A long, narrow island between two rivers in the middle of the city, carrying the city hall, a red-brick public hall from 1918, a rose garden and a run of museums. The island is free; the collections are not.
What it costs
The island, the promenades and the rose garden cost nothing. The museums on it are individually ticketed — there is no island-wide pass — and the Central Public Hall can be looked at freely from outside but has restricted access inside.
The Central Public Hall, the red-brick building from 1918 that everyone photographs, has a free exhibition room in its basement explaining the building and the merchant who paid for it. The main halls above are event spaces and are not generally open.
When to go
Late afternoon for the light along the water, or after dark when the public hall and the bridges are lit. The rose garden is at its best in late spring and again in autumn.
In winter the whole island carries an illumination that runs along the riverbanks and is one of the few genuinely free evening attractions in the centre.

Getting there
It runs east to west through the middle of the city between Umeda and the castle, and the most pleasant approach is on foot along the river from either end rather than by surfacing in the middle of it.
Two of the museums sit almost adjacent at the western end, which is the only stretch where the island works as a single visit rather than a walk.
If you only have an hour
Walk the north bank from the Naniwa bridge to the public hall, cross, and come back on the south side. It is flat, it is quiet, and it is the only part of central Osaka that feels unhurried.
What people get wrong
It is not a park, and people arrive expecting one. Nakanoshima is a working civic and financial district that happens to be on an island with gardens at one end. The pleasure of it is the architecture and the water, not green space.
