On Japan’s most scenic train, a murder is about to rewrite history. Dr. Akira Tanaka, a cultural anthropologist, boards the Oigawa Railway expecting a quiet ride through Shizuoka’s legendary tea mountains. Instead, he finds himself seated across from Yuki Sato — a manga artist whose prophetic sketches predict crimes with terrifying accuracy. Her latest vision? A tea master stabbed to death during the on-board ceremony. When the prophecy comes true in a cloud of steam and green tea, panic erupts. But the murder is only the opening act. Each mile of track pulls Akira and Yuki deeper into a conspiracy that stretches far beyond the train — a billion-yen scheme to erase centuries of Japanese tradition and replace it with soulless tourist resorts. Family betrayals. Stolen land. Academic corruption. Every passenger is a suspect, and every tea scoop, scroll, and whispered ritual could be a weapon. Part locked-room mystery, part cultural thriller, The Tea Mountain Express is a breathtaking ride where art reveals the truth and heritage is worth killing for. Once the wheels start turning, there’s no getting off this train alive.
