If you're looking for manga similar to Runningman, you might like these titles.
After a long summer day of construction work, a woman goes to the store to buy some potato chips.
A wordless journey into the contemporary Japanese psyche. It takes the not unfamiliar plot backdrop of a train ride and turns it into a psychological meditation on the vehicle's architecture and passengers (rather than focusing on the usual narrative-driven concerns such as destination, distance or landscape).
Who needs dialog when you're this cute? The beautiful (but unlucky) Momoko, the cool, collected Shibumi, and the refreshingly innocent Mayumi star in a "silent manga." No speeches, no dialog! Just pictures, sound effects, and three high school girls living their daily lives.
