Product Description

Replenish the tranquility of your space with this 300 ml (10.1 fl oz) refill of our “Scent of the Forest” diffusers, now in a faint fragrance type for those who appreciate subtle, whisper-like aromas. Designed to harmonize with our artisan-crafted diffuser vessels, this gentle refill offers a delicate continuation of your sensory journey into the Japanese forest.

Whisper-Soft Fragrance, Inspired by Nature

The faint fragrance variant captures the ethereal quality of Kuromoji—a rare, aromatic shrub native to the Japanese mountains—while diffusing more subtly in your space. Ideal for those sensitive to scent or who prefer a gentle olfactory background, this version still evokes the calming stillness of a forest glade, with green, woody, and herbal notes carefully layered by Japanese fragrance artisans.

Sustainable Refill, Timeless Ritual

This refill allows you to extend the life of your diffuser without needing to repurchase the entire set. With 300 ml (10.1 fl oz) of fragrance oil, it offers up to three refills depending on vessel size and room conditions. The minimalist bottle supports conscious living while aligning with the Japanese aesthetic of simplicity and longevity.

How to Use

  1. Ensure your diffuser vessel is clean and free of old oil.

  2. Pour the refill slowly into your diffuser.

  3. Insert fresh reeds (or reuse if in good condition).

  4. Allow 24–48 hours for the faint fragrance to diffuse gently.

Place in intimate spaces like reading nooks, bedrooms, or tea corners where subtle scent enhances rather than dominates.

・The natural pigment from the branches may tint the fragrance water yellow or brown over time. This is a normal occurrence and does not affect the quality or performance of the product.

・Keep out of reach of children.
・If the liquid comes into contact with your skin, rinse immediately with cool or lukewarm water.

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.
