Customers pay around 1000 yen (NZ$13.60) to spend up to an hour with the 20 or 30 hedgehogs of varying breeds, with crowds of enthusiastic punters lining up for a chance to hang out with the prickly critters.
The café's Facebook page also shows a friendly yellow and black lizard who appears to reside alongside the hedgehogs.
Cafe worker Mizuki Murata - who works in a rabbit café in the same building - told the Guardian they hoped to improve the reputation of the animals.
"We wanted to show people the charm of hedgehogs, which give the impression of being hard to handle. We wanted to get rid of that image by letting people touch them," she said.
"The cutest thing about hedgehogs is getting them to finally open up and show you their face."
Japan is well known for its animal-themed eateries - but the traditional cat or dog café is starting to look a bit tame when you've got owls, goats and now, hedgehogs.
