Alonso and Honda will re-unite in F1 from 2026 now that the two-time world champion has signed a contract extension with Aston Martin.
It marks a renewal of a partnership that triggered a great deal of frustration when they were at McLaren together from 2015 to 2017, as Honda's engines proved to be uncompetitive.
The partnership reached a public nadir at the 2015 Japanese Grand Prix when Alonso famously came on team radio and labelled the Honda a "GP2 engine".
The troubled relationship had prompted some doubts about whether Alonso and Honda could work together again, but that debate has now been put to bed with their future in F1 sorted.
Honda Racing Corporation president Koji Watanabe has now explained that his company's relationship with Alonso has moved on greatly.
Speaking about working with Alonso again following the harsh comments he made in the McLaren era, Watanabe said: "When I worked with him from 2015 to 2017, it was a very difficult situation for both Honda and the team.
"It was a particularly frustrating period in our history, and there were times when our relationship was strained.
"But, I think we have become stronger because we overcame that frustration. Alonso has also been very active since then.
"I'm glad that we can overcome that painful experience together and fight together for victory once again. I hope that we can aim for the championship together and win together."
