Japan Post will begin selling its Nagaragawa Railway 40th-anniversary Frame Stamp sheet on 11 November 2026, following an announcement on 4 November. The offering is 700 sheets, each containing ten ¥110 stamps and priced at ¥1,750 including tax.

The sheet pairs a large photograph of an orange train crossing a river bridge with smaller railway scenes. These show trains beside cherry blossoms and autumn foliage, a winter scene, a blue train, a station platform and a crowded station gathering. The illustrated labels include the Nagara sightseeing train and Gujō-Hachiman Station.

Counter sales cover 64 post offices in Kakamigahara, Seki, Mino, Gujō and Yamagata, plus Tomika and Minokamo Ōta Honmachi offices, excluding some agency offices. Online sales begin at 00:15 on 15 November; postage is additional.
