古今 Nihonbashi (Kokon) is a long-established traditional bento and lunch restaurant near the Bakurocho intersection in Nihonbashi. Famous for its beautifully crafted three-tiered bento box (三段重), it draws loyal regulars and curious visitors alike. The cozy shop opens only for weekday lunch (11:30 AM–1:30 PM), with a small dine-in area where guests can enjoy yakitori, tsukune, and seasonal bento in a historic, unhurried atmosphere. An English-speaking staff member is available to help international guests. A hidden gem for a proper Tokyo lunch.
