Koki Ando

Ahead of the J1 100 Year Vision League, Ando signed for Japanese side Mito HollyHock, where he made eight league appearances and scored two goals. During the spring of 2026, he trained with German side Hannover 96, who the club had a partnership with. On 24 April 2026, he debuted and scored his first goal for Mito HollyHock during a 2–5 away loss to FC Tokyo in the league. On 29 April 2026, he made his second league appearance and scored his second goal for them during a 2–2 home draw with and 5–6 loss on penalties to Machida Zelvia in the league. Following his stint there, he signed for Belgian side Antwerp the same year. The transfer received skepticism from some Japanese commentators, who felt the move to a European league was too early.

Ando plays as a winger, is right-footed, and has received comparisons to Japan international Kaoru Mitoma. Japanese news website Yahoo Japan wrote in 2026 that "his strength lies in his ability to break through using his speed. He uses his explosive speed to cut through the side and attacks the goal in an aggressive playing style".
