Japan region releases of SA1 and SA2

ソニックアドベンチャー2
So I learned recently, Japan is missing a bunch of Sega titles, but still try to offer the bundles on steam. For example Jet Set Radio isn't available, so if you buy "Dreamcast Collection" you're only getting SA1 and SA2 at a discounted price. Shenmue I & II isn't available, but the Shenmue bundle is. Buyers would just be getting Shenmue III at a discount price again.
To me, this whole situation has been invisible as the US seems to be the favored region. Steam is pretty good about leveraging price differential for less-fortunate regions. They also celebrate internationally regional sales like Golden Week and Lunar New Year.
The flipside is Japan has games region-locked to the West, like
Super Robot Wars V and
X.
