You'll find an underground passage to reach the north side after exiting the ticket gates.
In the middle of the passage, there's a plastic bench. I tried sitting on it, and it was comfortable even for me, an adult. It's probably made of plastic, so it might not feel the sturdiest, but...
There are lights and surveillance cameras, so security is considered, but it's dimly lit at night, so I don't recommend resting there alone if you're a woman.
Around Takatori Station, there used to be a JR Takatori factory about 20 years ago. As a reminder, there are monuments of train wheels and explanatory panels in the underground passage, which are interesting to see.
