Tottenham have agreed a deal to sign Japan international defender Kota Takai from J1-League side Kawasaki Frontale, according to the Press Association.
The 20-year-old will move to north London in July for a £5million fee and will compete in central defence with Micky van de Ven, Cristian Romero, Kevin Danso and Radu Dragusin.
He made his international debut in September in a 7-0 World Cup qualifying win over China having helped his club side to an eighth-place finish domestically last season.
Despite the seemingly modest sum, though, his £5m transfer to Tottenham will become the record sale for a Japanese player from the J1-League.
