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.
この車の緩衝器はとても丈夫だ。
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.
鉄道のバッファが衝撃を吸収する。
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.
ショックアブソーバーを交換する必要がある。
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.
貯金は不況に対する緩衝材になる。
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.
彼の存在がチームのクッションの役割を果たしている。
His presence serves as a buffer for the team.
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.
Standard term in computing. Used in phrases like バッファメモリ (buffer memory) or バッファリング (buffering).
動画がバッファリング中です。
The video is buffering.
Variant spelling, equally common. Often used in technical documentation.
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.
その国は二大国の間の緩衝地帯となっている。
That country serves as a buffer zone between the two superpowers.
Loanword used in similar contexts, especially in environmental or urban planning.
川沿いにバッファゾーンを設ける。
Establish a buffer zone along the river.
A solution that resists changes in pH when acids or bases are added.
Standard term in chemistry for a buffer solution.
実験では緩衝液を使ってpHを一定に保つ。
In the experiment, we use a buffer solution to keep the pH constant.
Also used in chemistry, often in compound terms like バッファー溶液 (buffer solution).
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.
ポリッシャーで床を磨く。
Polish the floor with a buffer.
Loanword from 'buff', used for a cloth or tool for polishing, especially in car detailing or crafts.
車のワックスをバフで仕上げる。

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.
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。
