Bows, kotatsu, omiyage, the silent grammar of a polite room — the parts of Japan a guidebook can't quite explain in a list.
In a Japanese room the seats are not interchangeable. Kamiza and shimoza quietly decide who is honoured and who ends up handling the bill. JP: 上座と下座——座る場所が語ること
In Kinosaki, the yukata is not a costume but the town's evening uniform — worn to dinner, to seven public baths, and clacking down a willow-lined street on wooden geta. JP: 浴衣は左が上——城崎温泉の作法
Before the menu is settled, a warm towel arrives on a small tray. What the oshibori is for, what it isn't, and why it comes hot in winter and cold in summer. JP: おしぼりは、注文の前に来る
The sleeve machine at the door, the locker with a key, the identical clear umbrella in the honour stand — what Japan does with rain, and the grammar no guidebook lists. JP: 濡れた傘の、静かな作法
In an izakaya, the beer arrives in one large bottle for the table — and the rule underneath the noise is that you fill everyone's glass but your own. JP: 手酌をしない席、注ぎ注がれる作法
Your note is out, and nobody is reaching for it. The shallow tray between you and the cashier is doing quiet work worth understanding before you land. JP: レジの小さなトレー、お金の受け渡し
Before anyone speaks, a taxi, a meeting table or a tatami room has already assigned everybody a place. The rule is simpler than it looks. JP: 上座と下座――入口から遠い席の話
In a Japanese room the seats are not equal. The recessed alcove ranks them before you arrive — here is how to read it, and where you will actually meet the rule. JP: 床の間が決める、和室の座る場所
In most Japanese shops the cashier will not take coins from your hand. Meet the karuton — the small ribbed tray that quietly reorganises every transaction. JP: レジ横の小さなトレー、その意味
Take your shoes off, turn them to face the door, stop the slippers at the tatami — and never let the toilet pair wander. A field guide to reading a Japanese entryway. JP: 玄関で靴を脱ぐということ
The genkan looks like a place to leave your shoes. It is really a place where the terms of a visit are set — read it correctly and the rest of the house makes sense. JP: 敷居を越える前に：靴を脱ぐ理由
