Is the TV show My Grandfather, the Master Detective available on Netflix, Disney+, Prime or Apple TV+?

At Stream Tracker, we look at where to watch the new drama My Grandfather, the Master Detective (2026) — a quiet, heartfelt series that trades classical sleuthing for a different kind of case. When elementary school teacher Kaede reunites with the grandfather who raised her, she’s suddenly facing the unraveling clues of Lewy body dementia: fading memories, shifting truths, and the fragile traces of a shared past. The show uses detective imagery — clues, red herrings, long-buried evidence — to explore memory, family duty, and the small investigations of everyday life. This article will tell you whether the series is available on Netflix, Disney+, Prime Video, or AppleTV+, and how to stream it where you are. If the series has received awards or festival recognition, those accolades will be noted as well.

Synopsis

Elementary school teacher Kaede returns to reunite with the grandfather who raised her just as he begins to live with Lewy body dementia; together they must adapt to shifting routines, memory lapses and emotional strain, confronting the practical and personal challenges that test and ultimately reshape their relationship.
