight, Okayama International Circuit (OIC) is a hidden gem that offers a more local and authentic experience for JDM enthusiasts. From grassroots tuning festivals to winter time attack sessions, this track is where regional tuners and serious enthusiasts gather.
In this guide, we’ll share what makes Okayama International Circuit special, which tuning events to look out for, the best season to visit, and how to plan your trip with nearby JDM hotspots in Kansai.
What is Okayama International Circuit?
Located in Mimasaka, Okayama Prefecture, this 3.7 km technical circuit is famous for its flowing medium-speed corners and challenging layout.
It’s a track that rewards precise car setup and skilled driving, making it popular among tuners and time attack teams in western Japan.
Its location between Osaka, Kobe, and Okayama Airport makes it a great stop for Kansai-based JDM tours.
Popular Tuning Car Events at OIC
Okayama hosts a variety of events throughout the year. While it’s not as internationally famous as Fuji or Tsukuba, that’s exactly what makes it so appealing—it’s more intimate, less crowded, and deeply connected to local tuning culture.
Local Tuning Festivals
Several times a year, local tuning shops gather for demo runs, shop booths, and casual time attack battles. Perfect for fans who enjoy a relaxed, authentic vibe.
Supercar & Tuning Mix Events
Occasionally, you’ll find events where domestic tuning cars share the track with imported supercars, creating a unique mix of styles and cultures.
Winter Test Days
Just like at Fuji and Tsukuba, winter (January–February) is the prime season for time attack and testing. Many shops bring out their demo cars for private sessions or low-key open runs.
Best Season to Visit
The high season for tuning cars is winter (January–February).
Cooler air temperatures mean better engine performance and more stable lap times, so many shops schedule their record attempts during this period.
From spring to summer, tuning-focused events become rare, with endurance races and manufacturer-backed series dominating the calendar. In autumn, small tuning meets and local festivals return.
How to Get There
Public transportation alone is not very convenient. The nearest station (Hayashino Station) is still quite far, and buses are infrequent.
The most practical way is to rent a car or book a private transfer, especially if you’re coming from Osaka, Kobe, or Okayama city (around 2–3 hours by car).
Kansai JDM Spots to Combine with Your Trip
Visiting Okayama International Circuit is a great opportunity to explore Kansai’s unique JDM culture. Consider adding these stops:
