This is a very popular JR collaboration series every season! Pajamas made of T-shirt material. Featuring an all-over print of the popular Shinkansen Hayabusa, Doctor Yellow, and Alpha-X! The buttons on the sides of the shirt and the loops on the inside of the pants' waist prevent the stomach from being exposed while sleeping. #HungryHeart #HungryHeart #ShinkansenPajamas #Pajamas #Shinkansen
