If you have Apple care, it’s cheap to get fixed. One screen break is worth the extra bit for Apple care.
That said, I’ve used this shop below in Shinjuku a few times before I had Apple care.

But... looks like they can’t do X yet...
you weren't kidding... it's 280 US without apple care and $29.00 with apple care. Cheaper than a case, and screen protector.
But it is a hassle to go to my apple store and nearly over a week's wait to get an appointment..
