Tomoki Iwata’s Redemption Arc: From Celtic Afterthought to Birmingham City Star
Tomoki Iwata’s rise at Birmingham City this season has been nothing short of remarkable. It’s a story that combines ambition, timing, personal growth, and the ever-complicated nature of footballing careers. In the space of less than a year, Iwata has gone from being a peripheral figure at Celtic—a club steeped in tradition and competing regularly at the highest levels of the European game—to becoming a central figure in Birmingham City’s League One title-winning campaign, earning a nomination for League One Player of the Season in the process.
That kind of turnaround doesn’t happen by accident. It stems from a combination of hard work, tactical fit, and a desire to prove yourself—something Iwata has done consistently since his move to England’s second city.
The Move That Raised Eyebrows
When news broke that Tomoki Iwata was leaving Celtic in the summer of 2024 to join Birmingham City, many fans were puzzled. Why would a player willingly walk away from a club that competes in the UEFA Champions League, regularly lifts domestic trophies, and boasts one of the most intense footballing cultures in Europe?
After all, this wasn’t just any club—this was Celtic. A club with global recognition, a passionate support base that fills Paradise every week, and a demanding environment where expectations are sky-high. For some, it appeared as though Iwata was settling or perhaps even giving up on playing at the highest level.
But scratch beneath the surface, and the move made a lot more sense.
Iwata’s time at Celtic never quite took off. Signed from Yokohama F. Marinos in 2023, during the tail-end of Ange Postecoglou’s time in charge, the Japanese midfielder came with plenty of promise. He was known for his discipline, intelligence, and ability to shield the backline while keeping things ticking in midfield. However, at Celtic, breaking into the midfield setup was always going to be an uphill battle.
At the heart of that midfield stood Callum McGregor, club captain, and one of the most consistent performers in the Scottish Premiership. Alongside him, Reo Hatate was quickly emerging as a generational talent. And as the 2024/25 season approached, Celtic further bolstered their midfield ranks with the arrival of Arne Engels—now widely regarded as one of the best pieces of business the club has done in years—and Luke McCowan, whose dynamic style brought a new edge to Celtic’s midfield.
Faced with limited playing time and little sign of that changing, Iwata made a brave call—one that required humility, confidence, and ambition. He chose to leave the Champions League lights behind for a project that offered something else: an opportunity to start every week, to lead, and to be a fundamental part of something new.
Birmingham’s Ambition: A Project with Muscle
Birmingham City, fresh off relegation to League One, were not content with mid-table mediocrity. Backed by serious investment and a clear vision, the club spent aggressively in the transfer market to ensure a swift return to the Championship. The headline deal was the club-record £15 million spent on Fulham striker Jay Stansfield—an eye-watering amount for a third-tier side and even more remarkable when you consider that it’s higher than Celtic’s club-record signing of Arne Engels.
But the money wasn’t just thrown around for the sake of it. The recruitment was strategic, and Iwata was a key piece of that puzzle. He wasn’t brought in to sit on the bench or fill a squad role. He was targeted to be a leader in midfield, someone to dictate play, break up opposition attacks, and provide a calm, composed presence in high-pressure matches.
And that’s exactly what he delivered.
Thriving in England: A Midfield General
From his first few appearances, it was clear that Iwata had found a system and a league that suited his style. League One is known for its physicality, relentless pace, and unforgiving schedule. It’s a league where consistency and mental toughness matter just as much as technical ability. And Iwata has thrived.
Playing at the base of Birmingham’s midfield, he’s helped them dominate possession, control games, and frustrate opponents with his reading of the game and disciplined approach. He’s also shown a different side to his game—a more offensive one—chipping in with goals, including a stunning strike in the FA Cup that turned heads and underlined just how far his confidence had grown.
What makes his rise even more impressive is that Birmingham haven’t just gained promotion—they’ve done so with games to spare, steamrolling much of the competition along the way. That dominance is partly down to their financial firepower, yes, but also down to players like Iwata stepping up and delivering week after week.
Recognition: League One Player of the Season Nomination
The culmination of his performances has been his nomination for the League One Player of the Season—a significant recognition for a player many had written off. He finds himself on a three-man shortlist alongside Wycombe’s top scorer Richard Kone and Barnsley’s influential playmaker Davis Keillor-Dunn.
It’s a shortlist that reflects the variety of impact players can have—goals, creativity, leadership—and Iwata’s inclusion proves that he’s not just riding the coattails of a strong team, but genuinely shaping games from midfield.
Celtic Fans React: Respect or Resentment?
Back in Glasgow, Celtic fans have had mixed reactions to Iwata’s success. On one hand, many acknowledge that he was never going to get regular minutes in a midfield already stacked with talent. His departure allowed Celtic to reshuffle, bring in Engels and McCowan, and continue building towards domestic dominance and improved European campaigns.
On the other hand, there are more dismissive voices. Some supporters, like @socbhoy on social media, have taken his success as proof of the gulf in quality between Scottish football and England’s lower leagues. “Shows the standard of the English Championship, he was very average for Celtic,” one post read. Others have suggested he’s simply found his level, hinting that while he might shine in League One, he was never good enough for the rigours of top-level football, especially the Champions League.
But such takes may overlook the nuances of football careers. Players can thrive in different systems, under different managers, and in leagues that play to their strengths. Iwata’s composure, positioning, and tactical intelligence might not have dazzled in a Celtic team built around high intensity and fluid attacking football, but in Birmingham’s structured, possession-based setup, he’s flourishing.
What the Future Holds
Now that Birmingham have sealed promotion to the Championship, the next chapter of Iwata’s journey begins. Can he replicate his form in a more competitive division? Can he continue to evolve and perhaps even earn a return to the top flight down the line?
There’s every reason to believe he can. His work ethic, adaptability, and professionalism have been praised by teammates and coaching staff alike. And if his upward trajectory continues, he may very well find himself being talked about not just as a redemption story, but as a late bloomer whose best football is still ahead of him.
Final Thoughts
Tomoki Iwata’s journey is a refreshing reminder that football isn’t linear. Not every player fits every club, and not every dip in form is the end of the road. Sometimes, a step down in level can be the springboard for a leap forward in career. At 28, Iwata has reignited his career and found a new home where he’s appreciated, trusted, and performing at the highest level of his ability.
While his time at Celtic might not have gone as planned, his story should be celebrated—not just for what he’s achieved, but for the courage it took to walk away from the comfort of a big club and chase something more meaningful: purpose, pride, and playing time.
And in football, that’s what truly matters.
