I will soon visit Tokyo, having visited before quite some years ago. During my first visit I intensively used the [metro tickets available for tourists](https://www.tokyometro.jp/en/ticket/travel/index.html), and I was wondering if these are still available. The reason I am not certain is that all information I can find about them still lists exactly the same prices as when I visited last, roughly 8 years ago, and it seems odd to me that there would have been no price increase. If they are still available, are they still sold at BicCamera stores?
