Ishihama is a right-side defender for ETU. Like many of the younger players, he became a regular under Tatsumi but is not as skilled as the defensive pair of Yusaku Sugie and Kazuki Kuroda. Ryo Akasaki especially is disparaging of their skills and even accused him and Kazumi Kiyokawa of playing only for fun and not to win. Ishihama left ETU for Vanguard Kofu during the summer break. His reason for doing so was that he realised that he had become too compliant in ETU and had stop improving. Kofu wanted to buy Ishihama permanently but Goto only agreed to a loan. However, Ishihama said he was going to work under the assumption that he was never going to return to ETU.
