This week, a quartet from the Japanese side have arrived for 10 days of training with Bournemouth’s U21s and U18s.
This comes after the two clubs announced a partnership in October, that would see the pair exchange best practice in youth development and coaching.
The four players that have travelled to Bournemouth are Yuto Anzai and Rikuto Iida, who will train with the U21s at the Cherries academy, while Sungjun Yoon and Ko Sakai will be with the U18s.
Asked about the exchange and what benefit it brings to the club, Iraola said: “It's something that the club normally does.
“There are a lot of players coming here like trialists, they come for a period, for some friendlies, and I think it's something that is good for the club.
“I think it's good to have also the more connections you have; is the more access you can get to good players.
“And I don't know these players obviously, but I hope if they are not these ones, we can give chances also for players that we think they can help us in the future.”
