Spatial position nouns: 上, 下, 前, 後ろ, 中

Mental Model: The Preposition Flip

In English, prepositions come before the noun: “under the desk”, “on the chair”.

In Japanese, spatial indicators are nouns (position nouns). You must start with the solid anchor object first, connect it with the possession/linking particle の, and place the direction at the end:

• Pattern: [Anchor Object] + の + [Position Noun] + に
• 机の上(つくえのうえ) (tsukue no ue): “Top of the desk” -> 机の上に本があります (“There is a book on top of the desk”).
• 椅子の下(いすのした) (isu no shita): “Under the chair” -> 椅子の下に猫がいます (“There is a cat under the chair”).

Notice that the anchor is anchored first, then the spatial zone is pinpointed with に!

The 9 Essential Spatial Anchors

• Above / On top: 上(うえ) (ue) (テーブルの上 = on the table).
• Under / Below: 下(した) (shita) (ベッドの下 = under the bed).
• Front / In front: 前(まえ) (mae) (駅の前 = in front of the station).
• Behind / Back: 後ろ(うしろ) (ushiro) (ドアの後ろ = behind the door).
• Inside / Within: 中(なか) (naka) (かばんの中 = inside the bag).
• Outside: 外(そと) (soto) (家の外 = outside the house).
• Right next door / Adjacent: 隣(となり) (tonari) (銀行の隣 = right next to the bank).
• Near / Vicinity: 近く(ちかく) (chikaku) (学校の近く = near the school).
• Between: 間(あいだ) (aida) (AとBの間 = between A and B).

The Critical Distinction: 隣 vs 横 vs 近く

Foreigners frequently mix up these three words for “next to / nearby”:

• 隣(となり) (tonari) (Same Category Adjacent Neighbor):
• Used when two items of the same category sit directly side by side: building next to building (本屋の隣にカフェがある), person sitting next to person (田中さんの隣).
• 横(よこ) (yoko) (Horizontal Side / Across Categories):
• Neutral horizontal side. Can describe items of different categories: a trash can next to a vending machine (自販機の横にゴミ箱がある).
• 近く(ちかく) (chikaku) (General Radius / Vicinity):
• Indicates somewhere in the neighborhood or general area, without having to physically touch (駅の近く = near the station).
