Trivia

General Information

• She is named after the Port of Ootomari.
• She was launched on the 3rd of October 1921.
• Originally designed as a Kamoi-class Oiler. The failure of Japan to dispatch ships capable of breaking through the ice to rescue their citizens during the Nikolayevsk Incident caused her redesign as an Ice Breaker.
• Japan had no prior experience in constructing ice breakers, as such they relied on observing designs from other nations, particularly the Soviet Union, and ultimately she was based after the Dobrynya Nikitich.

Update History

• She was added on the 7th of March 2025 as Spring 2025 Event E1 drop.

Misc

• Was assigned to the Ōminato Guard District and took northern patrol duties in the regions of Sakhalin, Kuril Islands and Sea of Okhotsk
• Survived World War II.
• Was initially planned to be a repatriation ship, but her boilers were no longer usable; in fact, she was heading for Youkosuka for maintenance, but the war ended and plans were stopped.
