Translation guide
The English word "buffer" has several distinct meanings, from a physical shock absorber to a computer memory area to a figurative cushion. This guide covers the most common ways to express these ideas in Japanese, focusing on natural, everyday usage.
A device or material that reduces impact or vibration, such as on a vehicle or machine.
General term for a shock absorber or buffer device. Used in mechanical and engineering contexts.
This car's shock absorbers are very sturdy.
Loanword from English, used in technical contexts like railways (buffer stops) or computing. Less common for vehicle shock absorbers.
The railway buffer absorbs the impact.
Specifically refers to shock absorbers in vehicles. More precise than 緩衝器 but less common in general use.
I need to replace the shock absorbers.
Something that provides protection or reduces the impact of a difficult situation, such as financial reserves or emotional distance.
Literally 'cushioning material', used both physically (packaging) and figuratively for something that softens a blow.
Savings act as a buffer against a recession.
Means 'to serve as a cushion'. A natural way to describe something that softens an impact or provides a buffer.
Loanword used in business or IT contexts for a figurative buffer, like a buffer zone or time buffer. Less natural in everyday speech.
A temporary storage area in computing for data being transferred between devices or programs.
A neutral area separating opposing forces or groups, often in geopolitical or ecological contexts.
Standard term for a buffer zone, used in politics, military, and environmental contexts.
That country serves as a buffer zone between the two superpowers.
Loanword used in similar contexts, especially in environmental or urban planning.
Establish a buffer zone along the river.
A solution that resists changes in pH when acids or bases are added.
A tool or person that polishes or shines a surface, such as a floor buffer.
Common term for an electric floor polisher/buffer. Also used for nail buffers.
Polish the floor with a buffer.
Loanword from 'buff', used for a cloth or tool for polishing, especially in car detailing or crafts.
Finish the car wax with a buffer.
When using 'buffer' figuratively, avoid directly translating with バッファ unless in a technical context. Instead, use 緩衝材 or クッションの役割 for a more natural expression.
緩衝 (かんしょう) is the native Japanese term for buffering/cushioning and is used in physical, chemical, and geopolitical contexts. バッファ is a loanword primarily used in computing and some technical fields. For general shock absorption, 緩衝器 is preferred; for computer memory, バッファ is standard.
His presence serves as a buffer for the team.
スケジュールにバッファーを設ける。
Build a buffer into the schedule.
バッファーサイズを変更する。
Change the buffer size.
このバッファーは酸性条件下で効果的だ。
