Product Description

Replenish the tranquility of your space with this 300 ml (10.1 fl oz) refill for our “Scent of the Forest” diffusers, now available in a faint fragrance for those who appreciate subtle, whisper-like aromas. Designed to harmonize with our artisan-crafted diffuser vessels, this gentle refill continues your sensory journey into the Japanese forest. The lightweight bottle, measuring approximately 5 inches tall and 2.5 inches wide, complements the simplicity and elegance of your home.

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—diffusing softly in your space. Ideal for sensitive noses or for those who prefer a gentle olfactory backdrop, this version evokes the calming stillness of a forest glade, with green, woody, and herbal notes masterfully layered by Japanese fragrance artisans. Each whiff evokes a serene forest retreat, helping you unwind and rejuvenate in your own home.

Sustainable Refill, Timeless Ritual

This refill extends the life of your diffuser without the need to repurchase the entire set, optimizing both utility and sustainability. The 300 ml (10.1 fl oz) of fragrance oil offers up to three refills, depending on your vessel size and room conditions. The minimalist packaging embodies 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.

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.
