I can only speak for ITE products per IEC 60950. Note that this
standard requires testing for safety at -10% and +6%, or 90V to
106V for Japan ITE rated at 100V only. Note that this must be
done for both 50Hz and 60Hz, both of which are used in Japan.
I am not aware of any stated 85V test requirement for Japan, and
would be surprised if long term 15% voltage drops were common in
Japan. As in any country, there can be momentary "brown outs"
where the voltage may briefly sag to even lower values.

Subject: Japan mains voltage
Hello,
As you probably know the mains voltage for Japan is 100V.
For safety we are testing up to - 10%: 90 V.
However for some situations in Japan , it seems you can even expect 85 V.
So we are planning to define a general rule that a product for Japan must
handle 85 V.
Is this low voltage rule known or common use in your company?
best regards,
