Connecting flight international to international at Beijing Capital Airport

Hello, I will be arriving in PEK from YVR (Vancouver) at 3:30pm (15:30 hours) via Air China to connect to a flight to HND (Tokyo) which departs at 5:10pm (17:10 hours) via Air China and I feel like this time frame cuts it pretty close. Does this leave me enough time to get to my connecting flight without issues? Are there any tips on ensuring a smooth transition? Do we have to pick up our luggage or will t be transferred to our plane automatically? Any information will be very helpful! Thank you!
