Flying from Tokyo to New York with a layover in Beijing for 22:50 hrs

If you arrive in Beijing at 10:05 and have an almost 23 hours' layover, you will need to catch the flight departing from Beijing at around 9am next morning, you will have no time to visit any site that morning. What's more, most of the sightseeing spots stop selling tickets at around 16:00-17:00, so you actually only have half day to visit the site. You may consider utilizing this period of time to visit the Great Wall only or have a city trip to visit the Tiananmen Square, Forbidden city, Temple of Heaven (or Summer Palace).
