(Joy skipping a year on a timeline [~Oki] vs. Ken checking off every consecutive year [~Goto])
“We hold this event every year.” -> 1-nen goto
“We hold this event every other year.” -> 1-nen oki
If you’ve ever felt confused by these two words, don’t worry—you are not alone! Even advanced learners sometimes mix them up because they look so similar. But once you understand the simple logic behind them, you will never make a scheduling mistake again. Let’s clear it up directly and easily with Joy and Ken!
🗣 Conversation Scene
Joy and Ken are enthusiastically planning the events for the JPLT 2026 project.
(Ken, I want the massive JPLT 2026 offline event to be a huge success! From now on, let’s hold it “1-nen oki”! If we do it every year, the students will be happy!)
「１年おき」は「１年スキップする（2026, 2028…）」という意味になっちゃいますよ。毎年の場合は「１年ごと」です！
(Joy, that’s a wonderful idea, but watch out for the word trap! “1-nen oki” ends up meaning “skip a year (2026, 2028…)”. If it’s every year, it’s “1-nen goto”!)
💡 Explanation
Consecutive vs. Skipping
1. 〜ごと (~Goto) = Every / Consecutively 📅
Logic: No gaps. It happens at every point on the timeline.
When you say 1年ごと (1-nen goto), it means it happens at Year 1, Year 2, Year 3… It is exactly the same as saying 毎年 (Maitoshi – every year).
- オリンピックは 4年ごと に開催（かいさい）されます。
(The Olympics are held every 4 years. *No skipping the 4-year mark*) - 1日ごと に 薬を飲む。
(Take medicine every single day.)
2. 〜おき (~Oki) = Leave an interval / Skip 🦘
Logic: Leave a gap.
The verb 置く (oku) means “to place/leave”. So, 1年おき (1-nen oki) means “leave 1 year as an empty gap.”
If you do it in 2026, you *leave* 2027 empty, and do it again in 2028. In English, this is “Every other year.”
- 1日おき に ジョギングをする。
(I jog every other day. *Mon: Jog, Tue: Rest, Wed: Jog*) - この電車は 1駅おき に止まります。
(This train stops at every other station. *Skips one station*)
📊 Visualizing the Timeline
🚧 The Time & Distance Exception!
There is ONE major exception to this rule. For continuous measurements like Minutes (分), Seconds (秒), and Meters (メートル), leaving an interval of 5 minutes is the exact same thing as taking an action every 5 minutes. Therefore:
5分ごと (5-fun goto) = 5分おき (5-fun oki)
They both mean “Every 5 minutes”! Don’t overthink this one—for time on a clock, they are interchangeable!
