Fuji TV's popular medical drama "Kyumei Byoto 24 Ji" is coming back for a fourth season. Starring Yosuke Eguchi (41) and Nanako Matsushima (35), the show premiered in 1999 and had additional seasons in 2001 and 2005.

Eguchi and Matsushima will reprise their roles as emergency room doctors. Matsushima has not had a regular TV role since the drama's third season in 2005 (though she had a guest role in both seasons of "Hana Yori Dango"). This also marks her first series since having her second child in November 2007, just as the third season was her comeback work after giving birth to her first child in 2004.

Yusuke Santamaria (38) will join the cast for this season, playing a rival doctor. Other cast members include Tae Kimura (38), returning in her role as a nurse from the second season, and Kie Kitano (18) as a rookie nurse.

Fuji TV has scheduled the drama for Tuesday nights at 9:00pm, starting on July 7.
