Outstanding cleaning power to remove dirt around the house quickly and easily
Hi-Home is a long-selling cleanser that has celebrated its 60th anniversary of production and sales. Since starting production in 1963, it has been made with an original manufacturing process that doesn't use potentially harmful substances such as synthetic surfactants, phosphates, fluorescent agents, colorants, bleaching agents, or fragrances. Today, Hi-Home enjoys widespread popularity in homes, schools, hospitals, hotels, and even among professional house cleaning experts.
Hi-Home effectively tackles various types of tough stains and dirt around the house, from grease on range hoods, dishes, and cooking utensils to water stains in bathrooms and washrooms, stains on the collars of children's sportswear, sports shoes, and even electronic appliances. Made from natural ingredients, it is safe for everyday use.

Tough on dirt yet gentle on your hands: Hi-Home and Clean Sponge
Hi-Home is made from siliceous sinter, a hot spring mineral deposit (yunohana in Japanese) that forms over a long period of time. Siliceous sinter contains a high proportion of soluble components, which, when mixed with soap, mostly turn into sodium silicate, a compound with cleaning properties. Additionally, its fine and soft particles make Hi-Home gentle on surfaces, effectively removing dirt without causing scratches while remaining safe and mild on the hands.
You can target dirt more effectively by using Hi-Home in combination with our Clean Sponge. The frame structure of the sponge makes it durable while giving it excellent foaming and quick drying, as well as resistance to water, oil, and chemicals.

A detergent specially made for grease stains: Oil Master
A product of the Hi-Home line, Oil Master is a detergent specifically designed for grease stains, with the following features:
- Easy Disposal After Cleaning
Unlike traditional grease cleaners that "remove oil with oil," Oil Master breaks down the grease (hexane) to eliminate stain. The wastewater containing the broken-down grease has a hexane value* reduced by more than 45%, so it can be disposed of as it is. Even when you have no access to drainage outlets, you can easily clean the dirty spot by simply spraying Oil Master directly and then wiping off.
*Hexane value: one of the indicators of oil content in wastewater.
- A Highly Safe Special Mineral as the Main Ingredient
Oil Master's main ingredient is a special mineral that meets the Environmental Quality Standards for Water Pollution, making it environmentally friendly.
- Designed to Be Gentle on the Environment and Hands
Free from surfactants and chemicals, Oil Master is gentle on both the environment and your hands and can be used with peace of mind.

We take environmental issues seriously.
Humans have been using natural detergents since the dawn of time. In Japan, people used to wash dishes with rice water or rice bran and even wash their faces with nightingale droppings—practices that are actually not so distant in the past. Hi-Home is a soap cleanser suitable for a wide range of uses that combines siliceous sinter, a hot spring mineral deposit known as yunohana in Japanese, with high-quality soap made from coconut oil. Environmental pollution caused by synthetic detergents has become a serious social issue. Since we began producing Hi-Home in 1963, we have been committed to creating eco-friendly, safe detergents made with an original manufacturing process that doesn't use potentially harmful substances such as synthetic surfactants, phosphates, fluorescent agents, colorants, bleaching agents, or fragrances. Today, our product enjoys widespread popularity in homes, schools, hospitals, hotels, and even among professional house cleaning experts.
