Should we adopt the regulations of Japan for purchasing a gun?

Hawaii has somewhat similar regs. It seems to me though that the penalties for violating these laws should be much more severe than they are now in the USA in order to mitigate the impulsive and/or meditated urges to be reckless and murderous, especially in the area of safe secure storage and the accountability of such firearms should they be used to commit crimes, including having children gaining access to the firearms of their parents/guardians due to negligence. Severe mandatory sentencing laws for gun related offenses would be good start. As things are what with the firearms industries having a firm grip on most of our Republican legislators and the SCOTUS, much could be done should this bond among them be broken.
