At the time of the attack on Pearl Harbor, Yudachi was assigned to Destroyer Division 2 of Destroyer Squadron 2 of the IJN 2nd Fleet together with her sister ships Murasame, Harusame, and Samidare, and had sortied from Mako Guard District as part of the "Operation M" (the invasion of the Philippines). From January 1942, Yudachi participated in operations in the Netherlands East Indies, including the invasions of Tarakan, Balikpapan and eastern Java. During the Battle of the Java Sea, Yudachi engaged a group of Allied destroyers and cruisers. Returning to Subic Bay in the Philippines on 16 March, Yudachi assisted in the blockade of Manila Bay and the invasion of Cebu, returning to Yokosuka for repairs in early May. During the Battle of Midway on 4–6 June, Yudachi was part of the Midway Occupation Force under the overall command of Admiral Nobutake Kondo.

From mid-June, Yudachi deployed from Kure via Singapore and Mergui for raiding operations in the Indian Ocean, but the operation was cancelled due to reverses suffered by the Imperial Japanese Navy in the Solomon Islands. Yudachi arrived at Shortland Island on 30 August, and was immediately assigned to "Tokyo Express" high speed transport runs to Guadalcanal. During one such mission from 4–5 September, Yudachi assisted in the sinking of the destroyers USS Gregory and USS Little. Yudachi continued making missions to Guadalcanal through November, participating briefly in the Battle of the Santa Cruz Islands on 26 October under Admiral Takeo Kurita.

On the night of 12–13 November 1942, in the First Naval Battle of Guadalcanal, Yudachi escorted the Bombardment Force of Rear Admiral Abe Hiroaki. The lead ship in the formation at beginning of battle, Yudachi had to swerve to avoid U.S. ships, then torpedoed the cruiser USS Portland. Yudachi then mistook the destroyer USS Sterett for a friendly ship and flashed its recognition signals. Sterett fired back, hitting Yudachi's #1 boiler room, leaving the ship dead in the water. After Yudachi was disabled, 207 survivors were removed by Samidare, which then failed to scuttle her with three torpedoes.[6] The abandoned hulk was later sunk by gunfire of Portland, southeast of Savo Island at position (09°14'S 159°52'ECoordinates: 09°14'S 159°52'E). According to James Hornfischer, Yudachi was showing a white flag before Portland fired, but this was deliberately ignored by the American captain, who directed his gunnery officer to "sink the S.O.B." probably due to the Japanese shelling the helpless survivors of USS Gregory and USS Little.
