Tokyo is an energetic, bustling metropolis. But take a few steps off the main streets, and it reveals a different side to its character. This time on Japanology Plus, we explore the backstreets and alleys of Japan's capital city. Satoshi Okamoto shows us secrets and shortcuts in Ginza. Akiko Shiihara explains how alleys have turned Yanaka into an unexpected tourist hotspot. And Hidekichi Mizuno tells us how he started his alleyway business career -- by selling tangerines on the street.

In Japan, sword fighting is a common feature of period dramas. But Japanese swords, katana, were more than weapons. They were used in rituals, and held as status symbols. Today, they're viewed as works of art. This time on Japanology Plus, our theme is swords. Our main guest is manga artist Kimiko Kamata, author of a katana-themed manga. She explains why the blades have attracted a new audience of young, female fans. And in Plus One, Matt Alt learns how to properly maintain a Japanese sword.
