This week's "Tetsuko's Room":Mari Yoshiko, the first "song sister," still sings children's songs at 86 years old. Is Uji Koji's "Gomen ne, gomen ne" in Tochigi dialect?

The lineup for Tetsuko Kuroyanagi's long-running talk show "Tetsuko's Room" (TV Asahi, Monday to Friday 1pm), which will air from March 24th to 28th, has been announced. On the 24th, actor Kensaku Morita will appear, on the 25th the first "Uta no Oneesan" (song sister) Yoshiko Mari will appear, on the 26th calligrapher Shoko Kanazawa and her mother Yasuko will appear, on the 27th a selection of masterpieces, "Takumi no Aji ~ Affectionate Chefs," and on the 28th, comedy duo "Uji Koji."

Morita-san appears for the first time in 39 years. He is 75 years old, but says his body shape has remained almost the same since his 20s. He says the secret to his health is his wife's home cooking, and that he and his wife Yoshiko, whom he has been married to for 39 years, still call each other "Ken-chan" and "Yoshi-chan."

Mari passed the NHK audition in 1961 and became the first "Uta no Oneesan" (Singing Sister). At 86 years old, she still sings children's songs on stage, and last year won the Japan Children's Song Award Special Prize. She spent her 20s with Kuroyanagi at NHK. This time, she will sing a children's song medley.

Kanazawa-san attracted attention at her first solo exhibition at the age of 20, and it has been 20 years since she was called a "genius calligrapher with Down's syndrome." She started living alone at the age of 30, and last year opened an atelier and coffee shop, where she is currently working as a waitress.

The selected masterpieces, "Masterful Tastes - Beloved Chefs," introduces Kandagawa Toshiro, a Japanese chef representing Naniwa; Suzuki Tokiko, a food researcher affectionately known as "Baba"; Chen Jianmin, a Chinese chef who popularized Sichuan cuisine in Japan; and Chen Kenichi, the "Iron Chef of China" who followed in his father's footsteps.

Uji Koji, a manzai comedy duo that performs in the Tochigi dialect, debuted 25 years ago. They talk about how their gag "Gomen ne, gomen ne" (I'm sorry, I'm sorry) was born. This gag became so famous that it has even been "re-imported" to the point where people in Tochigi Prefecture mistake it for the Tochigi dialect.
