Clark Kimberling in his _TCCT_ [1, p. 75, Point X_54] writes it as KONITA
(without the s, that is), refering to John Rigby [2].

The name sounds to me rather Japanese.
Cf. other Japanese math/ans' names ending in -a:
Kakeya (of Kakeya Problem), Taniyama, Shimura (of the Taniyama-Shimura-Weil
C.), Ajima, Kariya (see below) etc.
Also, we know that Japanese mathematicians were strongly interested in
Triangle Geometry. Some names:
Ajima of the Ajima - Malfatti Points [1, p. 97]
Kemotu of Kemotu Point [1, p.268]
Kariya of the Lemoine - Boutin - Retali - Kariya Point [3, pp. 549 - 551]
So, probably Ko(s)nita of the Ko(s)nita Point is Japanese.
