Japanese Flower Stamp Hand Soap: MyKirei- How $18 Soap Became a Viral Sensation


Back in 2020, we needed all the joy we could get. So a company in Japan called MyKirei by KAO came out with their flower stamp hand soap (the timing happened to be by accident, but 2020 turns out to be the perfect year).  

This flower foam hand wash quickly went viral on the social media platform Tik Tok. Who doesn’t love a soap that provides a perfectly shaped foam flower with each pump- using an innovative dispenser system. 

Here is a picture highlighting the dispenser and what you press your hand onto:

The amount of soap that comes out is just enough to make the beautiful flower and no more. So it is kid-friendly with portion control.

Even though the soap costs $18 each, it quickly sold out on Amazon.com and other retailers. 

The soap itself is combined with Japanese yuzu fruit extract. This extract helps to brighten skin and is high in Vitamin C. It also uses rice water to help hydrate your skin no matter how many times you need a burst of joy seeing and smelling the foaming flower.

Plus, it has the standard germ-fighting powers of traditional soap to keep you healthy and hands clean. 

Vitamin C, rice water, kills bacteria, and produces a fragrant and awesome-looking flower… sounds pretty cool. Not only will this flower-shaped soap help you, but washing your hands properly will also help the spread of viruses. So you are helping to keep those around you healthy as well.  

Additionally, MyKirei by KAO soap is refillable (refilling soap saves 86% of plastic waste in landfills, according to the label on the bottle). So the expensive soap dispenser doesn’t go to waste.

Providing hundreds of bursts of joy and being easier on the environment.

Here is a quick video showing the process in action:

Product Details

Yuzu Flower Foam Hand Wash

Mykeri soap is luxurious and richly textured foaming flower stamp hand wash that is gentle but still kills bacteria. It is made with rice water and Japanese Yuzu fruit extract rich in Vitamin C. 

With each pump, the dispenser provides just the right amount of soap to create a foaming flower shaped like the Japanese Yuzu flower.

Packaged and designed for people of all abilities and ages.

How to Use

To use the soap, simply push the palm of your hand on the top of the pump and press down. This will dispense the foam onto your hand in the shape of a flower.  

You would think there would be lots of soap left after dispensing, but it is surprisingly effective. So, not much soap remains on the top of the dispenser after the flower is distributed.

Then, work the Yuzu-shaped flowering soap into a lather for at least 20 seconds and rinse with water. 

Each bottle contains enough soap for around 250 uses.

Update After Four Months of Use

Okay, so after four months of using this soap. It is still awesome! It works well and is still a joy to use. Although, the flower shape had started not to be as crisp as when it was new. Here is a picture (not terrible, but notable):
