75th NHK Kohaku Uta Gassen, broadcast live from NHK Hall in Shibuya, Tokyo, saw its second part (9:00 p.m.–11:45 p.m.) achieve an average household viewership rating of 32.7% in the Kanto region, according to Video Research. This marks the lowest rating since 2011's 31.9% and continues the trend of the event failing to surpass 40% for four consecutive years.

Despite the decline, the night featured memorable performances, including first-time appearances by ME:I, Number_i, and Creepy Nuts, alongside returning legends such as THE ALFEE, GLAY, and Hikawa Kiyoshi. Special guest B’z made a surprise in-person performance, delivering their drama theme song "Illumination" and classics like "LOVE PHANTOM."
