A map exhibition by college women introducing Jimbocho runs at Chiyoda Library (Kudanminami 1-2-1, ward office 9F) through October 27 — I dropped in.
Kyoritsu Women's University architecture/design graduates made it for a "Jimbocho revitalization" class — seven groups explored beyond used books.
Jimbocho Concierge Nav — mascot "Ponio" suggests routes by personality. Jimbocho Time Slip — twelve retro cafes in converted machiya. Subculture Jimbocho — back-street oddities without reaching Akihabara. Student Discount Heaven — literal student deals. Maps are copyable.
There were B-grade gourmet spots for athletic men too — my stomach said no; subculture made my brain scream. Can you accept a coed's recommendations?
Chiyoda Library — 5 min from Palaceside Building. Open daily 10:00; Mon–Fri to 22:00, Sat 19:00, Sun/holidays 17:00; closed 4th Sunday.
