I found the official Sonic Adventure Japanese website.

And here it is, the official Sonic Adventure Japanese website (https://sonic.sega.jp/sonicadv/index.html), it's filled with images of the development and documentation on how the game was being worked at the time.

That´s awesome, I was really dissapointed as a kid when I tried to enter that website on the chao garden just to discover it was shut down.

funny how old websites like this just get forgotten but still stay online. like some old still standing temple or tomb no one has been to in years.

Yup! It’s still up! In fact, some parts of the original webpages are actually in the disc for the Dreamcast Sonic Adventure. Just pick the “Internet” option in the main menu to see a small bit of 90’s web goodness!


It sucks that so much of the Chao experience was locked to the online element though. It makes Chao raising a pain in the modern day on real hardware.
