back number – The Curtain Rises [Theme song for the film 'TOKYO MER: Mobile Emergency Room – Nankai Mission']

This is a sweeping, heart-stirring ballad by back number, chosen as the theme song for the theatrical release TOKYO MER: Mobile Emergency Room – Nankai Mission, coming out in August 2025.

Produced with Takeshi Kobayashi onboard, its sense of scale is breathtaking.

The song portrays the decisive moment when, despite being so overcome by fear that one trembles, one still resolves—out of a sense of duty—to head toward someone in need.

Lead actor Ryohei Suzuki has said this worldview gripped his heart; it truly feels like a scene from a film.

Listen to it when you’re facing a major challenge or need to steel yourself, and you’ll receive a warm yet powerful boost of encouragement.
