Hi Jacelynn,
I'm happy for you and a little envious! What are your interests? I would try to dig into those and visit related locations / interview people etc.
For me, some of the most interesting themes and time periods are related to Japan's interaction with the outside world:
Bakumatsu Yae no Sakura and Atsu Hime for example, have segments at the end of episodes showing real life, modern day locations
Renaissance Culture and Japan’s Christian Century (1550–1650) here's a website with many interesting lectures the YouTube channel has many more videos in Japanese
Japanese - Korean relations: for example The Zainichi Korean Experience or The North Korean Bubble
