See main article: Hyūga-class helicopter destroyer. They are sometimes referred to as an aircraft carrier (helicopter carrier) from the ship's type of flight deck,[1] but officially follows the predecessor Haruna-class destroyer, and as they are also a helicopter destroyer. In addition to advanced command and control capabilities, the ship itself has powerful anti-submarine and anti-aircraft combat capabilities due to the vertical launch system that can launch anti-submarine and anti-aircraft missiles and the newly developed C4ISTAR system. Instead, the function as an escort ship that can perform anti-submarine warfare with its own equipment is also emphasized. This point is one of the features that is significantly different from the Izumo-class helicopter destroyer, which specializes in on-board helicopter operation, with only the minimum weapons for self-defense (two each for close-range air defense missiles and high-performance 20 mm machine guns).[2]
They have the ability to operate a large number of helicopters at the same time due to its vast full deck and large hull volume. As a result, it has superior zone anti-submarine warfare capability than conventional helicopter-equipped destroyers, and can also handle transport helicopters and rescue helicopters. Respond to various missions such as support.
Since the hull size is larger than some conventional light aircraft carriers and amphibious assault ships, it may be compared with light aircraft carriers that operate STOVL aircraft such as the F-35 and Harrier. However, the Japanese Ministry of Defense has not announced the operation of fixed-wing aircraft in the model, and Yoji Koda, a former fleet commander of the JMSDF, states that the ship is completely different in nature from an aircraft carrier.

The welcome ceremony was attended by officials such as the local mayor.[14] On December 1, Ise sailed south of Yakushima, Kagoshima Prefecture, in search of a man in his forties who fell into the sea from the JS Kongō the day before. Around 4 am on the 1st, the crew of Ise discovered him drifting about 50 km south of Yakushima, clinging to a drifting object such as a cooler box, and were able to rescue him.[15]
She was placed under the command of the Mine Warfare Force commander during training with the U.S. military (Talisman Saber 19), which was conducted from June 3 to August 21, 2019 at the Shoalwater Bay Exercise Area in Queensland, Australia and the surrounding waters.

Ise alongside took part in RIMPAC exercise in the waters near Hawaii from August 17 to 30 of 2020. Both ships arrived two weeks before the start of the exercise.[17] [18] In September 2023, the first landings by Ground Self Defence Force (JGSDF) V-22 aircraft were conducted on the helicopter carrier. The landings were part of efforts to strengthen inter-operability and create the JGSDF's Amphibious Rapid Deployment Brigade for the purpose of better defending Japan's southern Nansei Islands.[19]
