というもの means during; for; since; over a period of time. It is a JLPT N1 Japanese grammar pattern used to emphasize that a state or action continues across an entire span of time, often with a sense of “all this time” or “ever since.”
This grammar point often appears in essays, narratives, and JLPT N1 reading passages. If you want to stress that something has been going on for what feels like a long time, or that a change began at a specific moment and has persisted ever since, というもの is a useful pattern to learn because it adds emotional weight and precision to your Japanese.
What does というもの mean?
Use というもの when you want to mark a time period as an unbroken whole—what happens inside that period is continuous or unchanging. It often carries a sense that the duration is notable, burdensome, or surprising.
Natural translations include:
- during; for; since; over a period of time
The best translation depends on the sentence. Notice first whether the time expression is a length (e.g., 一週間) or a starting point (e.g., それから). Then pick the English that matches the sense of “throughout that whole stretch.”
How to form というもの
Concrete patterns often seen:
The time word before the grammar point can be a duration (三日間、一年) or a point in time (先週から、あの日から). The から version is extremely common and functions as “ever since …”.
When is というもの used?
Use というもの in situations like:
- describing a continuous state that fills an entire period
- reacting to a change that started at a turning point and has not stopped
- adding emotional color—frustration, loneliness, surprise—about how long something has lasted
Tone and register:
- Slightly formal; natural in writing and careful speech
- Common in test questions, personal narratives, news reports, and JLPT N1 reading
When you see it in a passage, the writer is usually inviting you to feel the weight of time.
というもの example sentences

彼が引っ越してからというもの、毎日が寂しい。
Ever since he moved away, every day has felt lonely.
この一か月というもの、毎晩残業している。
I've been working overtime every single night for this entire month.
入院中というもの、本ばかり読んでいた。
Throughout my hospital stay, I did nothing but read books.
卒業してからというもの、一度も母校を訪れていない。
I haven't visited my old school even once since graduation.
妻が病気になってからというもの、彼はまったく笑わなくなった。
Ever since his wife fell ill, he hasn't smiled at all.
After reading each sentence, ask what job というもの is doing: it frames the whole time period as one unbroken block where the situation stayed the same. That makes the nuance easier to remember than a one-word translation.
Nuance of というもの
The key nuance is a state or action fills the entire span, often with a feeling of heaviness or significance.
A plain time marker like ～間 simply says “during.” というもの adds the idea that the duration is long enough to matter—it might be burdensome (“a whole week of rain”), lonely (“ever since you left”), or remarkable (“all month, every night”). This emotional weight is why the pattern appears so often in personal stories and JLPT reading comprehension.
というもの vs ～以来
Both ～からというもの and ～以来 can express “ever since,” but they are different.
～からというもの
emphasis on unbroken continuity; emotional
Often used when the result is a continuous state or feeling that fills the entire time up to now.
彼が去ってからというもの、部屋が静かだ。
Ever since he left, the room has been quiet (and that quietness fills the whole stretch).
～以来
neutral statement of "since"; factual
Frequently used in formal writing to state that something has not happened or has continued since a definite point.
彼が去って以来、連絡がない。
Since he left, there has been no contact (statement of fact).
If both translations seem possible, check the tone: からというもの is more personal and vivid; 以来 is drier, often found in news or academic prose.
Common mistakes with というもの
A helpful practice method is to write one sentence with ～からというもの, then rewrite it with ～以来. If the meaning or tone changes, explain that difference in your own words.
Is というもの on the JLPT?
Yes. というもの is commonly taught as JLPT N1 grammar.
That means learners should be able to:
For test preparation, study the grammar point in full sentences. JLPT questions often test whether you can feel the weight of the time expression, not just its dictionary meaning. Look for the combination of a time marker with a continuous state (ている、ていた) or a negative statement that has persisted since a turning point.
Practice questions for というもの
Keep your first sentences simple. Once the structure feels natural, add more context so the emotional weight becomes clear.
Learning path for というもの
To learn というもの efficiently, start with its formation, then compare it with similar patterns, and finally practice in context.
Related grammar to review next
- とあいまって — because it also describes how two factors combine over time, adding a formal frame to a situation
- とあれば — because it uses a similar と-phrasing to set up an emphatic condition
- とあって — because it shares the と- construction and marks a situation as salient or recognizable
- とばかりに — because it, too, uses と to dramatize a state or manner, showing how N1 patterns often pack strong imagery into a compact form
Each of these patterns deepens your feel for the emphatic, often written tone that characterizes N1 grammar. Tackling them as a set makes the stylistic register more intuitive.
