Ichimura's agency revealed that Ichimura had complained of feeling unwell in late June and went for a checkup where he was first diagnosed with acute gastritis. However, upon a detailed checkup, it was later determined that he had a malignant tumour in his stomach. In order to concentrate on treatment, Ichimura had no choice but to stop appearing in the musical after his last performance on 27th July and announced the news to the cast on the same night. He is due to be hospitalised for two weeks to undergo laparoscopic surgery before recuperating at home. If all goes well, Ichimura will make his return to work in the musical "Mozart!" in November.
