完成 em 30 segundos
- Kansei means 'completion' specifically for things being created or built.
- It is used for buildings, art, systems, and physical products.
- It differs from 'owaru' (general finish) and 'kanryou' (process finish).
- Grammatically, it functions as a noun or a 'suru' verb (完成する).
The word 完成 (kansei) is a cornerstone of the Japanese language when discussing the culmination of effort. At its core, it signifies the moment a project, object, or creative endeavor reaches its intended final state. Unlike simple completion of a task, 完成 implies that something tangible or conceptual has been 'built' or 'perfected'.
- Core Concept
- The achievement of a final form after a process of creation or construction.
- Physical Context
- Used for buildings, puzzles, models, and infrastructure.
- Abstract Context
- Used for systems, plans, works of art, or musical compositions.
「ついに、新しい家が完成しました！」 (Finally, the new house is complete!)
「このパズルは、あと一つのピースで完成だ。」 (This puzzle will be complete with just one more piece.)
- Etymology: 完 (Kan)
- Means 'perfect' or 'end'. It visualizes a roof over a person, suggesting a finished shelter.
- Etymology: 成 (Sei)
- Means 'to become' or 'to achieve'. It represents a weapon and a nail, symbolizing the successful forging of a tool.
「ダムの建設が完成に近づいている。」 (The construction of the dam is approaching completion.)
Using 完成 (kansei) correctly requires understanding its grammatical versatility as both a noun and a Suru-verb. It is a formal yet common word that appears in news reports, business meetings, and daily conversations about hobbies.
1. As a Noun (完成)
When used as a noun, it often follows a possessive or describes the state of an object.
- 完成予定 (Kansei yotei): Scheduled completion date.
- 完成品 (Kanseihin): Finished product.
- 完成度 (Kanseido): Degree of perfection/completion.
「この映画は完成度が高い。」 (This movie has a high level of completion/perfection.)
2. As a Suru-Verb (完成する)
This is the most common verbal form. It can be used intransitively (something finishes) or transitively (someone finishes something).
- Intransitive Use
- ビルが完成した (The building was completed).
- Transitive Use
- 論文を完成させた (I completed the thesis).
「3年かけて、ようやくシステムが完成した。」 (After taking three years, the system is finally complete.)
You will encounter 完成 in various specific environments. It is not just a word for 'done'; it is a word for 'arrival'.
In the News
Reporters use it for infrastructure, space missions, or new technology. 'The new stadium is complete' or 'The vaccine development is complete'.
「リニア中央新幹線の完成が待たれる。」 (The completion of the Linear Chuo Shinkansen is eagerly awaited.)
In Hobbies and Crafts
If you follow Japanese YouTubers who do DIY, plastic models (Gunpla), or cooking, you will hear this word at the climax of the video.
- Cooking Shows
- 「これで、特製カレーの完成です！」 (And with that, the special curry is complete!)
- DIY/Crafting
- 「ついにプラモデルが完成しました。」 (Finally, the plastic model is finished.)
Learners often confuse 完成 (kansei) with other 'finish' words. Understanding the boundaries is key to natural Japanese.
1. Kansei vs. Owaru (終わる)
'Owaru' is general. 'Kansei' is for creating. You don't 'kansei' a meeting; you 'owaru' a meeting.
❌ 宿題が完成した。 (My homework is 'completed' as a masterpiece? Unlikely.)
✅ 宿題が終わった。 (I finished my homework.)
2. Kansei vs. Kanryou (完了)
'Kanryou' is administrative or technical. It means a process is over. 'Kansei' means the object exists in its final form.
- Software Update
- Update 'Kanryou' (The process finished). You wouldn't say the update 'Kansei' unless you built the update itself.
- Registration
- Registration 'Kanryou' (Process done). Not 'Kansei'.
To enrich your vocabulary, compare 完成 with these related terms:
- 完了 (Kanryou)
- Completion of a procedure or task. Focuses on the 'end of the action'.
- 終了 (Shuuryou)
- The end of a period or event (e.g., a movie ending, a sale ending).
- 達成 (Tassei)
- Achievement of a goal or target (e.g., reaching a sales target).
- 完結 (Kanketsu)
- Conclusion of a story or series (e.g., a manga series ending).
「プロジェクトが完了し、成果物が完成した。」 (The project was concluded, and the deliverables were completed.)
