Seiichi Miyake


Seiichi Miyake was a Japanese engineer and inventor best known for his work called "tactile paving" to aid the visually impaired at traffic crossings. They were first introduced in a school for the blind in Okayama City in March 1967. In the years since, Miyake's system has been adopted around the world.

Inventing tactile bricks

In 1965, Seiichi Miyake used his own money to create tactile bricks, which have patterns of raised shapes on their surfaces that can be detected by touch. He invented the blocks to help a friend who was starting to have visual impairment. These patterns indicate different safety or hazard conditions, such as raised dots or blisters for "caution", or long parallel strips for "safe to move ahead". They were also used to identify the boundary between footpath and the road. There are generally two predominant types, namely, the bricks with dots and bricks with bars. The former alerts the visually impaired of danger while the bars provide directional cues. However, "the paths have been constructed inconsistently," in different times and places.
Two years later, on 18 March 1967, Okayama City was the first place to install this invention for visually impaired people. The bricks' bright color is visible to people with low vision and cognitive impairments.
Ten years later, thanks to its safety and navigation benefits, the use of tactile bricks became mandatory in the Japan National Railway. By 1985, it was mandated for broader use in Japan.

Honours

In 2010, the Okayama Prefectural Association for the Visually Impaired registered March 18 as the Day of the Tenji Block with the Japan Anniversary Association. A monument for the Tenji Block birthplace was unveiled at the Harojima intersection in Naka Ward with a theme song, "Shiawase no kiiroi michi".
On 18 March 2019, Google Doodle honoured him by creating a short animation of a person with a probing cane being moved over tactile bricks.
