I think most, if not all, capsule hotels accept male guests only (for safety and liability reasons). You may want to look for so-called business hotels near Shin-Osaka Station.

There is a capsule hotel in Shin-Osaka Station, and, however, exclusive use of a man.
JR pass cannot use Sinkansen "Nozomi".
The Sinkansen which you can use,
The Sinkansen doing the first departure to Tokyo,
It is Sinkansen "Hikari-404".
It departs from Shin-Osaka at 6:08 .
I recommend Doubutsuen-mae for cheap hotels too. It's a grubby area and the hotels have shared bathrooms, but the prices can't be beat. You can take the Midosuji subway line directly to Shin-Osaka station to catch the Shinkansen.
I've stayed in this hotel several times. Loading...
It's a little more expensive than the other hotels in the area, but it's noticeably cleaner. It also felt safer.
