NANGA Unveils 'Doctor Yellow' Sleeping Bag Project

NANGA Co., Ltd. (NANGA) and Central Japan Railway Company (JR Central) have launched a crowdfunding project for the 'Doctor Yellow SLEEPING BAG,' the first official collaboration between the two companies.

Maibara City in Shiga Prefecture, where NANGA is headquartered, is a town deeply connected to the line once traveled by the Doctor Yellow (T4 formation), which retired in January of last year.
