Tokyo, a city where ancient traditions blend seamlessly with futuristic innovation, attracts millions of visitors each year. But beyond the tourist brochures and travel guides lies a wealth of local knowledge that can transform your experience from ordinary to extraordinary. Having spent considerable time navigating this magnificent metropolis, I've gathered insights from Tokyo residents about what they wish tourists understood before arriving.
Cash is Still King (Despite Appearances)
Despite Tokyo's high-tech image, many small restaurants, local shops, and even some tourist attractions operate on a cash-only basis. While major department stores and chain establishments accept credit cards, you'll find yourself stuck if you're counting solely on plastic.
"I always see tourists panicking when they realize they can't pay with their cards at my ramen shop," says Tanaka-san, a shop owner in Shinjuku. "They assume because we're 'high-tech Japan' that everywhere takes cards, but that's not true."
Make sure to carry yen with you, and know that 7-Eleven ATMs are reliable for international withdrawals when you need to restock.

The Silent Subway Code
Tokyo's subway system is remarkably efficient but governed by unwritten rules that locals wish tourists understood. Talking loudly, eating, or taking phone calls on trains are considered disruptive behaviors.
"The silence on trains isn't because we're unfriendly," explains Yuki, a Tokyo office worker. "It's about respecting everyone's space in a crowded city."
Priority seating is taken seriously here - those seats marked with different colors are genuinely reserved for elderly, pregnant women, or those with disabilities. Don't sit there unless you fall into those categories, especially during rush hours.
Food is Everywhere (But Reservations Matter)
One delightful surprise for visitors is that quality food exists literally everywhere in Tokyo. From train stations to department store basements (depachika), you're never far from an excellent meal.
However, for popular restaurants—especially those featured in guidebooks or with recent media attention—reservations are often essential. Many top-rated places book out weeks or even months in advance.
"It breaks my heart when I see tourists standing disappointed outside famous sushi restaurants," shares Keiko, who works near Tsukiji. "With a bit of planning, they could have secured a spot instead of missing out."
What's With the No Trash Cans?
Perhaps the most baffling aspect of Tokyo for visitors is the scarcity of public trash cans, despite the city's immaculate streets.
"We carry our trash home with us," explains Hiroshi, a university student. "It's just part of our responsibility to the community."
This practice dates back to the 1995 sarin gas attacks, when many public trash receptacles were removed as a security measure. Today, you'll find some bins near convenience stores and vending machines, but plan to keep a small bag for your trash until you find a proper place to dispose of it.
Is It Rude to Tip?
"Please stop trying to tip us!" laughs Mari, a bartender in Roppongi. "We actually find it uncomfortable and sometimes even offensive."
Unlike in America, tipping is not customary in Japan and can create awkward situations. The price you're quoted includes service, and excellent service is simply the standard expectation. Your sincere "arigatou gozaimasu" (thank you very much) is more appreciated than extra yen.
Beyond the Tourist Traps
Tokyo locals wish tourists would venture beyond the Instagram-famous spots like Shibuya Crossing and explore neighborhoods like Shimokitazawa, Koenji, or Yanaka for a more authentic experience.
"The real Tokyo exists in these smaller neighborhoods," insists Daisuke, a lifelong resident. "That's where you'll find the soul of our city."
Remember that Tokyo isn't just a destination—it's home to millions of people navigating daily life. Approaching the city with respect and curiosity will open doors to experiences that no guidebook can provide.
