Our Story
HIKARI is a rhythm made visible.
HIKARI was developed jointly by respiratory physicians and dentists at Osaka Medical and Pharmaceutical University. Drawing on more than ten years of clinical experience with a variety of oral training appliances, the team has built the difficulties that clinicians and children meet in use into the design, one by one. From material selection and prototyping to clinical validation, it was created under the supervision of Japanese experts.
The name HIKARI
“HIKARI” is Japanese for “light” — a light of hope guiding children toward healthy days.
Rhythm
The coordination of the tongue, the muscles around the mouth and breathing is part of the natural rhythm of daily life. HIKARI aims to help children find that rhythm again every day.
Healthy bite habits
Building a steady bite posture through simple daily repetition.
Steady breathing pattern
Practising nasal breathing during quiet times — reading, homework, before bed.
Support for growing years
A gentle fit that growing children can keep up with.
For parents
Anything about your child's
breathing on your mind?
Habits like mouth breathing or tongue position are easy to miss day to day. Thinking of your child's usual routine, tick the items that apply.
If these habits last a long time, they may affect tooth alignment, bite, sleep and more (how much varies from child to child). Learn more →
How to wear
A daily wearing rhythm
Get used to it step by step, with guidance from your dentist or doctor.
Wear for 1–2 hours in a row
Best during quiet times — reading, homework or relaxing. Let the lips gently close around the trainer.
Sleep with it all night
The goal is to keep it in until morning. If the mouth opens a little during sleep, that's fine as long as the trainer stays in.
Take it slowly
It may feel unfamiliar at first. Add a little more time each day and it will start to feel natural.
While wearing
- Close the mouth naturally and bite lightly
- No clenching or chewing
- No talking while it's in

Line-up
Three types
Your dentist or doctor selects the type that suits the mouth and stage.
SOFT ソフト
A soft entry-level type that is easy to wear, even for first-timers. Typically for the mixed-dentition years (about ages 7–12).
CORE コア
The next step once SOFT feels familiar — a slightly firmer material than SOFT for continued training.
FORM フォーム
The same firmness as CORE. The next step after CORE, switched to at the clinician’s discretion.
