You’ve heard it in anime. You’ve heard it at the local sushi spot. Maybe you’ve even seen that viral clip of a bowing robot. But if you think you know what arigato in Japanese actually means, you’re probably only seeing about ten percent of the picture.
Language is messy.
Most textbooks give you the "thank you" translation and call it a day. That's a mistake. In reality, the word arigato carries a heavy historical weight and a social complexity that can make or break a conversation in Tokyo or Kyoto. If you use it with the wrong person, you don't just sound like a tourist—you might actually come across as rude. Seriously.
The Weird, Buddhist History of Arigato
Let's get nerdy for a second. The word didn't start as a greeting. It's a mashup.
The roots go back to the words ari (to exist) and gatou (difficult). Basically, the original vibe was "it is difficult for this to exist." It’s a Buddhist concept. Life is hard, miracles are rare, and if someone does something kind for you, it’s a statistical anomaly in a chaotic universe. You aren’t just saying "thanks for the coffee." You are literally acknowledging that the kindness you just received is a rare and precious event that shouldn't be taken for granted.
Over centuries, arigataku morphed into the arigato we know today. By the Edo period, it became the standard way to express gratitude, but it never lost that sense of "this is rare."
Why You Probably Shouldn't Just Say Arigato
Here is where it gets tricky for English speakers. In English, "thank you" is a Swiss Army knife. You say it to your boss, your dog, and the guy who held the elevator.
In Japan? Not so much.

If you just say "arigato" to a stranger or a superior, you’re being way too casual. It’s like walking up to a judge in court and saying "Sup, dude?" It’s jarring. To make it polite, you almost always need to add gozaimasu.
Arigato gozaimasu is the gold standard.
It adds a layer of formal "being" to the end of the phrase. It signals that you recognize the social hierarchy. If you’re at a store, use the full version. If you’re talking to a teacher, use the full version. If you’re talking to your best friend while eating ramen at 2 AM? Yeah, arigato is fine. But even then, there are nuances.
The Past Tense Trap
Have you ever finished a meal and felt the urge to say thanks? In English, we still say "thank you." In Japanese, the timing matters. If the action is finished, you often switch to arigato gozaimashita.
That shita at the end is the past tense. You’re thanking them for the specific thing that just happened, like a completed service or a gift you just opened. Using the present tense for something that happened yesterday feels slightly "off" to a native ear. It’s a tiny detail, but it’s the difference between sounding like a student and sounding like someone who actually lives there.
Is It Better to Say Sorry?
This is the part that blows most people's minds. Sometimes, the best way to say arigato in Japanese is to actually say "I'm sorry."
The word is sumimasen.

You probably know it as "excuse me," but it’s the most common way to say thank you in Japan. Why? Because Japanese culture is deeply rooted in the idea of "meiwaku" or causing trouble for others. When someone does something for you—like picking up a glove you dropped—they are spending their time and energy on you. You have inconvenienced them.
By saying sumimasen, you are acknowledging that inconvenience. You’re saying, "I’m sorry you had to go out of your way for me, and I appreciate it." It sounds heavy, but it's actually considered very polite and humble. In a crowded Tokyo station, you'll hear sumimasen ten times for every one arigato.
Regional Flavour: The Kansai Twist
If you head down to Osaka or Kyoto, things get fun. People there are famously more boisterous and have their own distinct dialect called Kansai-ben.
Instead of arigato, you might hear ookini.
It’s old-school. It’s charming. It basically means "greatly" or "extremely," shortened from a longer phrase that meant "thank you greatly." You won't see it much in business meetings in Shinjuku, but if you say it to a shopkeeper in an Osaka market, you’ll get a huge grin. It shows you’ve done your homework.
Formal vs. Informal: A Quick Breakdown
Let’s be real, you don't want to memorize a textbook. You just want to know what to say and when. Honestly, just follow these vibes:
- Doumo: This is the ultimate "lazy" thank you. It literally just means "very." You can use it when someone holds a door, but keep it brief.
- Arigato: Friends only. Siblings. People younger than you. Use it with your boss and you might get a very awkward look.
- Arigato gozaimasu: The safe bet. Use this 90% of the time. You can’t go wrong being too polite.
- Doumo arigato gozaimasu: The "I am incredibly grateful" version. Use this if someone literally saved your life or gave you a massive promotion.
- Azasu: This is slang. It's a crushed-down version of arigato gozaimasu used by young guys or athletes. It’s super casual and a bit "bro-y." Avoid it in formal settings.
The Body Language Factor
You can't talk about arigato in Japanese without talking about the bow. In the West, we make eye contact to show sincerity. In Japan, if you stare someone in the eye while saying thank you, it can feel aggressive.

A slight nod of the head (called eshaku) usually accompanies a casual arigato. For arigato gozaimasu, a deeper bend from the waist is more appropriate.
The deeper the bow, the more gratitude you’re showing. Just don't overdo it. You aren't auditioning for a period drama. A simple, crisp 15 to 30-degree tilt is perfect for everyday life. And whatever you do, don't do the "prayer hands" (palms together) when you bow. That’s a common mistake tourists make. It’s more of a Southeast Asian or religious gesture; in Japan, it’s mostly for praying at a shrine or apologizing profusely for a massive screw-up.
Does Anyone Still Say "Sankyuu"?
Yeah, actually. Katakana English is huge. Sankyuu (サンキュー) is used all the time in texting, among friends, or in casual signage. It’s lighthearted. It’s cute. But again, it’s not for your father-in-law. It has zero "weight." If you use it, you're signaling that the situation is totally chill and nobody needs to be formal.
Cultural Context: The Gift of Giving
Gratitude in Japan is often tied to giri, or social obligation. When you say arigato, you are sometimes acknowledging a debt. This is why gift-giving (omiyage) is so huge. If you go on a trip, you bring back snacks for the office to say "thanks for covering for me while I was gone."
The words are just the tip of the iceberg. The real "thank you" is the action that follows. Japanese culture values the "unspoken" (ishin-denshin). Sometimes, a silent, well-timed gift speaks much louder than shouting arigato across a room.
Practical Steps for Your Next Trip
If you’re planning to visit Japan soon, don't overthink the grammar. People are generally very forgiving of foreigners. However, if you want to show real respect, try these three things:
- Default to the long version. When in doubt, always use arigato gozaimasu. It shows you respect the culture.
- Watch the "shita". If you're leaving a restaurant or a hotel, use the past tense arigato gozaimashita. It sounds much more natural as you're walking out the door.
- Use your hands. Don't just say the word. If you’re receiving something, take it with both hands. It’s a silent way of saying "this matters to me."
Understanding arigato in Japanese isn't about memorizing a translation. It's about shifting your mindset. It’s moving from "I want this" to "I am grateful this exists." Once you get that, the language starts to make a lot more sense. You'll stop worrying about being "perfect" and start being present.
Next time you’re in Japan, try using sumimasen when someone does you a small favor. Watch their reaction. You’ll see a subtle shift in how they perceive you. You aren't just another tourist with a guidebook; you're someone who understands the quiet, rare beauty of a shared moment. That’s the real meaning of arigato.
Focus on learning the difference between arigato and arigato gozaimasu first. Practice saying them out loud to get the rhythm right—it's more of a "gato" than a "gay-to." Once you have the pronunciation down, start paying attention to how locals use sumimasen in shops. Observing these real-world interactions will teach you more than any app ever could. For your next step, try watching a Japanese vlog or a "slice of life" show and count how many different ways they express gratitude in just ten minutes.
