Bath Roman: Japanese Bath Salts Guide


There are oodles of Japanese bath salt brands that you can use at home, but one of the most well-known and loved within the country is Bath Roman (バスロマン).

Who makes Bath Roman Bath Salts?

Bath Roman Bath Salts are the flagship brand of Earth Chemical. They can be found on the shelf of practically every drugstore in Japan and have been in production since 1964.

What are the ingredients?

The bath salts are composed of sodium, minerals and other ingredients. Some contain extracts from Japanese onsens and have a higher proportion of natural ingredients. Each product is different, so I recommend selecting a product below for full ingredient lists.

What are the health benefits?

Japanese bath salts are revered for their medicinal qualities and for promoting blood circulation. Roman Bath claim that their products can help with recovery from pretty much everything; fatigue, colds, stiff neck, lower back pain, neuralgia, rheumatism, hemorrhoids, heat rash, soreness, acne, eczema, fever and more.

In addition, bath salts are loved for their relaxation properties too! These salts release soothing fragrances in the bathroom and change your bath water; softening the water, keeping in the heat and altering the color. They also help to rejuvenate and moisturize skin, making them perfect for a little self care.

How to use Bath Roman Bath Salts

Fill up your bathtub with warm water. The packaging on this range includes a handy measuring cup on the underside of the lid. Measure out one scoop of powder and add it to your bath. Mix the powder around until it dissolves, before immersing yourself in the tub. Soak for at least 20 minutes to feel the full effects.

How many baths can I take with one package?

Each package contains around 600 grams of powder and the measuring cup holds about 20 grams; giving you around 30 baths per package. If you have a larger bath, scoop around 30 grams – though a surprisingly small amount of powder goes a long way!

  1. Hello, I love this website! Do you have a recommendation for bath salts with no artificial dyes? I loved the tabino yado milky packs, but I’m kind of put off by the bright colors.

    1. Hi Amani, thanks so much for your comment! Apologies for the delay, I’ve been away for a little while. So glad you loved the Tabi No Yado bath salts, though some of the colors are rather bright indeed! For something without dyes, you might have more luck with extracted bath salts (or yunohana), such as the ones from Okuhida mentioned in this article here. Best of luck!
