Jack advertising poster. The cover features an illustration by popular illustrator Gemi. This work is a literary novel by Chiba-born author Takahashi Yuta. It is a moving story set on the Kururi Line, which runs through Chiba’s Uchibo region, depicting the people who visit the fictional Kururi Station. The Kururi Line, which runs from JR Kisarazu Station to Kazusa-Kameyama Station, is a rare local line in the Tokyo metropolitan area, with 11 of its 14 stations unmanned. Kururi is a mysterious train station where loved ones await, and Kururi, a black and white tuxedo cat, invites passengers there. While both are fictional, we hope you will immerse yourself in the world of the novel while thinking about the real Kururi Line and Kururi Station. Synopsis The Kururi Line is a local train that runs through Chiba Prefecture. Occasionally, a black and white cat rides on board. The cat gets off at Kururi Station, which is not on the train map. As if being invited, the traveler follows the cat and passes through the ticket gate to a nostalgic town where a precious person they will never see again is waiting for them… This is a series of short stories depicting the emotional regeneration of the protagonists, who have not been able to recover from a sad separation – their first love, their beloved mother, their beloved owner. The Kururi Line is the only
non-electrified JR East line in Chiba Prefecture. ~Omitted~ In other words, there are no power lines to supply power to the trains. Even though it’s just that, it makes me feel like I’ve arrived in a faraway, unbounded world. A world without power lines was refreshing. Feeling the vibrations of the diesel engine, I gazed aimlessly out the window. A peaceful rural landscape unfolds, and fields of beautiful yellow blooming rapeseed flowers flow by. Slowly, slowly, Satomi is carried along. (Text: Excerpt from Episode 1, “Wedding Bells of That Day”) Across the five episodes, there are descriptions of places and landmarks related to the Kururi Line, such as Kimitsu City and Kisarazu City, and descriptions of the Kururi Line also appear throughout the text, adding depth to the story. This time, we wanted to introduce the world of this work to the actual Kururi Line, so we planned to take over the in-car poster advertising.
