City Hall lights up blue for World Stroke Day
Every year, Oct 29 is World Stroke Day, set by the World Stroke Organization. In Japan, the Japan Stroke Association leads awareness activities and marks October as Stroke Month.
To match the day, Kawasaki City will light the main City Hall building in Miyamoto-cho, Kawasaki Ward, in indigo blue. This is the symbol color of the World Stroke Organization, and monuments and buildings across Japan are lit in the same color. The list of places taking part nationwide is on the Japan Stroke Association website (https://www.jsa-web.org/citizen/4855.html ).
Stroke is Japan's fourth leading cause of death
A stroke happens when a blood vessel in the brain becomes blocked or suddenly bursts, disrupting blood flow in the brain. There are strokes caused by a blocked vessel (cerebral infarction) and by a burst vessel (cerebral hemorrhage and subarachnoid hemorrhage).
Stroke is the fourth most common cause of death in Japan. It is also the top cause for people needing the highest level of care (care level 5), and the second cause for care levels 4 and 3. Prevention matters, and if a stroke happens, it is important to see a specialist hospital as quickly as possible.
Videos and help on stroke
Videos from the Japan Stroke Association explain what a stroke is, how to prevent it, what to do when it happens, and where to get support after leaving hospital (in Japanese).
