"Twelve boats set out for the hunt, but they returned with no catch," a Taiji fisheries spokeswoman told AFP.
They will set sail again on Friday if the weather allows, she added.
The six-month season was due to start Tuesday.
In the annual hunt, people from the southwestern town corral hundreds of dolphins into a secluded bay and butcher them, turning the water crimson red.

Environmental campaigners visit the town every year to watch the gruesome event and authorities have boosted their presence to prevent any clashes between locals and activists.
