On June 23, ''Nōmi'' was released from the Yokosuka Naval District Operation Command and was removed from the Yokosuka Maritime Escort Flottila. On the 23rd of the same day, under the command of Operation Ominato Guard ( Lt. Gen. Yasuo Inoue, Commander-in-Chief), she was transferred to the military division maritime escort unit.

On the 27th, ''Nōmi'' arrived in Ominato, Aomori Prefecture.

She arrives in Wakkanai, northern Hokkaido, on June 30. Since then, ''Nōmi'' has cooperated with the Northeast Area Fleet and engaged in convoy escort, patrol, and rescue in the Sakhalin, Kuril Islands, and Hokkaido areas. The 2nd Maritime Escort Flotilla, to which ''Nōmi'' belonged, was crushed in the Battle of Saipan because she had a headquarter on Saipan Island, and was dismissed on July 18.

On September 5, ''Nōmi'' and ''Namikaze'' escorted the Ki-505 fleet and departed from Otaru. On the night of the 8th, ''Namikaze'' was sunk by USS ''Seal'', and her hull was cut off, making her inoperable. ''Nōmi'' was wary of the surroundings of the wave breeze and suppresses anti-submarine. The Ominato Guard Office dispatched destroyers such as ''Nokaze'' to rescue ''Namikaze'' and ''Kokugo Kaibo'' to escort the Ki-505 fleet. However, during this time, the Ki-505 fleet was unprotected. After that, ''Namikaze'' was towed by ''Kamikaze'', and was escorted by destroyer ''Nokaze'', ''Kaibokan Hachijo'' and ''Fukue'' (cooperating with escort from the middle) in Otaru.

On the morning of the 10th, ''Nōmi'' passed the ''Shonan Maru'', but she couldn't find any survivors. The 4 Ki-505 fleets, which had lost her escort, had been evacuated to Sakhalin Kaori, so ''Nōmi'' and ''Kunashiri'' moved there. ''Nōmi'' housed the survivors of the ''Shonan Maru'', who had escaped on a large motorized boat. On the 15th, ''Nōmi'' and ''Kunigo'' continued to escort the Ki-505 fleet and set off Shiki. She arrived at Paramushir Island Kataoka Bay on the 22nd. On the 24th, she escorted the 403 fleet and left Kataoka Bay. ''Kunigo'' and ''Nōmi'' were divided by 18 of her passengers, 4 prisoners of war and 5 guards. The USS ''Searaven'' was operating in the same direction, and had already sunk the transport ship ''Riyama Maru''.

On the morning of the 26th, the Wo-403 fleet, which was escorted by ''Kunigo'' and ''Nōmi'', were dispersed due to thick fog at latitude 47 degrees 7 minutes north latitude 151 degrees 35 minutes east longitude. ''Nōmi'' searches for the missing fleet. From midnight on the 26th to early dawn on the 27th, ''Nōmi'' engaged with an enemy submarine at latitude 45 ° 44'N and longitude 148 ° 41'E, north of Etorofu Island, killing 7 people and injuring 16 seriously and lightly. She was hit by numerous bullets, and she was sent to Ominato for emergency repairs. She arrived in Otaru on the 29th. She departed Otaru on October 1 for a round trip to Ominato.

Along the way, she goes through Quinone Bay and Tourane, and the fleet calls at Hong Kong on the 24th to repair ''Nōmi''. On the 26th, ''Nōmi'''s repairs were completed and the fleet departed from Hong Kong and arrived at Moji on March 8. She made a round trip to Kure on the same day and carried out repairs and maintenance, including weapons replacement, at the Kure Naval Arsenal. In the description of "The 1st Escort Flotilla (Kaibokan Noumi) War Diary", the Type 94 Depth Charge Projector was removed during the repair in Kure to make it a Type 3 Depth Charge Projector, and the underwater probe was tentatively called the Type 3 Depth Charge Projector. It is said that it was replaced with Kai II and equipped with No. 1 radio wave detector type 3 Kaiichi.

It was designated as the flagship of the 1st Escort Flotilla on March 20, under repair in Kure, and was boarded by Captain Akira Ikeda, Commander of the Sea Defense Corps. She was repaired on April 2 and she was docked. She maintained and commissioned until the 8th, and on the 9th she was circulated to Moji. On the 11th, the escort group (''Nōmi'', '' Miyake'', ''No. 31'' Kaibokan) escorted the Moshi-02 fleet (special transport ship ''Toyama Maru'', 3,943 tons, about 400 passengers) and departed from Moji. On the afternoon of the 13th, the Moshi-02 fleet unit arrived at the harbor on Jeju Island, and three escorts (''Nōmi'', ''Umi 31'', ''Miyake'') were to take turns on patrol.Miyake Senki 2013, p. 165. Before dawn on the 14th, the torpedo attack of USS ''Tirante'' that invaded the harbor caused a large explosion and sank the ''Toyama Maru''. ''Nōmi'' pursued ''Tirante'', but one of the two torpedoes fired by ''Tirante'' hit directly under ''Nōmi'''s bridge. ''Nōmi'''s ammunition detonated due to the explosion, and her hull was cut off and sank.Miyake Senki 2013, p. 166. About 130 crew members, including Colonel Ei Ikeda, commander of the 1st Escort Flotilla, and Major Saburo Agen, the captain of the Escort Corps, were killed in action. ''Tirante'' fired her last torpedo at her chased ''No. 31'' Kaibokan. The torpedo she hit did not explode, but the impact triggered a depth charge on the ''No. 31'' Kaibokan, which capsized and sank (39 killed in action). The only surviving ''Miyake'', along with her supportive Kaibokan '' Aguni'' and No. 39 Kaibokan, carried out an anti-submarine sweep, but failed to capture ''Tirante''.

On May 25, ''Nōmi'' was removed from the Imperial Japanese Navy.
