From my cursory research these guys look legit. They make all of the OEM Honda HGs and they are owned by NOK out of Tokyo.
NOK makes many oil seals for the front axles/trannys/xfers for Toyota including LCs.
At this point the Toyota supply chain is so deep it would be tough to figure out who made what.
For example, 1HZ blocks are made by Toyota Industries, with timing cover and water pump from Aisin, with sensors from Denso, with crankshaft and rear main seals from NOK, with main bearings from Koyo, with pistons from Toyota Industries, etc., etc., etc.
Regardless of where you get your junk from, just makes sure it is quality. That would be my first and foremost criterion.
