Mega Drive consoles in Japan
From Sega Retro
The Sega Mega Drive first debuted in Japan in October 1988.
Launch Mega Drives came in a different box than later models.
Mega Drive (with Sonic the Hedgehog)
Following discussions with their American arm, Sega decided to bundle the console with their flagship product, Sonic the Hedgehog.
Mega Drive 2
Unlike the west, the second model of the Sega Mega Drive in Japan opted for a title containing the number "2", rather than the roman numerals "II". This cost-reduced model is again identical to its international counterparts (bar the colour scheme), but features a power switch instead of a button.
