Say how often you do things: Frequency Adverbs

Mental Model: The 6-Point Habit Thermometer

Frequency adverbs describe how habitually an action occurs. In Japanese, they require no particles of their own and sit comfortably right after the topic or right before the verb phrase.

Mastering frequency adverbs comes down to placing them along a clear percentage scale:

• 100% · Always: いつも
• Habitual default, routine without fail.
• 朝はいつもコーヒーを飲みます(あさはいつもこーひーをのみます): “I always drink coffee in the morning.”
• 80% · Often / Frequently: よく
• High frequency, a regular leisure habit.
• 休みの日はよく図書館へ行きます(やすみのひはよくとしょかんへいきます): “On days off, I often go to the library.”
• *Note: よく also means “well” or “skillfully” (よくできました).
• 50% · Sometimes: 時々(ときどき) (tokidoki)
• Roughly half the time; intermittent occurrences.
• 夜は時々自炊をします(よるはときどきじすいをおこないます): “At night, I sometimes cook for myself.”
• 20% · Occasionally / Once in a while: たまに
• Less frequent than ときどき; occasional treats or exceptions.
• たまに映画館に行きます(たまにえいがかんに行きます): “I occasionally go to movie theaters.”
• 10% · Rarely / Not often: あまり + Negative Verb
• Requires a negative verb ending. Means “not very much / rarely”.
• 朝ご飯はあまり食べません(あさごはんはおあまりたべません): “I rarely eat breakfast.”
• 0% · Never / Not at all: 全然(ぜんぜん) (zenzen) + Negative Verb
• Complete zero occurrence. Requires a negative verb ending.
• お酒は全然飲みません(おさけはぜんぜんのみません): “I don't drink alcohol at all.”

The Mandatory Negative Polarity Lock

Foreign learners often trip over あまり and 全然. In standard Japanese and JLPT N5 tests, these two adverbs are strictly negative polarity items:

• あまり MUST pair with a negative verb:
• Correct: あまり見ません(あまりみません) (“I don't watch it often”).
• Incorrect: *あまり見ます (Unnatural!).
• 全然 MUST pair with a negative verb:
• Correct: 全然わかりません(ぜんぜんわかりません) (“I don't understand at all”).
• Incorrect: *全然わかります (Ungrammatical in standard Japanese).

*(Note: In modern casual youth slang, you will hear native speakers use 全然大丈夫 or 全然いいよ meaning “totally fine”, but in formal grammar and proficiency exams, 全然 strictly pairs with negative predicates).*

Natural Sentence Placement

Because frequency adverbs modify the predicate directly, they never take particles like に or で. You can place them in two equally natural spots:

1. Directly after the topic: - 田中さんはいつも7時に起きます(たなかさんはいつもななじにおきます) 2. Directly before the verb phrase: - 田中さんは7時にいつも起きます(たなかさんはななじにいつもおきます)
