Oh. You are clicking "Stop by Tamatown" or "Welcome to Music City", no?
You need to scroll to the bottom of the Bandai website, and there will be a small tab. Click on it, and the previous Tamatowns wil roll out. Choose the one you want to go to.
There is only a TamaTown For v4. Always Go to the v4 tamagotchi town for a V4.5. I should know because I have a v4.5 and I always use the v4 website. I just google. The website is https://v4.tamatown.com/tamaok.html. Hope I helped! (im kinda new here)btw v4 Website has awesome music lol :furawatchi:
