Why People Are Showering Less: Japan’s High-Tech Washing Machine for People

A new high-tech capsule from Japan may help explain why.

In many homes, showering has long ceased to be an everyday routine. A closer look shows that this is about more than convenience alone. As energy saving, skin health and futuristic washing capsules converge, our understanding of personal hygiene is beginning to shift fundamentally.

Showering less: a trend, a necessity or a healthier routine?

For years, having a shower every day was considered the norm. Anyone who did not was quickly seen as unclean. That perception is now gradually changing. Dermatologists are raising concerns, energy bills are climbing and water is becoming scarcer – while new technologies are simultaneously rethinking hygiene entirely.

Younger people in particular are questioning the old “shower every morning” routine. Many now use shower gel only every other day, while some do so even less frequently. Flannels, aluminium-free deodorants, dry shampoos and quick washes at the basin are being used instead.

“The body needs to be cleaned – but it does not necessarily need a full head-to-toe shower every day.”

People who shower less often usually have several reasons at once:

• Their skin becomes irritated by daily hot water and harsh surfactants
• Gas and electricity costs are making long showers a luxury
• Awareness of water use and resources is increasing
• Working from home reduces the social pressure to look “fresh” at all times

High-tech instead of a towel: the Japanese “washing machine for people”

Alongside this trend, a company in Osaka is developing a radically different approach: washing in what is essentially a washing machine for people. The technology has the futuristic name “Mirai Ningen Sentakuki”, broadly meaning “washing machine for the person of the future”.

Technically, it is an enclosed capsule in which a person sits. Inside, the body is washed in around 15 minutes and then dried immediately afterwards – without the person having to do anything themselves.

How the body capsule works in detail

The machine brings together several elements:

• Enclosed capsule: The user remains seated in a pod-like unit throughout the whole process.
• Microbubble technology: Extremely fine air-and-water bubbles surround the skin, lifting away dirt, sebum and dead skin cells.
• No scrubbing: The cleansing process is gentle enough that mechanical rubbing is virtually unnecessary.
• Drying system: Once washing is complete, an integrated drying module takes over, much like a tumble dryer – except it is designed for people.

The concept is intended to deliver maximum comfort while cleaning gently. It could be particularly beneficial for people with sensitive skin or restricted mobility.

AI in the bathroom: when the shower knows your pulse

The real innovation behind the Japanese invention is not washing alone, but its digital controls. The capsule is packed with sensors that record a range of bodily data.

These include, for example:

• Heart rate
