stretches for several hundred kilometers. Firstly, the Japurá receives a long bifurcation from the Solimões itself and then drains into it through a main mouth located opposite the city of Tefé. However, a secondary branch, the Paraná Copea, continues its winding course until it rejoins the Solimões River 300 km downstream. This multiple confluence (resembling a very elongated delta) complicates the measurement of the length of the Caquetá-Japurá, which varies, depending on the method used, from 2200 to 2800 km, especially because the boundaries between the basins of other tributaries and sub-tributaries of the Amazon system are unclear in this flat, flooded, and swampy area. Some tributaries of the Japurá River originate very close to the Solimões River (Auati Paraná River), and some tributaries of the Negro River arise near the Japurá (Uneiuxi, Cuiuni, and Unini rivers), with connections and bifurcations between them during flood seasons.

It was initially supposed to have eight mouths, but colonial administrator Francisco Xavier Ribeiro Sampaio, in the historic report of his voyage of 1774, determined that there was but one real mouth, and that the supposed others are all

In 1864–1868, the
Brazilian government made a somewhat careful examination of the Brazilian part of the river, as far up as the rapid of Cupati. Several very easy and almost complete water routes exist between the Japurá and Negro across the low, flat intervening country. The Baron of Marajó wrote
535:
The Caquetá-Japurá is a "white water" river, which, like all rivers descending from the Andes, carries a significant alluvial load that it partly deposits when joining the Solimões (Amazon) River on its left bank. This is why the accumulated sediments on the banks have shaped a complex mouth that

In its lower course, it is joined by the Auati Paraná and Mirim Pirajuana rivers (the latter is sometimes considered a secondary branch, or a dead or backwater of the river).

English lieutenant Henry Lister Maw, Casement noted that these slave raids had been continued by Brazilian and Portuguese men. The territory of the Peruvian Amazon Company extended between the Putumayo and Japurá Rivers during the rubber boom.
