"I really wanted to see Totti pull on a Verdy uniform," said Hanyu. "It would have been exciting. But it's ended without us even sitting down to meet."
Despite interest in his services, retirement still remains an option for the striker, who made his debut for Roma as a 16-year-old in a 2-0 win over Brescia in 1993.
Totti made 786 appearances and scored 307 goals for Roma in a glittering 25-year career, and won the World Cup with Italy in 2006.
He won the Serie A title in 2001 and twice won the Coppa Italia and a role as a club executive at Roma looks likely, according to Italian media.
Japanese first division side Vissel Kobe bucked a trend of high-profile players moving to China when they signed German World Cup winner Lukas Podolski earlier this year.
Kobe's swoop for the former Arsenal striker also represented something of a coup for the J-League, which once attracted luminaries such as Zico and Gary Lineker when it began in 1993 but has struggled to acquire big-name players in recent years.
