Grandpa Higurashi

is the paternal grandfather of Kagome and Sōta Higurashi; as well as the father of the late Mr. Higurashi and father-in-law of Ms. Higurashi, and the great-grandfather of Mei Higurashi and Moroha. Grandpa often covered for Kagome's prolonged absences at school with interesting (and often absurd) excuses, which make Kagome's friends worry a lot about her.

History
At the Sōgō hospital, he praised that he had his first grandchild that is a baby girl.

In the manga, it is revealed that Kagome's mother is his daughter-in-law who moved to Higurashi Shrine after tragic death in a car accident that claimed the lives of his son and wife.

In the anime version, it is revealed that Kagome and her mother lived in the Higurashi Shrine since she was 4 years old after her father died in a car accident.

During the story
Grandpa continually tries to inject some education of the history of the family shrine into everyday life – even to the point of discussing the "history of pickles," much to Kagome's dismay.

Grandpa maintains the shrine grounds, buildings, the sacred tree, handles offerings, and the various Shintō religious ceremonies that are required. He tries to bring in some income to pay the bills by selling various religious paraphernalia, such as the Sacred Jewel key chains (日暮神社 四魂の玉 キ一ホルダ一).

He is skilled in handling objects brought to him that need to be blessed, cleansed, or sealed. His abilities save him from death. But Grandpa's powers are clearly overcome by Inuyasha as he breaks through Grandpa's Ofuda – or "written oracles." Although this could be because Inuyasha is only hanyō, it could also be because his charms don't work at all.

He revealed to Kagome how to destroy the Shikon no Tama, but she dismissesed him lightly.

Physical description
Grandpa is identified by his clothing as a traditional Japanese, apparently the current custodian/guardian/caretaker/owner of the Higurashi Shrine which has been in the family for generations.

 * Inuyasha

Grandpa doesn't like Inuyasha very much, thinking he is reckless and annoying. He once hired Inuyasha to worked part-time at the Higurashi shrine, then fired him when he knocked over some shelves. Though this was due to a "Sit" command from Kagome.

Trivia

 * He has a rather bad habit of giving so-called genuine demon artifacts to Kagome or Sōta as gifts, which annoys both of them; he also sometimes feeds them to Buyo. This apparently is something he never learns from, even after scolding from Kagome. Though he seems to not realize Kagome has dealt with genuine demons and knows they are fake.
 * However, Moroha seems to appreciate this far more than they do, seemingly being pleased with receiving the mummified Kappa foot for good luck, which Kagome rejected. It is possible that having been raised in the Sengoku jidai that she might believe in their supernatural properties, although this is unconfirmed.
 * , who voiced both Grandpa and Buyo, passed away due acute subarachnoid hemorrhage, leading to take over his voice acting roles.; who's also known for voicing as Diddy Kong.
 * Grandpa Higurashi's inability to use spiritual powers, along-side his deep-rooted belief that he possesses spiritual powers (and on an upper-level of spiritual powers, too), goes-hand-in-hand with Madame Exorcist; a professional exorcist, who steadfastly believes that she is a person of great spiritual prowess, despite of all of the evidence that she lacks any spiritual powers beyond what all normal humans have.
