"Kainan Maru" then sailed further east, in an attempt to pass the most easterly longitude, 152°W, recorded by Scott's "Discovery". They reached 151°20'W, thus exceeding Scott's mark by a distance calculated as 17.3 km (11 miles). On the way back to the Bay of Whales they paused at a small bay which they named Okuma Bay in honour of the expedition's patron. On 1 February they arrived at the Bay of Whales, but ice conditions prevented them for two days from beginning the embarkation of Shirase's party. Deteriorating weather made this operation a fraught and hurried process, and resulted in much being left behind including, much to the men's distress, all the dogs. Shirase remembered these abandoned dogs in his daily prayers for the rest of his life. "Kainan Maru" left the bay on 4 February.
