"You won't get wet under the elevated tracks"
You can access Namba Hatch at Minato-machi River Place from Exit 26-A of Namba Station.

From Exit 26-A, object benches extend to the underside of the Hanshin Expressway.
You can rest here, sheltered from rain and direct sunlight. While there's a lot of traffic, it's a good place to meet up for Namba Hatch.
So, why not consider using this area as a resting spot around JR Namba Station?
