Tokyo MNetters - can a tourist book a private antenatal scan?

[TokyoQn]

We’re coming to Japan on holiday in my second trimester. Everyone says flying will be fine but I wondered whether it was possible to book a quick reassurance scan in Tokyo, as it is in the UK. Is there anywhere that offers something along the lines of ‘Window to the Womb’?

I would think hard about what you'd do if it picked something up while you were away

Yes, that is a very good point to consider, thank you.
