Paris is so filthy that Japanese tour guides have started cleaning the streets themselves.

A group of nine guides, funded by the Paris Tourism Association, dispersed throughout the City of Lights Sunday to begin their cleaning mission in hopes of bringing more Japanese visitors to town.

Their first stop was the Trocadéro gardens near the Eiffel Tower, which they spruced up by planting cherry trees.

“They say they want to make the city cleaner for their own people, who have very high standards,” a Paris City Hall spokesman told the Mirror.

“But in recent years, Paris has actually become one of the cleanest cities in the world,” he insisted.

Paris is currently the fifth most popular place for Japanese tourists to visit — the US ranks No. 1 with 1.8 million visitors — with about 600,000 people going each year.

Paris Mayor Anne Hidalgo is trying to drum up tourism following the widespread terror attacks last November that left 130 dead.
