Editors at
AllMusic rated this album 4 out of 5 stars, with critic Tim Sendra writing that El Perro del Mar "wraps her brightly melancholy melodies in a jangling, worldly layer of sound that includes African rhythms, Middle Eastern drums, Asian woodwinds and strings, and rumbling bass" that results in "a stunning upgrade, and
KoKoro stands as one of the best works of her already pretty great career". At
Clash Music, Lois Browne called this an "elegant record which serves up something far from the norm" and gave it an 8 out of 10 for being "unusual, refreshing and vulnerable". Writing for

No Ripcords Juan Edgardo Rodríguez gave this work a 7 out of 10, writing that "beauty and elegance is always at the core of every El Perro del Mar release" and praised Sarah Assbring's for "utiliz[ing] an assortment of Asian and Middle Eastern instrumentation that provides a colorful and enlightening view to the album’s self-reflective musical excursions".

Pitchfork scored this release 7.1 out of 10 and critic Bejamin Scheim praised Assbring's ability to take "global influences [to] bring her to bright new places with inspiring albeit uneven results", criticizing that the music is "drawing from these ethnocultural traditions without a sense of clear rhyme or reason" but continuing that "Assbring’s knack for creating well-written, catchy melodies carries the record it even in its slightest moments". At
