10 No-Goes When You Intern at a Japanese Firm

Interning at a Japanese firm can feel like stepping into a world where every detail matters—punctuality, hierarchy, even how you hand over a business card. Having worked in Japan for a decade, I’ve had my share of “Oh no, did I just mess that up?” moments. If you’re headed for an internship in Japan, let me spare you a few of those by sharing the top 10 “no-goes” you should avoid at all costs.

1. Arriving Late—Even By a Minute

Let’s start with the obvious: punctuality. In Japan, being on time isn’t just polite—it’s a sign of respect. Show up late, and you risk tarnishing your reputation from day one. I once overheard a Japanese manager say, “If someone can’t manage their time, how can they manage anything else?” Harsh? Maybe. But fair in this culture. Pro tip: Aim to arrive 10–15 minutes early, just to account for unexpected train delays (yes, they happen, though not often!).

2. Ignoring the Hierarchy Game

Japanese workplaces are deeply hierarchical. Even in casual settings, seniority matters. Whether it’s addressing your manager with a respectful “-san” or letting the senior staff exit the elevator first, these little gestures go a long way. I’ll never forget my first office dinner when I accidentally poured my own beer before pouring my boss’s—cue awkward silence. Learn the unspoken rules early, and you’ll fit in smoothly.

3. Dressing Like It’s Casual Friday

Think business formal unless explicitly told otherwise. While some companies in Tokyo may embrace a more relaxed dress code, most prefer their interns to stick to conservative attire. Imagine a sea of black suits in a morning meeting—that’s the norm. Anything too bright, flashy, or casual will stand out—and not in a good way.

4. Half-Hearted Bowing

Bowing is both art and science. Too shallow? You seem insincere. Too deep? You’re overdoing it. For greetings, aim for about 15 degrees; for apologies, go deeper—around 30 degrees. A colleague once jokingly called my early attempts “the nodding pigeon.” Practice makes perfect, and it’s better to try than to skip bowing entirely.

5. Speaking Without Observing First

Japanese communication values harmony, and sometimes, silence speaks louder than words. In meetings, jumping in too quickly can come across as impulsive or disrespectful. I once presented an idea with what I thought was enthusiasm, only to realize I’d interrupted a manager mid-thought. Observe the room, wait for your cue, and contribute thoughtfully.

6. Being Glued to Your Phone

While the occasional glance at your screen might fly in other countries, in Japan, it’s considered unprofessional. Even during breaks, excessive phone use can make you seem disengaged. If you must check your messages, step away discreetly. Bonus: This habit will also help you soak in the cultural nuances around you.

7. Leaving a Mess Behind

Tidiness isn’t just a personal habit in Japan; it’s a societal value. Your workspace should be spotless. Forgetting to clean your coffee mug or leaving papers in disarray can earn you silent disapproval. I learned this the hard way after accidentally leaving a used tissue in a shared bin. The subtle looks of disappointment? I never repeated that mistake.

8. Refusing Small Tasks

As an intern, you might be asked to do seemingly mundane jobs—preparing meeting materials or taking notes. It’s not busywork; it’s a test of reliability. Saying “no” or acting like it’s beneath you? A surefire way to alienate your team. Remember: even Japan’s CEO culture is rooted in humility.

9. Eating at Your Desk

While eating at your desk is generally acceptable in many Japanese workplaces, it’s important to stay mindful of your surroundings. Avoid strong-smelling foods, and keep your area clean and organized. If your office has a designated break area, you might find it’s a better place to bond with colleagues. Remember, every workplace has its own unwritten rules—observe and adapt.

10. Forgetting Omotenashi

Omotenashi, the spirit of selfless hospitality, is woven into every aspect of Japanese culture. At work, this means being proactive and attentive. Offer to help with tasks, even if they’re not your responsibility. Say thank you often and mean it. These gestures may seem small, but they can leave a big impression.

Why These No-Goes Matter

You might wonder, “What’s the big deal about these little things?” The answer lies in how Japanese society values harmony (wa) and mutual respect. By avoiding these no-goes, you’re not just being polite; you’re showing your commitment to adapting and thriving in a new cultural environment.

A recent survey found that 89% of interns who made a conscious effort to embrace Japanese workplace etiquette felt their experience was significantly more rewarding. As someone who has been on both sides of the intern-manager dynamic, I can confidently say this: your effort won’t go unnoticed.

Final Thoughts

Interning in Japan is a once-in-a-lifetime opportunity to grow professionally and personally. While it’s easy to get overwhelmed by the cultural differences, remember that your colleagues want you to succeed. A little preparation, humility, and willingness to learn will take you far.

If you ever find yourself unsure about something, don’t hesitate to ask (politely, of course). Every mistake is a chance to learn, and trust me—10 years in, I’m still learning too. Good luck, and enjoy the journey!
