A Gentle Hint of the Forest in Your Bath

The Hinoki Wood Ball in Onsen Box

Onsen Box was created to bring the quiet, restorative feeling of a Japanese hot spring into everyday life.

Beyond mineral water and bathing rituals, a true onsen experience is shaped by subtle elements—the air, the stillness, and the scent that gently surrounds you.

One of those elements is hinoki, Japanese cypress.

The Scent Closest to a Japanese Onsen

Step into a traditional onsen bathhouse, and there is often a moment when you pause and breathe more deeply.

That calm, clean aroma is often hinoki.

For centuries, hinoki has been used in Japanese bathhouses—for soaking tubs, floors, and wooden bath tools.
Its scent has become inseparable from the memory of Japanese hot springs.

In Onsen Box, the hinoki wood ball is included as a quiet companion to your bath, allowing the fragrance to blend naturally with warm water rather than overpower it.

From the Forests of Hakone and Odawara

The hinoki used for this wood ball comes from the forests of Hakone and Odawara, areas long associated with hot springs and mountain nature.

The wood is sourced from forest thinning—a practice essential for maintaining healthy, sustainable forests.　By giving this material a second life, the hinoki ball carries both the scent of the forest and a respect for nature.　Untreated and uncoated, it offers the wood in its most honest form.

Simple Ways to Enjoy

There is no single “correct” way to use the hinoki wood ball.

• Place it in warm bath water and enjoy the soft, natural aroma
• Hold it in your hand for gentle acupressure during bathing
• After your bath, leave it in a bathroom or entryway to enjoy the lingering scent

Let it become part of your own bathing rhythm.

The Beauty of Natural Wood

Because the hinoki ball is made from untreated natural wood, each piece has its own grain, knots, and subtle variations. Occasionally, natural resin may appear—this is harmless and a natural characteristic of hinoki.

If the scent fades over time, lightly sanding the surface can refresh both texture and aroma.

A Quiet Moment, Inspired by Onsen

The hinoki wood ball is not meant to stand out.

Instead, it supports the bath experience in a quiet way—
inviting you to slow down, breathe deeply, and reconnect with the present moment.

That gentle pause is at the heart of Japanese onsen culture.
And it is what Onsen Box hopes to bring into your home.
