Probably not in English-speaking countries; Netflix is generally not interested in providing subtitled animation, they prefer dubs. However, it might be available in the rest of Europe.
If you would like it to be available in your area, please contact Netflix and tell them! I’m sure that the animation team would be willing to work something out. =)
I was gonna ask this!
Already recommended it to a load of people on an anime forum to watch it 😊
