He was a key member of Japan's Under-23 team, however he failed to join the U-23 squad to compete in the Beijing Olympics football competition.

He was included in the 2011 AFC Asian Cup finals and made his full international debut on 17 January 2011 against Saudi Arabia.

He struggled to adapt to Croatian life, stating reasons such as difficulty to learn the new language and no other Asian players in the side as main factors.

He was fined by the club for missing three training sessions before finally rescinding his contract and returning to Japan in late January 2012.

After Vissel Kobe's relegation from the top tier in Japan in 2012, Inoha then moved to Jubilo Iwata in January 2013 for an undisclosed fee.

He made 25 appearances and scored a single goal in his first season for Iwata in the Japanese first division but unfortunately they finished in 17th place and were relegated.
