LOST10 (2026 Japanese Drama)

LOST10 is a Japanese human-suspense drama set in Hokkaido’s rugged wilderness, following detective Komoma as he investigates the “Shikaradake Incident,” a climbing-tour accident that leaves one guide and five participants dead. As conflicting testimonies, betrayals, and powerful forces threaten to bury the truth, Komoma uncovers that all tour participants were insured, with Aya as the beneficiary turning the case into a suspected insurance-murder plot. Across the season, the tangled fates of those involved are tested as layers of “lost” truths are peeled back.
