"Ao" joined SCG Muangthong United in 2015, from Japan's Ventforet Kofu.

He's warmly remembered by Kirin fans for his bravery on the pitch, giving his best even with his head bandaged, while always being professional and a true gentleman.

Aoyama, who announced his retirement through his Instagram page, said he has fond memories of Thailand, the food, drinking out of coconuts, his teammates, but especially the people in general.

He especially remembers competing in the ACL Champions League, playing for Muangthong against his countrymen on Kashima Antlers and Kawasaki Frontale.

"Ao" thanks the club for the opportunity to have played in Thailand.
