In one district of downtown Tokyo, early-morning joggers, parents pushing strollers, and a couple of alpacas out for their daily constitutional walk break up the stillness of the streets. Before returning to their home at an indoor petting zoo, "Alpaca Land," Akane and Satsuki jog around streets past stores and temples while being led by their caretakers. They also cut grass in a pocket park and share crosswalks with the rare pedestrian. After a round of brushing and combing, the woolly natives of South America are ready for their day: spending time with visitors who pay 1,000 yen ($7) for 30 minutes petting them, hugging them and burying faces in their fleece. "The alpaca was so fluffy that when I put my face on its back, its fleece covered half of my face and it was so cute," said visitor Nana Ide. Manager Shinya Ide (no relation) says the secret to the 5-year-old alpacas' appeal is that looking at them is comforting, and petting them even more soothing.
