[5][6][7] An influential figure in fifth-generation Congolese rumba, Bondongo began singing at 10 years old and soon joined JB Mpiana's Wenge BCBG for practice and public appearances, seeking membership but was eventually repudiated.

[8][9][10][11] Bondongo gained widespread recognition after joining Werrason's Wenge Musica Maison Mère in 2001, where he co-wrote and sang on several of the band's most breakout songs, including "J'en ai assez" (2002), "Nostalgie" (2002), "Demi-Tour" (2005), "Simeon" (2006), "Confession Intime" (2008), "Sol De Mi Amor" (2008), "Par Amour" (2009), "Remise et reprise" (2011), "Le prince de la ville" (2011), "Amour vrai" (2014), and "Kimberny meilleur choix" (2014).

[26] He has cites Debaba, Papa Wemba, JB Mpiana, Franco Luambo, Tabu Ley Rochereau, King Kester Emeneya, and Madilu System as his early musical influences.

[24] At the age of 14, he met Papy Kakol and Fila Basele, and they would often attend rehearsals of the Kinshasa-based band Kibinda Nkoy alongside Fally Ipupa, Seguin Mignon, and Blanchard Mosaka.

[24] Sankara introduced Watanabe to Werrason, who, after testing him on various songs, decided to visit his family to request permission to mentor him in Wenge Musica Maison Mère and ensure that he continued his education as his mother insisted on his completion of the baccalaureate.

[24] Upon the band's return to Kinshasa, he was involved in the preparation for Werrason's 2001 debut album Kibuisa Mpimpa, though he could not join the recordings in Europe because of his exams at the Institut Superieur d'Informatique, Programmation Et Analyse (ISIPA).

[24] In 2002, when he was introduced to the public, going by the name "Héritier Gucci", he participated in Werrason and Wenge Musica Maison Mère's double sold-out concert at Zénith de Paris on 26 and 27 April at only 19 years old.

[34][24][36] Alerte Générale signified the dawn of a new era for Wenge Musica Maison Mère, with Watanabe stepping up as the band's director, supported by drummer Papy Kakol.

[24] In 2005, Werrason released his second solo album, Témoignage, and Watanabe co-led the song "Demi-Tour" alongside him, filling in for the musicians who departed the previous year.

1, titled "Confession Intime" (which was initially meant for Sous-Sol, but Werrason decided to limit the maxi-single to five songs) and "Sol De Mi Amor".

[27] On 11 June 2011, Wenge Musica Maison Mère, Fally Ipupa, Magic System, Meiway, Jessy Matador, Patience Dabany, Coumba Gawlo, Oumou Sangaré, Sekouba Bambino, Petit Pays, Passi, Mokobé, Baaba Maal, Alpha Blondy, Manu Dibango, Mory Kanté, and other artists took part in the Nuit Africaine event at the Stade de France.

1 was released, where Watanabe signed the song "Remise et reprise" and led the entire first part of "Le prince de la ville" written by Werrason.

Without a doubt, Werrason is a great trainer full of talent..."[43][44] On 29 April, he held his first rehearsal with his newly formed orchestra, Team Wata, during which he was visited and supported by his former bandmate Bill Clinton Kalonji.

[51] Watanabe officially presented the album during an event at the Béatrice Hotel in Kinshasa on 10 February 2017 and later signed an endorsement deal with Skol beer on 25 March.

However, just two days before the event, the venue submitted a request to the Paris Police Prefecture to cancel the concert due to threats from Combattants—a dissent faction opposed to President Joseph Kabila and Congolese musicians allied with him—who threatened to carry out a "new Bataclan" attack if Watanabe performed.

[57] Although the prefecture initially permitted the concert to proceed, imposing time restrictions and prohibiting demonstrations, disturbances on the day of the event, including vehicle fires near Place de l'Opéra, led Paris Police Prefet Michel Delpuech to cancel the show.

[67][68][69] Despite the initial April 2019 release target, the album faced several delays, with the launch postponed to December 2019 and then further pushed to January 2020 as the final touches were made in Paris.

[70][71][72] On 11 October 2020, Watanabe announced the release of the first single from Mi-ange mi-démon, titled "Désolé", which tendered an apology for the sexual controversies and legal issues that have besmirched his public image.

[83] Four months later, Watanabe was selected as one of four artists by Minister of Tourism Modero Nsimba Matondo to join the 24th UNWTO General Assembly in Madrid, Spain, to showcase Congolese culture and promote the DRC as a tourist destination through his music and live acts.

[88] Watanabe also delivered a performance at the closing of the International Tourism Fair in Madrid on 22 January 2022, then appeared in Istanbul, Turkey, on 19 February at the Gar Musichall,[89][90][91] and followed with a concert at Millionaire Club in Kinshasa.

[92] On 17 March, he appeared on the single "Leopards Fimbu International" to rally support for Les Léopards in the 2022 FIFA World Cup qualifiers' playoff stage, with artists Félix Wazekwa, Flaety W. Manuke, Lokua Kanza, Kadiyoyo, JB Mpiana, Barbara Kanam, Koffi Olomide, Cindy Le Cœur, Kristy Diamond, Laetitia Lokua, Adolphe Dominguez, Werrason, Lemiran LEM, Ferré Gola, and Innoss'B.

[100][101] However, during their performance, Watanabe addressed the audience, conveying that their set would not proceed as expected due to a mishap involving Team Wata's key members in Equatorial Guinea and noted that he had to enlist additional musicians for the show.
