We present the J - and K _ { S } -band galaxy counts and galaxy colors covering 750 square arcminutes in the deep AKARI North Ecliptic Pole ( NEP ) field , using the FLoridA Multi-object Imaging Near-ir Grism Observational Spectrometer ( FLAMINGOS ) on the Kitt Peak National Observatory ( KPNO ) 2.1m telescope .
The limiting magnitudes with a signal-to-noise ratio of three in the deepest regions are 21.85 and 20.15 in the J - and K _ { S } -bands respectively in the Vega magnitude system .

The J - and K _ { S } -band galaxy counts in the AKARI NEP field are broadly in good agreement with those of other results in the literature , however we find some indication of a change in the galaxy number count slope at J \sim 19.5 and over the magnitude range 18.0 < K _ { S } < 19.5 .
We interpret this feature as a change in the dominant population at these magnitudes because we also find an associated change in the B - K _ { S } color distribution at these magnitudes where the number of blue samples in the magnitude range 18.5 < K _ { S } < 19.5 is significantly larger than that of K _ { S } < 17.5 .
