A museum in Chichibu, Saitama Prefecture, has been drawing more visitors since its unique collection of more than 1,700 rocks resembling human faces, including Elvis Presley and the late Russian President Boris Yeltsin, gained online fame.

At Chichibu Chinsekikan (museum of rare rocks), a rock that looks like a man sporting a pompadour hairstyle, titled "Elvis Presley," and other rocks that simply look like crying faces or laughing faces because of cracks or patterns on their surface are on display.

Its current curator, Yoshiko Hayama, 67, said the rocks were collected by her father, Shoji Hayama, who opened the museum in 1990.
