Masahiro does fantastic, professional shiatsu.
It's great for tight muscles or back pain.
He's great at finding the trouble spots even if you don't tell him and focusing on those areas.
I've been to him many times and have never been disappointed, except that I wish I had done 90 minutes instead of 60 minutes.
Not a fancy spa with bells and whistles, but absolutely gets the job done better than most spas.
