Southampton striker Tadanari Lee has rejected a permanent transfer at FC Tokyo.
The 27-year-old started just four games, coming off the bench on nine other occasions, but did score four goals during his loan spell in Tokyo.
Lee said: "I felt like I was only playing in fits and starts and thought a different challenge would be better for me.
"Maybe it was a case of me not being good enough. I spoke to the coach and we tried to work something out."
