I am afraid not, Brother.
We have plenty of Jomon artifacts dating all the way back to 14,000 BC. But the most anyone's ever been able to grant them re. ocean travel is a skip across the Korea Straits from Kyushu Island.
Not exactly a cruise on the open sea.
With ten thousand years worth of artifacts, surely if they had sailed to Ecuador in 2500 BC, we'd have found some evidence other than a similarity in pottery.
Of course, that's just my opinion, and I'm inclined to be rather conservative in these areas, as you know.
What I'm thinking is that the pottery style could have accompanied some of the earliest migrants into the Americas via the Bering land bridge. We know there were very few people here at the time, we've not really found anything resembling a semi-permanent site that these people occupied, so it might not be surprising that we don't find much pottery until they settle down somewhere.
The Valdivia pottery might just be the first place we've been able to locate any of the earlier stuff.
You realize that the pottery at Valdivia is said to resemble the old and middle Jomon style?
Here's a piece of Middle Jomon Pottery:
Here's some of the Old Jomon style pottery:
Here's the original paper by Meggers, Evans and Estrada your link mentiones (it's in PDF format.)
Early Formative Period of Coastal Ecuador, The Valdivia and Machalilla Phases
Maybe I'm wrong, but the Ecuadorian stuff seems waaay more like the Old Jomon style. Bunch of pics in the PDF.
Probably there wasn't much known about the Jomon when Meggers first did her work in Ecuador.
Anyway, look here what I also found:
This semi-sedentary culture led to important population increases, so that the Jomon exhibit some of the highest densities known for foraging populations.. Genetic mapping studies by Cavalli-Sforza have shown a pattern of genetic expansion from the area of the Sea of Japan towards the rest of eastern Asia. This appears as the third most important genetic movement in Eastern Asia (after the "Great expansion" from the African continent, and a second expansion from the area of Northern Siberia), which suggests geographical expansion during the early Jomon period. These studies also suggest that the Jomon demographic expansion may have reached America along a path following the Pacific coast.
Source is the same as the Jomon pottery pictures.
