Iwasa, who is a former JBC and OPBF champion at Bantamweight, didn't indicate a specific date or target opponent for his comeback though it's great to hear that he is concentrating on his ring return and will hopefully take the experience of the Haskins fight to rebuild his own style, which appeared to be very predictable and flawed against Haskins.
Whilst there is little revealed in regards to the comeback we would expect it to come in Tokyo, probably the Korakuen Hall and in either November or December against a relatively poor opponent. The interesting thing however will be the weight at which Iwasa returns with either a strong possibility being that he comes back at Super Bantamweight rather than Bantamweight. It was something he hinted at in 2014 and may now commit to.
