Best Japanese Bonus tracks

[BigTony]

for those unfamiliar a lot of musicians will have region exclusive bonus tracks this isn't an exclusively Japanese thing but they seem to do it the most in japan.
my favorite is Nice And Spicy on the Jamiroquai album Automaton

 

[Sir Auriel of Lionel]

Japan gets these exclusives or bonuses to encourage the domestic market to buy domestic releases that cheaper imports (which they were cheaper in some cases at the time and region locking wasn't a thing) with cassettes and CDs (I think?) My fav came from an ad.
