Meet Our Doctor
Listening for your baby's otonoha —
for a calm and peaceful pregnancy.
In a hospital exam room, you may feel tense, or find that limited consultation time leaves you thinking: I wish I could have watched my baby a little longer, or I never got to ask my questions.
As an obstetrician-gynecologist, I have been involved in many deliveries both in Japan and overseas. Through that experience, I came to wish, deeply, to offer families a more relaxed and personal setting in which everyone can share the joy of their baby's growth together.
Sharing your baby's heartbeat — their otonoha — in the most comforting private space of all: your own home. I will do my utmost to make these irreplaceable moments deepen your family's bond and become a source of great hope for the parenting journey ahead.
