US President Trump when asked regarding US intervening in the yen, says US is intervening because US has a good relationship with Japan, and we're always there for Japan, adds US is getting financial benefit out of the arrangement

Remarks from a US president touching on intervention in the yen sit in rare territory, since currency operations are conventionally the province of Treasuries and central banks and White House commentary of this kind has historically been confined to broad dollar preferences rather than specific bilateral pairs. The phrasing here is ambiguous in the way such off-the-cuff remarks often are: it is unclear whether it refers to an actual standing arrangement, to past episodes of coordinated support, or is simply imprecise language, and episodes of this kind have tended to be walked back or clarified by Treasury officials before any operational conclusion can be drawn. The historically relevant precedent is that joint US-Japan currency action has been the exception rather than the rule, reserved for episodes of extreme one-way moves and conducted through official channels with explicit communiques, not ad hoc presidential comments. The reference to financial benefit is also non-standard framing and more consistent with a political characterisation of the relationship than with any described mechanism such as swap lines or coordinated sales. The follow-ons that matter are whether Treasury or the Japanese finance ministry confirm or deny any operational substance, and whether the remarks are repeated or refined, since a single unsupported comment has historically faded from the pair within the session while official confirmation would be a different event entirely.
