A new high-tech capsule from Japan could explain why people are showering less

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

In plenty of homes, the shower is no longer a daily ritual. Look a little closer and it becomes clear there’s more going on than simple laziness. Caught between cutting energy use, protecting skin health and futuristic washing capsules, our idea of what “good” personal hygiene looks like is starting to shift.

Showering less: trend, stopgap or a healthier routine?

For years, showering every day was treated as the norm. If you didn’t, it was easy to be labelled as unclean. That assumption is now slowly changing. Dermatologists are issuing warnings, energy bills keep rising, water is becoming a scarcer resource - and, at the same time, new technologies are emerging that rethink hygiene from the ground up.

Younger people, in particular, are questioning the old routine of “a shower every morning”. Many now reach for shower gel only every other day, and some even less often. In its place come flannels, aluminium-free deodorants, dry shampoos, or quick wash-ups at the sink.

"The body needs cleaning - but not necessarily a full head-to-toe shower every single day."

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

• Skin becomes irritated by daily hot water and harsh surfactants
• Gas and electricity prices turn long showers into a luxury
• Awareness of water use and finite resources is growing
• Working from home reduces the social pressure to look “fresh” at all times

High-tech not towels: Japan’s “washing machine for humans”

Running alongside this shift, a company based in Osaka is pursuing a radically different idea: washing in something like a human washing machine. The concept carries the futuristic name “Mirai Ningen Sentakuki”, which roughly translates as “washing machine for the human of the future”.

In practical terms, it’s a sealed capsule that a person sits inside. In around 15 minutes, the body is washed and then immediately dried afterwards - without the user needing to do anything themselves.

How the body capsule works, step by step

The system brings together several elements:

• Sealed capsule: the user remains seated in a pod-like unit for the entire process.
• Microbubble technology: extremely fine air-and-water bubbles surround the skin and lift away dirt, sebum and dead skin cells.
• No scrubbing: the cleansing is designed to be so gentle that mechanical rubbing is largely unnecessary.
• Drying system: once washing is finished, an integrated drying module takes over, similar to a tumble dryer - but for people.

The thinking behind it is straightforward: maximum convenience with a cleansing process that’s kinder to the skin. Anyone with sensitive skin - or with limited mobility - could stand to benefit most.

AI in the bathroom: when the shower knows your pulse

The real twist in the Japanese invention isn’t only the washing itself, but how it’s digitally controlled. The capsule is packed with sensors that record a range of bodily data.

These include, for example:

• Pulse rate
