Sustainably Designed for Minimal Waste

Packaged in an eco-conscious refill bottle, this 10.1 fl oz (300 ml) size replenishes your existing glass diffuser up to three times, depending on the vessel size and surrounding conditions. This refill format minimizes packaging waste and extends the home fragrance experience, all while aligning with the Japanese concept of mottainai.

To refill your diffuser, remove any remaining oil from the vessel, pour in the new fragrance using a funnel or directly from the bottle, and replace the reed sticks with fresh ones or reuse the absorbent ones. Allow 24–48 hours for the fragrance to diffuse fully, and for best results, position your diffuser in a draft-free area, rotating reeds weekly for consistent scent throw.

This refill not only extends the lifespan of your thoughtfully designed fragrance ritual but also brings aesthetic harmony to modern interiors or wabi-sabi-inspired spaces. It’s a meaningful gift for anyone seeking a mindful touch.

Made by Odai in Odai Town

"Odai" is a brand rooted in the forests of Odai Town, Mie Prefecture—an area recognized as a UNESCO Eco Park for its harmony with nature.

Using only 100% natural ingredients, Odai develops aromas and goods made entirely from trees grown in this pristine environment. Every branch and leaf is carefully handpicked by the local forestry association, ensuring sustainable and respectful harvesting.

The essential oils are then gently extracted using traditional steam distillation, a slow process that captures the pure, unaltered scent of the forest—no additives, no shortcuts, just nature at its finest.

FAQs

All you need to know about Odai Home Diffusers.

What makes Odai essential oil diffusers unique?

Odai diffusers are handcrafted using natural materials sourced directly from the forests of Odai Town, Mie Prefecture—a UNESCO Eco Park. Paired with 100% natural essential oils extracted from local trees, each diffuser reflects the purity, craftsmanship, and environmental harmony of the region.

Are natural diffusers safe to use around children or pets?

Yes, as long as you use 100% natural essential oils and follow safety guidelines. Always keep diffusers out of reach of children and pets. Avoid direct skin contact or ingestion.

How should I care for my diffuser?

Keep your diffuser in a cool, dry place, away from direct sunlight. If it’s made of wood, let it dry fully between uses and avoid washing it with water. You can switch scents, but it's best to dedicate each diffuser to one type of oil to preserve the aroma’s purity.

How are the essential oils and aromatic waters produced?

All essential oils and aromatic distilled waters are produced using a traditional steam distillation method, which gently extracts fragrance compounds without the use of chemicals or solvents. The raw materials—branches, leaves, and wood—are carefully selected and harvested by hand by the Miyagawa Forestry Association, based in Odai Town. This method preserves the purity and complexity of the natural forest aromas, resulting in high-quality, 100% natural scents sourced directly from one of Japan’s most pristine environments.

How long does the scent last when using the essential oil with a natural diffuser?

On average, the scent from the essential oil will gently diffuse for about 1.5 months when used with a natural, passive diffuser such as wood or unglazed ceramic. Longevity may vary depending on room temperature, ventilation, and the amount of oil applied, but regular use with a few drops at a time ensures a continuous, subtle aroma throughout the space.
