GAPPU-RI がっぷり
Meanings
Describes two large or heavy things engaging firmly so that they do not separate; especially familiar from the sumo expression GAPPU-RI YOTSU, in which two wrestlers take each other’s belts and meet chest to chest.
Examples
・Take that job seriously and tackle it head-on.
その仕事、真剣にがっぷり（四つで）取り組んで。
The two wrestlers locked up chest to chest in a full belt grip.
↓Gappuri Yotsu
Dogmatic Opinion
The representative expression is GAPPU-RI YOTSU, a sumo position in which both wrestlers have grips on each other’s mawashi and are locked together chest to chest.
From that physical image comes the figurative use: two sides confronting a task, problem, or opponent squarely and seriously rather than avoiding it.
GAPPU-RI can also describe biting into something and not letting go.
The shared image is a strong, direct engagement between two sides.

For Japanese Learners
English depends on context: locked firmly together for the physical image; squarely, head-on, or fully engaged for figurative use. Because GAPPU-RI YOTSU is culturally tied to sumo, a brief explanation is often more useful than forcing a one-word translation.
