I bought this for my 2000 LS400 which has the P0156 code.
But is this the right one?

no! what you listed is the upstream sensor (sensor 1). you need the downstream sensor (sensor 2).

P0156 = sensor 2, bank 2 is located on the passenger side after the cat.

you need:
Denso 234-4137

OMG I just ordered the wrong one (upstream).
So it already shipped so I ordered the downstream one too.

At least I can replace both the up and down at the same time...maybe I should hang on to the upstream one until one of them fails first...
