Can't you read chinese ?
They use simple kanji.
That's Chinese; for if its streaming. We have physical editions in China and France so far. Doubt they'd do a physical release on a streaming version. There is also the fact that there is yet any streaming outside of Japan.
Ah, well that's what I get for not reading carefully and just checking the images :P
And no, I can read neither Japanese nor Chinese. Both use Kanji so I simply mistook it for Japanese at a glance.
And yeah, I could imagine a physical box with a code for the streamed version. They already sell empty boxes so why not? But that wouldn't be the case in France though so that is an interesting additional piece of evidence
