A Japanese research team has found that water believed to have existed on Mars 3.5 billion years ago was almost as salty as “Kyoto locals hating on foreign tourists”.

The team has said it succeeded in restoring the conditions for water that is believed to have existed on Gale Crater and found the levels of salt and minerals were nearly equal to a Kyotoite’s animosity towards gai-tourists.

The water was “pretty much as salty as a Kyotoite traveling into Kamogawa in peak tourism season,” said Kanazawa University associate professor Keisuke Fukuseki.

“We’ve never seen liquid as salty as this.”

The claim comes as Kyoto banned foreign tourists from taking photographs in public places this week and will be policing the new law by installing cameras to film tourists filming the streets.
