Joao Paulo de Oliveira had to give up ByKolles Le Mans seat

The 2010 Formula Nippon champion and long-time Nissan GT500 driver revealed he tested the ByKolles ENSO CLM P1/01 last year and that plans were also made for him to be part of the team's line-up for the preceding FIA World Endurance Championship round at Spa.

But Japan's strict immigration rules prevented de Oliveira from taking up the seat, as leaving the country would have prevented him from re-entering and honouring his commitments with the Kondo Racing GT300 team this season.

Instead, former DTM champion Bruno Spengler was chosen to join ByKolles regulars Tom Dillmann and Oliver Webb for the French endurance classic on September 19-20.

"I tested the car last year at Brno alongside Tom Dillmann," de Oliveira told Motorsport.com. "It was fantastic, the team was very happy with me and excited. And we agreed that I was going to race with them this year at Spa and Le Mans.

"And then all this mess [happened], especially in Japan not being able to leave the country and come back. If I was able to come back to Japan, it wouldn’t be a problem. But if I left now I couldn’t race again in SUPER GT the rest of this year, so it’s a no-no.

"It's very unfortunate because it was my first real opportunity to race in Le Mans, which I’ve always wanted to do."

Asked if he would target a Le Mans debut in 2021, de Oliveira replied: "Yeah. I’ve always had a good relationship with the team, I know Colin [Kolles] from way back in the past because I drove for him in [German] Formula 3 in 2002.

"We will keep in touch and we’ll see how things go on into next year. It’s tough times; the pandemic means everything is restricted on budgets. I think once the dust settles, we’ll know a bit more. It’s very hard to make plans for next year right now."

Since leaving Nissan's GT500 stable at the end of 2018, de Oliveira has tried his hand in a number of categories outside of Japan, including the Intercontinental GT Challenge, the FIA World Touring Car Cup and the Nurburgring 24 Hours.

Asked if he could see his future racing internationally, the Brazilian said: "I want to have a good year and see what options I have for next year, but I definitely want to fight for a championship next year, be it here [in Japan] or in Europe.

"We’ll see. It’s hard to speculate without knowing the options that are on the table, but I’m working towards going higher, not staying where I am. That’s for sure."
