3. Reason
Firstly, it's used for fast/forms/text/text-font-height-mismatch.html.
Noto CJK 1.004 or later has unique metrics.  If we request font-size:16px,
resultant FontMetrics::height() is 24.  The imported font is helpful to test
such cases.  See crbug.com/519331 for the details.
Secondly, it's used in fast/ruby/ruby-position-modern-japanese-fonts.html to
test Ruby positioning.
Last, it's used blink's ShapeResultBloberizerTest.SupplementaryMultiRunNG
unit test (from blink_platform_unittests test suite).

To combine required glyphs for those two tests, use this command to generate the
subsetted font (generated from Version 1.004 of the font):
$ pyftsubset NotoSansCJKjp-Regular.otf\
   --text="いうかきくしじせちってにゃやゅょよわん㘵和天定弱強折晴洋焼肉衷過雨食〫𠜎𠜱𠝹𠱓𠱸𠲖𠳏𠳕"\
   --output-file=NotoSansCJKjp-Regular-subset.otf
