However, Inoue is not active on X (formerly known as Twitter), as no verified account under his name exists on the platform.
Who is Naoya Inoue’s wife?
Despite being happily married for the past decade, the identity of Inoue’s wife is a safe-kept secret. The Japanese boxer prefers to keep his personal life private and despite marrying his wife in 2015, he has not revealed her identity to the public.
Naoya Inoue’s boxing record
Inoue is arguably the best boxer on the planet and his record in boxing definitely shows that fact. In his 29 fights so far in his career, he has won every single one of them in impressive fashion.
| Record (W-L-D) | (T)KO |
| 29-0-0 | 26-0 |
Additionally, 26 of those came via knockout, including Inoue’s victory over Kim Ye-Joon in January 2025.
Naoya Inoue’s net worth
Reports of Inoue’s net worth vary greatly between different sources, with numbers as little as $7 million all the way up to $42 million being claimed.
However, it was reported that he will earn around $7 million for his fight against Ramon Cardenas, so the real number is likely to be closer to the latter, rather than the former.
Naoya Inoue’s next fight
Inoue’s next fight will be against Cardenas in Las Vegas on May 4th. The undefeated Japanese fighter will be looking to get his 11th knockout in a row, although he will face fierce competition from the American fighter.
Cardenas has 26 wins to his name and only 1 defeat, putting him in good stead to take on “The Monster”.
A victory over Inoue would be a huge shock, although he will be dreaming about taking home the undisputed Junior Featherweight world title when the pair meet in Inoue’s first US fight in four years.
Naoya Inoue vs Sam Goodman
A fight between Inoue and Sam Goodman was planned for January 24, 2025, for the Japanese fighter’s undisputed title.
However, a sparring injury caused a cut on Goodman’s face and the Inoue/Goodman fight was postponed, with no date for the rearranged fight decided as of May 2025.
Kim Ye-Joon faced Inoue instead, and was promptly stopped in the fourth round with a big knockout.
