January features unique events on both ends of the route: in Tokyo, New Year’s (Shogatsu) observances, Hatsumode shrine visits, Coming of Age Day (Seijin no Hi, second Monday of January), and the January Grand Sumo Tournament (Tokyo Ryogoku Kokugikan) attract visitors. Winter illuminations continue into January in Tokyo and Yokohama. In Boston and New England, January offers winter festivals, ski openings in the White Mountains and Green Mountains, and Boston’s winter restaurant weeks—ideal for pre-departure short trips from Boston Logan International Airport (BOS).
