We took a late morning train from JR Sapporo Station to Otaru Station, arriving just in time for lunch. To fully maximize the daylight, we decided to skip lunch. In winter, the sun sets in Hokkaido as early as 4 PM, and many attractions, including the Otaru Aquarium, close earlier because of this limited daylight. So, after disembarking from the train, we immediately caught a bus to transport us to the Otaru Aquarium, eager to make the most of our visit.
