Japan Car Events in May 2026: SUPER GT Golden Week at Fuji, MOONEYES Street Car Nationals, and TOYOFEST JAPAN
On This Page
May 2026 is one of the busiest months on the Japan car event calendar. Golden Week opens the month with the biggest SUPER GT weekend of the season at Fuji, and the rest of May stacks a free supercar festival in Saitama, the legendary MOONEYES Street Car Nationals in Odaiba, back-to-back Toyota gatherings at Fuji on the final weekend, and a long-running rotary meet in the mountains of Gunma.
Whether you are planning a trip around Golden Week or arriving later in the month, this is the full updated picture for May 2026.
Major May 2026 Events
AUTOBACS SUPER GT Round 2 2026 at Fuji Speedway (May 3–4)
Dates: May 3–4, 2026
Location: Fuji Speedway, Oyama, Shizuoka Prefecture
The Golden Week SUPER GT round at Fuji is one of the largest motorsport spectator events in Japan each season. GT500 and GT300 machines run over two days with open paddock access, dense manufacturer presence, and the full Fuji Speedway atmosphere. Expect large crowds on both days, especially Sunday.
Why it matters: This is the marquee early-season SUPER GT round and the easiest one for Tokyo-based visitors to reach. Golden Week timing means accommodation around the Fuji and Gotemba area books out quickly.
What to expect: Full grid GT500 and GT300 action, open paddock on certain sessions, manufacturer displays, and a race-day atmosphere that is difficult to replicate anywhere else in Japan in May.
Access note: Driving is recommended for Golden Week traffic planning. Public transport visitors usually transfer from Gotemba by taxi or event transport. Book accommodation in the area well in advance.

KYOJO CUP Rd.1 / Interproto Series Rd.1 / Fuji Champion Race Series Round 2 (May 9–10)
Dates: May 9–10, 2026
Location: Fuji Speedway, Oyama, Shizuoka Prefecture
A two-day mixed race program at Fuji combining the opening round of KYOJO CUP — Japan's all-women single-seater series — with Interproto Series Round 1 and the Fuji Champion Race Series Round 2. A dense schedule across both days with multiple competitive classes.
Why it matters: KYOJO CUP rounds are smaller and easier to watch at close range than SUPER GT, and the multi-class format gives you continuous on-track action throughout the weekend.
What to expect: Single-seater battles, varied car classes, and the Fuji paddock at a more relaxed scale than the Golden Week race.

Fuji Speedway Official Super Taikyu Test 2026 (May 14)
Date: May 14, 2026
Location: Fuji Speedway, Oyama, Shizuoka Prefecture
Time: 9:00 AM – 8:20 PM
An official pre-race Super Taikyu test day at Fuji Speedway ahead of the Fuji 24 Hours in June. Long test sessions across multiple car classes give you close trackside access with paddock-side atmosphere and none of the race-day crowds.
Why it matters: Test days at Fuji offer a more relaxed way to see the cars and teams without the full race weekend logistics. The extended 9:00 AM to 8:20 PM window means evening running as well.
What to expect: Super Taikyu machinery across multiple classes, paddock access, and a lighter crowd than a full race weekend.

TOKYO SUPERCAR DAY 2026 Saitama (May 17)
Date: May 17, 2026
Location: Daimon Kami-ike Chosetsuchi Hiroba (near Saitama Stadium 2002), Saitama
Time: 10:00 AM – 4:00 PM
A free outdoor supercar and sports car festival near Saitama Stadium 2002, featuring around 100 display cars — Ferrari, Lamborghini, McLaren, Porsche, Aston Martin, Lexus LFA, Dallara, and domestic classics — alongside racing car demonstration runs, a kids supercar classroom, and food truck stalls. No entry fee and no visitor parking at the venue.
Why it matters: This is one of the easiest large supercar gatherings to attend in the greater Tokyo area without a rental car or long journey. Rail access is direct and the event is free.
What to expect: A broad mix of supercars and sports cars in an open outdoor setting, demonstration runs, and enough variety to fill a half-day visit.
Access: Saitama Stadium 2002 is served by the Saitama Rapid Railway (Urawa Misono Station). There is no visitor parking — arrive by rail. The event is a short walk from the station.

38th MOONEYES Street Car Nationals 2026 (May 24)
Date: May 24, 2026
Location: Odaiba Aomi Parking, Koto-ku, Tokyo
Time: 9:00 AM – 3:00 PM
Japan's largest outdoor car show and swap meet, organized by MOONEYES. Over 1,000 custom USA, domestic, VW, and Euro cars gather in Odaiba alongside 100+ swap meet vendors, pinstripers, and American food stalls. Rain or shine. Entry ¥1,980; elementary school age and under free.
Why it matters: The Street Car Nationals is one of the most important dates on the Japan custom car calendar. The combination of the car show, swap meet, and community atmosphere is genuinely hard to replicate anywhere else in Japan.
What to expect: A full day of custom cars, open swap vendor stalls, live pinstriping, food, and a strong MOONEYES community presence.
Access: Aomi Station on the Rinkai Line is the closest stop. The Yurikamome line also connects via Tokyo Teleport Station. There is no visitor car parking at the venue — use nearby paid lots if driving, or take the train.

MINI CAR A GO GO!! 2026 with HOTWHEELS JAPAN CONVENTION (May 24)
Date: May 24, 2026
Location: Makuhari Messe International Exhibition Hall 5-6, Chiba
Time: 10:00 AM – 5:00 PM
A one-day miniature car hobby festival at Makuhari Messe featuring diecast community activities and the Hot Wheels Japan Convention. If you collect diecast or want to see the scale of the Japanese miniature car hobby community up close, this is the best annual opportunity.
Why it matters: The Hot Wheels Japan Convention is a separate dedicated event within MINI CAR A GO GO, making this the most concentrated diecast gathering of the year in Japan.
What to expect: Exhibitors, private collections, trading, exclusive releases, and a strong community atmosphere across the Makuhari Messe hall.
Access: Convenient from Tokyo by train to Kaihin-Makuhari Station and a short walk to the venue. Drivers should expect heavier parking demand during major hall events.

TOYOFEST JAPAN 2026 and GR SUMMIT 2026 (May 30)
Date: May 30, 2026
Location: Fuji Speedway P1 / P2, Oyama, Shizuoka Prefecture
Time: 9:00 AM – 3:30 PM
Two simultaneous Toyota gatherings across adjacent Fuji Speedway car parks on the same day. TOYOFEST JAPAN 2026 runs in P2 as a Toyota and Lexus custom car show featuring curated display entries, VIP showcase cars, and a strong street and tuning focus. Directly next to it in P1, GR SUMMIT 2026 brings together GR-brand vehicle owners in a dedicated all-GR gathering — entry by registration via the official LINE account only.
Why it matters: Having both events on the same day at the same venue makes this the best Toyota-focused day of the year for visitors who want variety in a single outing.
What to expect: Custom and tuned Toyota and Lexus builds at TOYOFEST, an owner-community atmosphere at GR SUMMIT, and the Fuji Speedway circuit complex as the backdrop.
Access: Driving is the practical option for most visitors. Train travelers typically route to Gotemba and continue by taxi. GR SUMMIT entry requires advance registration via the GR SUMMIT LINE account — check the official account for details before attending.

Why it matters: Rotary meetings at this scale are rare and this one has earned a strong following in the enthusiast community. The mountain setting adds to the atmosphere.
What to expect: A focused gathering of rotary-engine vehicles, a community-oriented atmosphere, and one of the more scenic meeting locations in the Kanto area.
Access: Best reached by car. From Tokyo, take the Kanetsu Expressway to the Shibukawa-Ikaho IC, then approximately 20 minutes up the mountain to Ikaho. Spectator parking is available at the venue.

Best two-day pick: SUPER GT Round 2 at Fuji (May 3–4) if you want marquee motorsport. Book Gotemba-area accommodation early — Golden Week fills fast.
Best end-of-month pick: TOYOFEST JAPAN + GR SUMMIT on May 30 if you want a Toyota-heavy day at Fuji, or the Haruna Rotary Meeting on the same day if rotary culture is your focus.

Verification note: Event operators can still adjust programs, lineups, and ticket conditions closer to each date. Recheck the source links before traveling.
