JS Taigei (SS-513) is the first boat of the Taigei-class attack submarine of Japan Maritime Self-Defense Force. The submarine was ordered from Mitsubishi Heavy Industries in 2017 and laid down on 16 March 2018 at Kobe, Japan. Taigei was launched on 14 October 2020.

The Taigei-class submarines (29SS) are a new class of attack submarines developed for the Japan Maritime Self-Defense Force. It is the successor to the Sōryū class.

The hull design of the Taigei class is said to not differ too much from the Sōryū class but will be 100 tons heavier than its predecessor. However, the Taigei-class submarines will be more advanced as they are equipped with newer equipment such as sonar systems, snorkel power generation system.

The Taigei class will use lithium-ion batteries much like the JS Ōryū and JS Tōryū submarines.[24] The submarine will likely use the Type 18 torpedo, which project name as "G-RX6".
