Takeshi Kishida debuted as captain of Yamabuki Elementary School's soccer team. During Nankatsu city team selections, he competed against Ryo Ishizaki and Kazuo Urabe but faced defeat against Taro Misaki, acknowledging Misaki's superior skill. This earned him a place as a regular defender on the Nankatsu city selection team. Progressing to Otomo Middle School alongside Urabe, Kishida formed the "Otomo Quartet" with Koji Nishio and Masao Nakayama. The quartet undertook intense daily training, running at least 30 kilometers to challenge elite players like Tsubasa Ozora. Despite their efforts, Otomo lost to Nankatsu in the middle school nationals. Kishida later cheered as a spectator for Japan during the International Jr. World Cup in Europe. For high school, Kishida transferred to Nankatsu High School with Urabe. He participated in the middle school national tournament, encountering rivals such as Kojiro Hyuga's Toho Academy. During the World Youth Asian preliminaries, he played in the first round while main regulars trained individually, sustaining an injury during eager defensive play. His international appearances were limited, with no recorded goals or assists across tournaments. Kishida's professional career started with Shimizu S-Pulse in the J1 League. He continued representing Japan on the U-23 team for the Madrid Olympics preliminaries and later the Olympic squad. His playing style centered on defense, featuring a diving "shark tackle" inspired by his surname's meaning ("coast" or "shore"). He holds the series record for most games played without scoring or assisting. Physically, Kishida grew from 147 cm and 40 kg in elementary school to 172 cm and 64 kg in high school. He wore jersey #24 for Japan Youth, primarily playing as a full-back defender or defensive midfielder (DMF). His technical attributes included Defense (72), Technique (71), and Speed (67), with the "Otomo Quartet" as his signature collaborative move. Kishida maintained long-term partnerships with Urabe, Nishio, and Nakayama, collectively known for rigorous training and teamwork. His career spanned 20 matches across 1,111 minutes of playtime, with a 70% win ratio during elementary school that decreased in later stages.
