Japanese clean and tidy decluttering guru Marie Kondo who became world famous for popularising throwing things away, has opened an online store selling homeware and fashion.

If it all sounds too ironic and as you rub your hands in glee for a major takedown, hold your horses.

Her online store's stuff are quite prohibitively expensive, so mere mortals might not be able to afford them anyways.

Kondo, who is also an author, has added a collection of more than 100 items that "spark joy" to her KonMari website.

They are, in her own words, things she would use in everyday life.

A dustpan and broom set is US$34.

A medium sized container is US$40.

A scented candle is US$86.

Not about encouraging consumerism

Her online store opened on Monday, Nov. 17.

It comes a few months after Kondo announced a partnership with Japanese e-commerce giant Rakuten.

It appears to be targeted at her newfound American fan base, who are kings and queens of credit-card maximising consumerism.

Kondo said in an interview with the Wall Street Journal that she is not trying to encourage consumerism.

The idea for a store came out of reader questions about what items she likes to use.

She said: "What's most important to me is that you surround yourself with items that spark joy."

"If the bowl that you're using currently sparks joy for you, I don't encourage replacing it at all."

Kondo said her tidying method "isn't about getting rid of things", in a letter posted on the site.

"It's about heightening your sensitivity to what brings you joy."

"Once you've completed your tidying, there is room to welcome meaningful objects, people and experiences into your life."

But if everything in life cost as much as what Marie Kondo sells them, your homes will also be uncluttered -- because you won't be buying anything to begin with.

Kondo started out writing books on organising homes.

They sold millions of copies.

She then did a spin-off series for Netflix.
