The East Kainji languages are spoken in a compact area of the Jos Plateau in Nigeria, near Jos. There are more than 20 of them, most of which are poorly studied.

History East Kainji languages are less internally diverse than some of the other Plateau branches in the Nigerian Middle Belt (Blench 2007). Historically, the East Kainji branch had been influenced by Chadic languages that no longer exist in the region.Blench, Roger. 2007. Language families of the Nigerian Middle Belt and the historical implications of their distribution. Presented to the Jos Linguistic Circle in Jos, Nigeria, July 25, 2007. Today, there are at most 100,000 speakers of East Kainji languages, with almost all languages of the languages being threatened by larger languages such as Hausa and English. Although they are morphologically simple, they have 4-level tones instead of the 3-level tones typical of the region.

At the time of the British conquest, several of these languages were in the process of shifting from duodecimal to decimal systems. Languages attested with such systems include Janji, Gure-Kahugu (Gbiri-Niragu) and Piti.Shuji Matsushita, "Decimal vs. Duodecimal: An interaction between two systems of numeration"

Features Compared to the neighbouring Plateau languages, East Kainji languages are morphologically simple. They have four level tones, as opposed to most other languages in the Nigerian Middle Belt having only three level tones. The fourth tone in East Kainji languages originated as a superhigh tone used to mark plurals.

Syllables in East Kainji languages are generally open (CV). Blench (2020) suggests that the East Kainji branch is most closely related to Basa, since both have (C)V-CVCV phonotactic structures.

Classification East Kainji was once thought to be a primary branch of the Kainji languages, but this is no longer the case. Impressionistically, Piti and Atsam appear to be distinct, but the rest form a continuous dialect chain.Blench 2004, The status of the East Kainji languages of Central Nigeria, p. 8

The East Kainji languages have historically undergone influence from non-Hausa West Chadic languages. East Kainji is not as internally diverse as West Kainji.

Ethnologue Ethnologue indicates several branches; these will be retained here for reference:

Piti–Atsam Jos languages: Amo (Map) Northern Jos languages: Jera languages: Lere, Ziriya (Sheni?) Lameic languages: Gyem, Shau Ningic languages: Gamo-Ningi, Kudu-Camo North-Central Jos languages: Iguta (Guta), Janji, Tunzuii (Tunzu) Boze-Loro languages: Jere, Panawa Chokobo-Lemoro-Sanga languages: Izora (Zora) Lemoro-Sanga languages: Lemoro, Sanga Kauru languages: Kurama, Gbiri-Niragu (Gure-Kahugu), Bina, Dungu, Kaivi, Kinuku, Kono, Mala, Ruma, Shuwa-Zamani, Surubu, Tumi, Vono

Blench (2012) In Blench's 2012 classification, Piti–Atsam is named "Southern". Northern Jos is named "Jos", and the Jera languages are named "Northern Jos", which he further subdivides into several dialect clusters; Amo is placed in this group.Blench 2004, The status of the East Kainji languages of Central Nigeria, p. 10

In the tree below given by Blench (2012), East Kainji is split into a core Jos group and peripheral Southern group.

Southern group: Piti, Atsam Jos group (Jera): Lere cluster: Si (almost extinct), Gana (almost extinct), Takaya (almost extinct) North-central cluster:, Izora (Cokobo), Lemoro, Sanga, Janji, εBoze (Buji), iGusu, iZele (Jere), iBunu (Ribina), iPanawa-iLoro, Iguta, Tunzu (Duguza), tiMap Sheni cluster: Ziriya (extinct), Kere (extinct), Sheni (almost extinct) Kauru group: Gbiri-Niragu, Shuwa-Zamani, Surubu, Kurama, Mala-Ruma, Bina, Kono, Kaivi, Vono, Tumi, Kinuku, Dungu Northern group (Ningi-Lame): Ningi cluster: Kudu-Camo (almost extinct), Gamo-Ningi (Butu-Ningi) (†) Lame cluster: Gyem (almost extinct), Shau (almost extinct)

Shimizu (1982) Classification of the Northern Jos group according to Shimizu (1982: 165):Shimizu, Kiyoshi, 1982. Die North-Jos Gruppe der Plateau=Spreachen Nigerias. Afrika und Übersee, vol. 65.2 (1982), 161-210.

Shimizu (1982) also reconstructs Proto-Northern Jos.

Glottolog Glottolog's classification is similar to Blench's, but the Piti–Atsam name is retained. In this classification, all languages except for Piti–Atsam are grouped under "Jos". Amo, while within the "Jos" group, is left out of both Kauru and Jera (or "Northern Jos", following Blench).

Only Kurama, Gbiri-Niragu, Jere, Sanga and Lemoro have more than a few thousand speakers.
