A flotilla of some 20 Japanese boats set out for the Senkaku (Chinese: Diaoyu) islands and is expected to anchor off them early on Sunday.
The politicians plan to commemorate Japanese dead in World War II, when Japan occupied eastern China.
But Japan's government has denied them permission to land on the islands.
China says the event will undermine its "territorial sovereignty" and this is the latest move in an escalating dispute over the islands.
