11 years ago, we Japanese people got the Tohoku Earthquake on March 11, 2011. It also caused the great tsunami (tidal wave), fire disasters for several points. They say over 18,000 people were lost for them. And happened what we can't ignore in Fukushima, Tohoku areas. Nuclear meltdown went on at the Fukushima Dai-ichi Nuclear Power Plant. Some parts of Fukushima were specified as dangerous zones, many residents had to move away.
After the disasters, increased the persons who took care about their disaster prevention in East Japan. And some of them paid attention to Nightstar JP produced by Daisaku Shoji in Tokyo.
As the pictures show, Nightstar JP is a flashlight. What's special? you may ask. Nightstar JP needs no batteries, in fact. Then how does it work when we are out of light? Just shaking about 30 seconds, it works about 20 minutes. There is a magnet inside its cylindrical part. It moves from the point to another by your shaking. Then happens some magnetism, it charges. Needless to say, you must keep it away from Nightstar JP when it has a fair chance to break by magnetism.
