Won' t say it ' s acceptable to say who ' s staying .
But if it ' s history and with social media being so pervasive , well ..
Meaning Aman has always been rather discreet but these days along with new HQ management / new owners somewhat involved , much is public knowledge . If they say any thing , it ' s probably already in the news somewhere like Facebook, Twitter , etc which most have these days ( not me )
Like after Aman Tokyo ' s official opening , some guests are descending on Amano'i in the next few days / week .. If any of you reading this are here too , it will be interesting

, but being a widespread property , you may not see anyone anyway , perhaps at the restaurant

Perhaps you are already in Tokyo .. ainternational ??
