Tomoki Iwata has won English League One with Birmingham City.
The midfielder joined the St Andrew's outfit from Celtic for just over £850,000 last summer [Transfermarkt].
Iwata spent a year and a half in Glasgow's east end. He won a treble in his first six months with Celtic and played his part in a double success last campaign.

In total, the 28-year-old played 42 times for the Parkhead outfit, scoring one goal and assisting three along the way.
He has thrived since joining Birmingham in England's third tier last summer. Iwata has been a standout for the club, netting seven times in 40 games up to this point.
Yesterday, despite not even playing, his team secured the title. Wrexham's goalless draw with Wigan meant Birmingham were mathematically out of reach at the summit, and can now call themselves champions.
They are managed by Brendan Rodgers' former assistant at both Celtic and Leicester City, Chris Davies.
Davies served as a coach under Ange Postecoglou, who brought Iwata to Parkhead, at Tottenham Hotspur before taking the reigns at Birmingham.
His side take on Peterborough United at Wembley this afternoon in the final of the EFL Trophy.
They now know they will be playing English Championship football next season despite having six league games left of the current campaign.
"I am delighted for him," said Postecoglou after Davies and Birmingham secured promotion earlier in the week.
"I really enjoyed working with Chris. He was only with me for a short time last year, but I really enjoyed working with him. He was a big part of what we built last year. It was ground zero in terms of building a whole football programme in a different direction and he was a big part of that.
"Your first job is pretty important when you’re trying to embark on a career as a senior manager, and he’s done brilliantly well, which is not surprising."
"I am sure there is more to come from him."
