Create a private Japanese voice book for your child, recorded by the people they know best.
Add family names, pets, favorite foods, or words unique to your home. A parent can record each word in their own voice, and the child practices those personal cards in a simple family-only session. Custom words and recordings stay on the device and are not uploaded. The first 3 family words are free; Kotoba Pro removes the limit.
Kotoba also includes 304 illustrated Japanese words for ages 3-6. Meet Kota, the friendly Shiba Inu guide, tap any word to hear it, then practice with Quiz Mode or Listening Quiz.
Kota's Day is a four-chapter story path built just for Kotoba. Children listen to words in context as Kota gets ready in the morning, visits the park, enjoys snack time, and gets ready for bed. One chapter is free; Kotoba Pro unlocks the full day.
