Personally I will say : 1- Ryosuke Nishida 2- Kosei Tanaka / Seigo Yuri Akui 3- Shuichiro Yoshino 4- Mikito Nakano 5- Ginjiro Shigeoka 6- Masanori Rikiishi 7- Yudai Shigeoka 8- Yoshiki Takei 9- Andy Hiraoka 10- Ryang Ho Han / Reiya Abe
My pick isn't on the list. I'd say Kazuto Ioka. Andy Hiraoka would be next. Akui out of the guys on the list
Akui is also very underrated he is the number 2 in Flyweight and no one talk about him it's not like Kazuto Ioka who is very famous in the contrary.
Kazuto Ioka is very famous, but I had him in my top 5 pound for pound at a point. Didn't see him that high on about 95% of other lists, so I view his career quite differently than most people
