Tokyo is not a lively city for early birds on weekdays. Still less on weekends... I guess you could head to Shibuya and watch the late night revellers going home. On the other side of town,you can expect to be the only living boy in Marunouchi.
My recommendation would be to head to an onsen that's open 24/7 - soak in a bath and relax in the early hours. Then head somewhere for breakfast / brunch:
