Warm, Refreshing Forest Scent

Product Description

Cryptomeria japonica essential oil is a 5 ml oil made in Japan from the leaves and branches of the Cryptomeria japonica tree. It is made with 100% natural ingredients and has a warm, refreshing scent reminiscent of a forest.

For room fragrance, add 1 to a few drops to an aroma lamp or aroma mist diffuser and follow the device's instruction manual. The oil can also be used in an aroma bath: no more than 5 drops for a full-body bath or no more than 3 drops for a half-body bath.

This essential oil may also be used as an ingredient for handmade cosmetics such as hand creams and fragrance sprays. The bottle contains 0.17 fl oz (5 ml), a small quantity suited to trying the scent in a diffuser or aroma bath.

Because the raw material is natural wood, the scent may vary slightly depending on collection timing and the condition of the tree. Store the bottle in a cool, dry place away from direct sunlight and keep it tightly sealed when not in use. Do not ingest the oil or allow it to contact the eyes.

Care & Safety

Please read the product label and follow the manufacturer’s instructions before use. These products are intended for home fragrance only. Natural ingredients, including essential oils, may cause irritation or allergic reactions.

Precautions for use

• Do not ingest or apply to the skin. Avoid contact with eyes, mouth, and mucous membranes. Never apply undiluted essential oils directly to the body.
• Begin with a small amount, following the recommended dosage, and use in a well-ventilated space. Stop use immediately if irritation, discomfort, or breathing difficulties occur.
• Keep away from open flames, heat, and ignition sources.
• If pregnant or breastfeeding, or if you have asthma, allergies, or fragrance sensitivities, seek advice from a healthcare professional before use. Seek appropriate professional advice before using around infants, young children, or pets.
• For sprays, use only on surfaces or fabrics specified on the label. Test an inconspicuous area first. Avoid spraying toward people, animals, food, or drinks.
• Place diffusers upright on a stable, protected surface. Oils and fragrance liquids may stain or damage furniture and other finishes.

Accidental contact

• Skin: Wash promptly with mild soap and plenty of running water. Seek medical advice if irritation develops or persists.
• Eyes: Do not rub. Rinse immediately with lukewarm running water for at least 15 minutes and contact a poison centre or healthcare professional promptly.
• Swallowed: Do not induce vomiting. Contact your local poison centre or seek urgent medical advice immediately, even if there are no symptoms. Keep the product container available.
• Breathing difficulty or a severe reaction: Stop exposure and seek emergency medical assistance.

Storage & product care

Keep out of reach of children and pets. Store upright in a cool, dry place away from direct sunlight and heat. Close bottles tightly after use, except while a diffuser is in use as directed.

Follow the expiry date and period-after-opening guidance on the product label. Natural variations in colour, scent, or sediment may occur in some formulations; refer to the manufacturer’s guidance rather than assuming all changes are harmless.

If an essential oil becomes difficult to dispense in cold weather, gently warm the closed bottle between your hands. Do not use a microwave, hot water, or direct heat.

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.
