The Difference Between 「すぐ」と「ただいま」の会社での使い分けの違い｜Japanese Grammar (N5–N3)

(Joy jogging energetically saying Sugu [Casual] vs. Ken walking elegantly saying Tadaima [Professional])

“I’ll go right away!” (To a coworker) -> すぐ行きます！ (Standard Polite) “I will be right there.” (To a boss/client) -> ただいま参ります。 (Professional / Elegant) When someone calls your name, you want to show that you will respond quickly. In daily life, すぐ (Sugu) is the perfect word. But in a Japanese business setting, “Sugu” can sound a little bit raw or childish. To show true professional polish, you need to use ただいま (Tadaima). Let’s see what happens when Joy is called by her manager.

🗣 Conversation Scene

Director Tanaka needs Joy’s help with a document and calls her from across the room.

Tanaka

Joyさん、ちょっとここに来てくれますか？ (Joy, could you come here for a second?)

Joy

はい、すぐ行きます！ (Yes, I’ll go “sugu” [right away]!)

[ Ken whispers to Joy to help her sound more professional. ]

Ken

Joyさん、上司には「すぐ行きます」よりも、「ただいま参ります」の方が、大人っぽくてプロフェッショナルに聞こえますよ！ (Joy, to a boss, saying “Tadaima mairimasu” sounds much more mature and professional than “Sugu ikimasu”!)

💡 Explanation

Everyday Urgency vs. Business Elegance

⚠️ The Golden Rule of Immediacy: すぐ (Sugu) focuses on the speed of the action (casual/standard). ただいま (Tadaima) focuses on the present moment and adds an elegant, professional wall of respect.

1. すぐ (Sugu) = Right away / Soon 👟

Target: Coworkers, daily life, friends. “Sugu” is perfectly fine for everyday situations and working with people of the same rank. However, because it is an everyday word, using it with a high-level boss or an important client makes you sound a bit like a student responding to a teacher. It lacks corporate polish.

[To a coworker] すぐやります！ (I’ll do it right away! *Energetic but standard*)
[On a casual team chat] すぐ送ります。 (I’ll send it soon. *Standard office use*)

2. ただいま (Tadaima) = Immediately / Currently 🏢

Target: Bosses, clients, customers, VIPs. Written with the kanji 只今, it literally means “right now.” When used for future actions (“I will go right now”), it sounds incredibly elegant and respectful. It is almost always paired with Humble Language (Kenjougo). It is also heavily used in customer service (e.g., “Tadaima kakunin itashimasu” – I am checking right now).

[When called by a boss] ただいま参ります。 (I will be right there. *Highest respect*)
[To a client waiting] ただいまお持ちいたします。 (I will bring it immediately. *Professional service*)

📊 Comparison Table

Word	Nuance	Who to use it with
すぐ (Sugu)	Standard Urgency. Focuses on speed and action.	Coworkers, friends, everyday situations.
ただいま (Tadaima)	Professional Urgency. Elegant and respectful.	Bosses, clients, customers (often with Kenjougo).

🚧 The “I’m Home” Trap

You probably learned that ただいま (Tadaima) is what you say when you arrive home (“I’m home!”). Because of this, beginners sometimes walk back into their office after a meeting and happily shout, “Tadaima!” Do not do this! Your office is not your house. When returning to the office, you should say 戻りました (Modorimashita – I have returned).

Q1. A very important client calls you. They want you to check a file, but you need 30 seconds to open it. What do you say? A. Sugu kakunin shimasu. B. Tadaima kakunin itashimasu.

Answer: B (Tadaima kakunin itashimasu) When speaking with a client, you must use the highly professional “Tadaima” combined with humble verbs.

Q2. A coworker from your team asks if you can send them a link on Slack. A. Hai, sugu okurimasu! B. Hai, tadaima o-okuri itashimasu.

Answer: A (Sugu okurimasu!) With a close team member on chat, “Tadaima” is too stiff and overly formal. “Sugu” is perfect here.
