Yunohana Agent
YuNoHaNa bathing agent brings the mineral-rich water of Beppu, Japan's onsen capital, into a home tub. The powder dissolves into warm bathwater and turns it cloudy white, the same look and feel as a natural hot spring, without a trip to Japan. Sizes run from a 60g trial sachet through 1000g tubs, plus set-of-two and set-of-three bundles for anyone who wants a full month of soaks. Add a scoop before you get in, stir once, and let the mineral warmth do the rest.
Buying guide
How to use YuNoHaNa bathing agent
YuNoHaNa is a Japanese bathing agent (入浴剤) made from the mineral deposits of Beppu, one of Japan's largest onsen regions. A spoonful stirred into a full tub recreates the milky white water and warm, mineral-heavy feel of a natural hot spring at home. This collection covers small trial packs, everyday tubs, and multi-pack sets so you can pick a size that matches how often you plan to soak.
What is a YuNoHaNa bathing agent
YuNoHaNa bathing agent is a mineral bath powder, not a soap or a scrub. You add it directly to bathwater, where it dissolves and clouds the water white, the signature look of a Beppu hot spring. It is meant to sit in the tub with you, not be rinsed off first.
Why Beppu, Japan
Beppu is one of Japan's biggest onsen towns, known for hot springs with a naturally high mineral content. YuNoHaNa packages that same mineral profile as a shelf-stable powder, so the mineral soak travels with the product instead of requiring a trip to a hot spring.
How to use it in the tub
Run a full tub of warm water, add the recommended scoop of powder for your tub size, and stir until the water turns cloudy. Soak as you normally would. There is no separate rinse step required, though a quick shower afterward is fine if you prefer.
Choosing a size
This collection runs from a 60g trial pouch up to an 800g and 1000g tub for regular use, plus a 250g and 300g to 400g mid-size option. If you only want to try one or two baths, start with the smallest pack; if bathing agent is part of your weekly routine, the larger tubs work out to more soaks per package.
Set-of-two and set-of-three bundles
Several listings bundle multiple bags together, including a set of three 250g packs and a set of two 300g packs, along with a 1000g twin-pack bundled with a Montdolbinu item. Bundles are the better value if you already know YuNoHaNa is one you will keep buying.
What to expect from the water
Expect the bathwater to turn a soft milky white as the powder dissolves, with a mild mineral scent rather than a strong perfume. This is the intended effect of the mineral content, not a sign the product has gone off.
Who this collection suits
YuNoHaNa bathing agent suits anyone who wants a warmer, more mineral-forward soak, especially in cold months, or anyone curious about the Beppu onsen experience without traveling to Japan. It works as an everyday bath addition rather than an occasional treatment.
Storing the powder
Keep the pouch or tub sealed and in a dry spot away from the bathroom's direct steam and humidity, since a bath powder can clump if it absorbs moisture between uses.
Before you soak
As with any bath product, do a small patch test on your skin first if you have sensitive skin or a known reaction to mineral or bath products, and stop use if irritation shows up.

FAQ
Frequently asked questions
How do I use YuNoHaNa bathing agent?
Run a warm bath, add the powder for your tub size, and stir until it dissolves and the water clouds. Soak as you normally would; no separate rinse step is required first.
Why does the bathwater turn cloudy white?
The milky color comes from the mineral content dissolving into the water, the same effect you get in a natural Beppu hot spring. It is expected and not a sign anything is wrong with the powder.
Which YuNoHaNa bathing agent size should I try first?
The 60g pack is sized for one or two trial baths of the Beppu mineral powder. The 250g, 300g, and 400g options suit occasional use, and the 800g and 1000g tubs are for people who bathe with it regularly.
What comes in the set-of-two and set-of-three bundles?
The set-of-three is three 250g packs bundled together, and the set-of-two is two 300g packs. Both are the same bathing agent as the single packs, just sold as a multi-pack.
What is included with the 1000g bathing agent plus Montdolbinu bundle?
One 1000g bathing agent listing ships as a bundle that includes a Montdolbinu item alongside the two bathing agent packs. Check that listing's product page for the exact bundle contents before ordering.
How should I store the bathing agent between uses?
Keep the pouch or tub sealed and away from the bathroom's steam and humidity. A bath powder can clump if it picks up moisture between soaks.
Is YuNoHaNa bathing agent safe for sensitive skin?
Most people tolerate it well, but as with any bath product, do a small patch test first if you have sensitive skin or a history of reacting to mineral bath products, and stop use if you notice irritation.
Is the 1000g tub better value than the smaller packs?
Per gram, the larger 800g and 1000g tubs work out to more baths for the price than the 60g trial pack, so they suit anyone who already knows they will use it regularly. The smaller sizes are better for trying it out first.
