Indonesian motorsport team Toyota Gazoo Racing Indonesia (TGRI) has made history by winning the GT4 Japan Cup 2025 title. The team's triumph was led by the formidable duo of Indonesia's Haridarma Manoppo and Japan's Seita Nonaka, who dominated the season by claiming nearly all first-place podiums across eight races from June to September.

Haridarma Manoppo expressed his elation, calling the win the most significant achievement of his career. "This is truly extraordinary, and it's the pinnacle of my racing career," said Haridarma in a written statement received by the press on Tuesday, September 23, 2025, as quoted by antaranews.com. 

"Especially since we know that GT racing is filled with great drivers, this achievement is absolutely remarkable for me." he added.

Haridarma also credited his teammate, Seita Nonaka, for his crucial contributions to the team’s success. He explained that Nonaka's insights into the unique characteristics of each circuit and their respective racing lines were invaluable.

The 2025 title is the culmination of TGRI's steady progress since their debut in the GT World Challenge Asia 2023, where they finished second overall. The following year, they competed in the full 2024 GT4 Japan Cup season and secured a third-place finish. 

This year, the team's performance surged with Haridarma's full focus and the solid teamwork with Nonaka.

This victory not only marks the highest point in Haridarma's career but also reaffirms the commitment of PT Toyota Astra Motor and TCD Asia Pacific Indonesia to developing motorsports talent at a professional level.

The championship win firmly places Indonesia on the map of international motorsport competition.
