Shinkenger has some.
1. They go by a samurai lord and vassal heirarchy, thus the reason Hikoma, Ryunosuke, and Kotoha addresses Takeru as tono or tonosama despite being 2009.
2. Their suits are designed to resemble the gi and hakama, traditional Japanese attires.
3. When they go super, the additional attire is a jinbaori, another traditional garb of Japan.
4. Inroumaru is modeled after an inrou, a small carrying case that was made famous by the Mito Komon dramas(fun fact, Oh Blue/Yuji's actor Masashi Gohda of Ohranger fame, who played the first Shinken Red Retsudo Shiba, is also known for being part of this series of dramas)
5. The cockpit of the origamis resemble a rakugo stage. Rakugo is in Layman's terms a traditional Japanese spoken word/comedy show.
6. Shinken Red's personal weapon the Rekkadaizanto's blade surface has etch art of what is most likely Mt. Fuji erupting.

1. The cockpit seat of Shurikenjin resembles a traditional style Japanese litter typically seen during ceremonies and festivals.
