The opening film for this year¡¯s Tokyo International Film Festival seems better suited for a weekday matinee screening at a second-run theater. Junji Sakamoto¡¯s ¡°Climbing for Life¡± is a perfectly watchable biopic that mostly avoids corniness, but it can¡¯t resist the gravitational pull of its star, Sayuri Yoshinaga.

The 80-year-old actor (making her 124th screen appearance) is a national institution in Japan ¡ª though she doesn¡¯t enjoy the same recognition overseas. ¡°Climbing for Life¡± is unlikely to change that: While it¡¯s more restrained than the tearjerkers that have defined Yoshinaga¡¯s career, it¡¯s just as old-fashioned in its sensibilities, redolent of Yoji Yamada¡¯s heartwarming dramas.

Yoshinaga plays Junko Tabei, who in 1975 became the first woman to summit Mount Everest as part of an all-women Japanese team. Riko Sakaguchi¡¯s screenplay weaves an account of that expedition into a story focusing on the final years of Junko¡¯s life, after she is diagnosed with terminal cancer. Refusing to go out without a fight, she starts organizing trips to Mount Fuji for high school students affected by the Great East Japan Earthquake of 2011.
