The Type 91 surface-to-air missile (91式携帯地対空誘導弾, 91-shiki Keitai Chitaikū Yūdōdan) is a Japanese man-portable air-defense system (MANPADS).

[8] The Type 91 is currently exclusively used by the JSDF and has not been exported overseas to date due to previous interpretations of post-war constitutional restrictions and the laws arising from them.

[10] In 1982, the Japan Self-Defense Forces began looking for a replacement for the FIM-92 Stinger which was then in service via Foreign Military Sales.

[16] The adoption of the Type 91 allowed the JSDF to gradually retire the Stingers, with the last stocks officially removed from active JGSDF service in 2009.

[16] On launch, the missile records the target's image profile and is able to ignore defensive countermeasures such as flares.

[19] The Type 91 comes with the rocket launcher, an external battery pack, IFF system, missiles and other training equipment.
