Large Japanese charger with Manji or Swastika symbol

I fell in love with this incredible large Japanese charger as soon as I saw it and the use of the Manji symbol just made it all the better. This is the largest charger I have and it measures 18.5 inches across, 2.5 inches tall and weighs just 1 ounce shy of 8 pounds. It looks to me like it has some age to it but other than that I know very little about it. I would greatly appreciate any help in identifying the makers mark, the writing in red, age etc; but mainly just wanted to share it.
