Right now JR East company has halted the use of anonymous Suica cards, due to a shortage of semiconductors, you can still get two different types of cards if you are a tourist. You can register your information or you can receive this special tourist transportation cards.
Here is an article about why this is happening.
Currently, the measure is only with JR East, but I imagine that other companies will follow suit, since the semiconductors shortage is global. Some regional providers might have a surplus, though, since they don't have as many international visitors who purchase cards and never return them to be recycled. Then again, it is also why JR East has so much capital. The cards are issued for 500 JPY each and the amount of money left on them amounts to an interest-free loan to the transit company.
