You can make it into Tokyo. You probably won't reach Tokyo before 7pm. And you'll need to leave Tokyo by 11am at the latest on the day of your flight.
You should, indeed, do everything possible to spend an extra lifetime in Tokyo.
What to do and where to stay are extensively discussed in other threads.
