Perhaps inspired by the Mega Man 9 NES cart press kits, Capcom Japan packaged Mega Man 10 treats in mock Famicom boxes.
There are two types of Rockmanjo: a Rockman kind with shiroan and a Rockman 10 type with koshian. Both of these are bean paste filled sweets with Mega Man characters on the wrapper. You get six in a 630 yen ($7) box. If you’re lucky you’ll get a 1up like the bottom right piece.
Since Mega Man 10 is a downloadable game, this box is the only Mega Man 10 “package art” Capcom made for Japan.
