Hachiko

"I'll wait for you at Hachiko."

A purebred Akita dog from the early part of the 20th century who became a figure in Japanese folklore because of his Undying Loyalty to his dead master. At the end of every day, Hachiko would go to Shibuya Station in Tokyo and wait for his owner (Eisaburo Ueno, a professor at Tokyo University) to come home from work. Even after Ueno died in 1925 after a heart attack while at work, Hachiko continued this practice, and for the next 11 years (until his own death), he returned to the station at the end of the day to await his late owner's return.

After a 1932 newspaper article brought Hachiko to national attention, he became a permanent symbol of loyalty and faithfulness. A bronze statue of him now stands outside of Shibuya station in Tokyo. (Two more are found in Odate, one by its train station and one outside the Akita Dog Museum there.) The Shibuya statue is an extremely popular spot for people to meet, particularly lovers because of its symbolic representation of commitment and loyalty.

See also the Scottish version, Greyfriars Bobby, or the Australian version, the Dog on the Tuckerbox.

Anime and Manga

The main characters of Super GALS!! often congregate around the statue of Hachiko. (Or, in Ran's case, on the statue. Good boys and girls, don't do this.)
In Nana, one of the two main characters is nicknamed "Hachiko" because of her loyalty. The nickname is generally shortened to "Hachi," since "hachi" means "eight," and "nana" (the name of both main characters) means "seven."
Mirai briefly waits for a male friend (on whom she has a crush) by the statue of Hachiko in one episode of Moldiver.
- Furthermore, recovering the original Hachiko statue from thieves who had stolen it is one of the things that brings "Captain Tokyo" to the media's attention.
The statue can be seen in one episode's opening bumper in Risky☆Safety.
In the Love Hina Christmas movie, Hachiko's statue is one of the places where Naru and Keitaro fail to meet up on Christmas Eve.

In Digimon Adventure, Patamon gets lost and overhears a couple of teenage girls talking about how Hachiko is where to go if you want to meet up with someone. The dub just says "the park," though.
An appropriately squicky parody of Hachiko shows up in Franken Fran, who puts the loyal dog's brain in the body of a middle-aged man (she at least gives him underwear); the "dog" remains his usual affectionate self. Did I mention the dog's owner is a little girl? After defending his owner from rapists, the girl accepts and loves her dog, even if his form is a bit weird. Unfortunately she gets cancer and dies in a faraway hospital, leaving the poor dog-man to waste away while awaiting her return. Of course, a statue of the loyal man-dog is built in his memory.
- This is further parodied when a movie based on that case changes the middle-aged man to a handsome Bishounen. Veronica, who insisted on saving the dog in the first place, is horrified. Fran, on the other hand... Fran: "I thought they addressed the bestiality quite tastefully".
In Manga no Tsukurikata Morishita asks Takeda to meet her at Hachiko; she notes that country people seem to be fond of it.
In Tenchi in Tokyo, Nobuyuki (Tenchi's dad) blurted out "It's fashionable to meet at the Hachiko statue" in an attempt to be one of those "with it" dads. This was left in the dub, probably puzzling many.
The anime series Fortune Dogs includes in one episode an Expy of Hachiko which suffers the same fate as the real one.
An episode of Pokémon used the trope with a Ninetales guarding the shrine its trainer used to live in.

Film

In Gamera 3: Revenge of Iris, the statue is engulfed in flames during Gamera's mindless pursuit of the Gyaos as a big symbol that he is no longer "Loyal" to humanity.
Hachiko: A Dog's Story is a 2009 movie based on this. Instead of Japan, it takes place in the United States but the general idea is the same. The only reason the dog still has a Japanese name despite the setting is because he came from Japan and got separated in a train station from the cargo he was in. The main character finds him and the story begins.
- Technically, this is a remake of a 1987 film, Hachiko Monogatari, a Japanese film based on Hachiko's story.
In the 1945 film The Body Snatcher, a dog faithfully guards its late master's grave. Unfortunately, it's such a small dog that when a grave-robber comes, he easily kills it with one blow of a shovel.

Tabletop Games

The Yu-Gi-Oh! card game has a series of cards based on Hachiko. "Outstanding Dog Marron" is an adorable puppy with an effect that returns it to the Deck when it would be sent to the Graveyard. Three counterparts were released in later sets:
- "Mad Dog of Darkness" shows Marron corrupted by evil and mutated into a creepy and fearsome beast by dark powers - though the card itself doesn't call the dog Marron, it has the same dog tag as all the other cards in the series.
- "Mecha-Dog Marron" is a mechanized version with 1000 ATK and DEF that approaches the loyalty motif from a different angle - when destroyed and sent from the field to the Graveyard, it reliably inflicts 1000 damage to the opponent, though if it falls in battle the controller also takes 1000 damage.
- "Skull Dog Marron" is Marron's animated skeleton, which has been waiting for its master to come back even after 1,000 years. It's not nearly as creepy as "Mad Dog", though, and even ends up being quite cute when it appears in other cards' artworks.

Other

Neopets has Gelerts, which are based on an English version of the tale in which a family dog is found covered in blood with a child missing. The dog is killed immediately when the grief-stricken owner assumes that the dog had killed the child. The sound of the yelp the dying dog makes causes the hidden child to cry, where it is found next to the carcass of a wolf the loyal dog had killed while protecting the infant, and the source of the blood on the dog's muzzle.

Real Life

Greyfriars Bobby is a similar story that happened in Edinburgh, Scotland, in the 19th century. A terrier guarded his owner's grave until he dies himself.
Australia has a touching story about the Dog on the Tuckerbox - There was a drover, droving cattle. The mob of cattle gets bogged, and he set his dog to guard his tuckerbox (a box of food, for those who don't speak Aussie), and he left to go get help. He never returns, and the dog stays, faithfully sitting on the tuckerbox, "five miles from Gundagai". There's a small statue there to this day.
A rare comic example comes from the life of Carl Linnaeus, biologist and the Father of Taxonomy. Linnaeus attended church regularly, and in the company of his dog, named 'Pompe.' Linnaeus had a limit to his religion. He would stay at the service for an hour. If the service was not concluded at the end of an hour, Linnaeus (and dog) would leave. Linnaeus did, as all of us, occasionally catch ill, and he would not attend church. Nevertheless, his dog would attend church without him, and, true to his master's form, leave after an hour, sermon over or not.
In Spain in 1990, a dog named Canelo ("Canela" means "cinnamon" while "canelo" could mean "cinnamon-colored male") went to the hospital with his owner to receive a periodic dialysis treatment until one day that complications killed him.

To honor him, a street was named after the dog and a commemorative plate was installed in the street.
