- Acting for Two: Ultraman Ginga and Dark Lugiel are voiced by Tomokazu Sugita. Granted, that they were actually Literal Split Personality and/or Enemy Without.
- Author Phobia: Masayuki Goto based Dark Lugiel's cross-shaped eyes on a clown's makeup, due to his fear of clowns.
- No Budget: As the starting point of a series of New Generation Ultras, Ginga went out so badly in budget that the setting itself is simply Furuboshi Elementary School with nowhere else except the mountain areas and only a total of four original Kaiju appeared in an 11-episode series. This came from the fact that Tsuburaya Productions was still under a major financial crisis, having lost a legal battle with Chaiyo Productions back in early 2013. This was slowly averted starting in 2014, wherein Tsuburaya managed to repay ALL of their financial debts and Ginga S steadily showed an improvement in their show’s finances. With the next series Ultraman X and so on, the number of original-produced Ultra Kaiju suits increased by every year that even the Milestone Celebration show Ultraman Orb became a major attraction for the worldwide view.
- Off-the-Shelf FX: The Spark Dolls are simply the soft vinyl figures from the Ultra Hero 500 and the Ultra Monster 500 toylines, probably because the show has No Budget and Tsuburaya Productions needed good toy sales to resolve the financial crisis they were in when the series was produced.
- The Other Darrin: In a meta-sense in the Latin American Spanish dub: Unlike previous Ultraman series since Ultraman Tiga, which were dubbed in South American countries, mainly in Argentina, Colombia and Venezuela, this one was dubbed in Mexico for unexplained reasons.
- Promoted Fanboy: The actor of Hikaru Raido mentions that his favorite Ultraman is Ultraman Cosmos. The fact that he was able to act alongside Musashi's actor in the Ginga S movie was a huge excitement.
- Prop Recycling: The appearance of Thunder Darambia in the first episode was due to the fact that the staff had stumbled across the original Neo Darambia suit (specifically that of the second Neo Darambia) while rummaging the suit warehouse. The suit was in perfectly good condition despite not having been used for about fifteen years, so they decided to make good use of it.
- Refitted for Sequel: A booklet included with the series' Blu-ray boxset confirms that Dark Lugiel was partially inspired by Dark Lucifer, the scrapped final boss of Ultraman Nexus.
- Role Reprise: Two cases at that. Hiroya Ishimaru returns to voice Ultraman Taro since Ultraman Story in 1984 and suit actor Hideyoshi Iwata reprises his role as Dark Zagi.
- Screwed by the Lawyers: Later rereleases replace Legend of Galaxy with Ginga no Uta as the OP, due to rights issues with record company Johnny.
- What Could Have Been:
- The original concept of Ultraman Ginga was meant to be a continuation for Ultraman Gaia, taking place in the same universe as Gamu becomes a Badass Teacher and the protagonist is a university student. Additionally, they also tried Follow the Leader to Koichi Sakamoto's Kamen Rider Fourze.
- Because of the series's strong connection with Ultraman Taro, one of Ginga Strium’s early concept design’s sported Taro's horns, in addition to the armor. It was scrapped for clogging up Ginga Strium too much.
- In the middle of Ginga S, Taro was meant to be brainwashed by Exceller.
- The revived version of Dark Lugiel was originally considered as an Evil Knockoff of Ginga Strium.
- There were plans for a Latin American Dub of the series in 2014, which was actually finished and meant to debut on a streaming service, but the service's cancellation put an end to that and left the dub unreleased.
- You Look Familiar: Yuki Ono, the current voice actor of Ultraman Belial is none other than the Agent Peacock Berume.
