Onsen Tamago, the turtle, is named after a type of Japanese snack. It consists of eggs that were soft-boiled in a hot spring. The name literally translates to "hot springs eggs".
In Episode 8, "The Legend of the Hot Springs Turtle", the twin Mutsumi fairies sing to summon a giant Tama-chan. This is a parody of a scene in Mothra, in which a pair of twin fairies sing a song to summon Mothra.

The character "Akamatsu" who appears in both the "Love Hina Christmas Movie" and the "Love Hina Spring Movie" is in fact Ken Akamatsu, author of the original manga, a fact that both he and some of the Hinata girls make reference to in the latter film.
According to author Ken Akamatsu, the four beast-gods of ancient Japanese myth appear in Love Hina in the form of the various pets: Genbu is Onsen Tamago, the hot springs turtle; Byakko is Kuro, Kanako's cat; Suzaku is Shippu, the mysterious bird owned by Tsuroko (Motoko's elder sister); and Seiryuu is the iguana owned by Ema Maeda (a manga-only character).
There is a 25th episode to the series - the first episode made for a cancelled second season - which can be found on the North American release DVD of the "Love Hina Christmas Move".

Motoko is based on elements from Rumiko Takahashi's series, "Inuyasha" (2000). Her sword attacks are inspired directly by those Inuyasha himself used, while her appearance was taken from Kikyo of that series.
In the early sketches for what would become the Love Hina manga/anime series, Naru was known as Midori, and lacked the "hair antenna" she would become well-known for.
