In 1937, he was transferred to 13th Air Group and flew Yokosuka B4Y bomber. He participated in early stages of Second Sino-Japanese War and was also involved in USS Panay incident in 12 December 1937. In March 1938, Lieutenant Murata was transferred to 12th Air Group and assigned as one of the flight division leaders. There he participated in strikes on Hankou in Central China. In December, he was transferred to carrier Akagi and became flight division leader in torpedo bomber squadron. In June 1939, he was assigned to Usa NAS in Ōita Prefecture on Kyushu and in October he began an advanced training course for torpedo attack specialization at Yokosuka NAS. In November 1940, he was appointed as an instructor at the same NAS and conducted research on torpedo attack technique in shallow waters.
Pacific War
In September 1941, Lieutenant Murata was transferred back to Akagi. He was assigned as torpedo squadron leader and was promoted to Lieutenant Commander. He participated in the Attack on Pearl Harbor, where he commanded the torpedo bombers that crippled Battleship Row. After that, he participated in the Indian Ocean Raid and subsequently in the Battle of Midway. He was on board Akagi when the bomb released by Lieutenant Dick Best hit the carrier and set it afire. In July 1942, Lieutenant Commander Murata was transferred to the carrier Shōkaku and was assigned as its torpedo bomber squadron leader. In late August 1942, he participated in the Battle of the Eastern Solomons, however he did not see any action. For this battle, Vice Admiral Chuichi Nagumo had decided to hold the Nakajima B5N torpedo bombers in reserve, while allocating two waves of Aichi D3Adive bombers to soften up the enemy fleet beforehand. The dive bomber strikes, under Lieutenant Commander Mamoru Seki and Lieutenant Sadamu Takahashi respectively, were launched late in the afternoon, leaving little possibility of launching the torpedo bombers. In late October 1942, Lieutenant Commander Murata participated in the Battle of the Santa Cruz Islands, where he commanded the first strike wave that consisted of 21 D3A dive bombers, 20 B5N torpedo bombers and 21 A6M Zero fighters. The dive bombers were led by Lieutenant Sadamu Takahashi from Zuikaku, while four escorting Shōkaku fighters were led by Lieutenant Hisayoshi Miyajima, eight from Zuikaku by Lieutenant Ayao Shirane and nine from Zuihō by Lieutenant Moriyasu Hidaka. One the way, the IJN strike force encountered a USN strike force on a reciprocal course. At that point, Lieutenant Hidaka and his nine Zeros abandoned the escort duty and attacked the USN aircraft. When the rest of the strike force approached the USN fleet, Murata led an extremely well-coordinated torpedo and dive-bombing attack that achieved three bomb and two torpedo hits on carrier Hornet. The torpedo released by Murata appeared to have been among the two that hit the carrier. However, during the attack Murata's B5N was hit by anti-aircraft artillery and went down in flames. He was one of the many experienced carrier pilots lost in the battle; these included his academy classmate, Lieutenant Commander Mamoru Seki, who led the second wave strike that severely damaged Enterprise. He was posthumously promoted by two ranks to Captain and received a special individual citation from the IJN.
