Tenji blocks (点字ブロック) - small raised shapes in the pavement to assist visually impaired people in crossing the road - were first installed near the Okayama School for the Blind in Japan on March 18th, 1967.
Designed by Seiichi Miyake (三宅精一), the innovation gained traction in urban areas like Tokyo and Osaka, gradually spreading nationwide, particularly in bustling cities where safety for visually impaired individuals was paramount. But Miyake died before witnessing the global implementation of his invention.
