[TravelNotes]Five Things to Watch Out For When Traveling in Japan

You've practiced "arigatou" and "sumimasen" and arrived in Japan full of confidence — only to be met with a series of unexpected baptisms by fire. Spotless streets with no trash cans in sight, high-tech toilets bristling with buttons, a payment culture where cash still reigns supreme, labyrinthine urban rail networks, and the mysterious ticket vending machine blocking the entrance to your ramen shop — Japan welcomes travelers warmly while quietly putting them to the test. Know these five things in advance, and your trip will be dramatically smoother.

1. Trash Cans Are Nowhere to Be Found

Japan's streets are immaculate, yet public trash cans are strikingly scarce — something that catches most visitors off guard.

• The confusion: You'll find yourself carrying an empty plastic bottle or takeout wrapper around for hours. The biggest historical reason for this dates back to the 1995 Tokyo subway sarin attack. Police and railway operators concluded that trash cans could serve as hiding spots for explosives and dangerous materials, and as part of counterterrorism measures, bins were removed en masse from stations and public spaces. Even decades later, they never fully came back — safety concerns and maintenance costs kept the status quo in place. Japan's cultural norm of "take your own trash home" is also a contributing factor.
• The fix: Hunting for bins next to vending machines, inside convenience stores, or on station platforms becomes a rite of passage for visitors. But the real stress-free solution is slipping a small plastic bag into your bag before you head out.
  

2. High-Tech Toilets with Too Many Functions

Japan's bidet-equipped washlets inspire awe — but on first encounter, they can be downright intimidating.

• The confusion: "Which button flushes?" "What happens if I press the one that says oshiri?" The sheer number of buttons on the control panel is enough to make anyone freeze.
• The fix: Just point Google Lens at the control panel and it will instantly translate kanji like oshiri (bottom wash), bidet, and flush into your language. Pictograms are becoming more universal, but the Otohime (sound princess — a device that plays flushing sounds for privacy) still catches many visitors completely off guard.

3. Cashless Payments Are Less Advanced Than You'd Expect

Come in expecting a high-tech nation and the analog reality can throw you off. "Cash only" signs are still surprisingly common, even at tourist destinations.

• The confusion: Famous shrines, temples, and beloved old-school local restaurants frequently accept cash only. Smartphone payments have grown in cities, but you'll still see people fumbling with coins when buying good-luck charms or train tickets. Part of the reason lies in how hatsuhoryo (offerings) and ofuse (donations) are classified — as religious acts rather than commercial transactions. Shrines and temples also worry that accepting digital payments could invite tax authorities to reclassify the sale of omamori (amulets) and ofuda (talismans) as taxable retail activity rather than a religious practice, exposing them to potential liability.
• The fix: ATMs at convenience stores (particularly 7-Eleven) accept foreign-issued cards 24 hours a day and offer multilingual interfaces. Worth noting: as of March 2026, contactless credit card payment has become available on nearly all private railways in Tokyo.

4. Urban Rail Networks That Are Genuinely Labyrinthine

The rail maps of Tokyo and Osaka in particular are full-on dungeons.

• The confusion: The same station can have separate ticket gates for JR, subway, and private rail lines. Trains on the same line stop at different stations depending on whether they're tokkyu (limited express), kyuko (express), kaisoku (rapid), or futsu (local).
• The fix: Google Maps is solid, but for navigating Japan's more complex private lines and figuring out which exit to use, these are the gold standards:
  • Japan Transit Planner (Jorudan): Available in multiple languages, it even tells you which train car to board to be closest to your exit or transfer staircase.
  • Pro tip: The yellow tactile paving strips on station platforms are designed for visually impaired passengers, but they also tend to lead toward the main exits. When lost, follow the yellow line to the widest ticket gate area.

5. The Ticket Vending Machine: A Formidable Wall

The food ticket machines (shokken-ki) common at ramen shops are the pinnacle of efficiency — but a genuine obstacle for the uninitiated.

• The confusion: It's a double whammy: the pressure of a line forming behind you, combined with a machine covered in buttons and zero photos. You can't tell which is the main dish and which are toppings (seasoned egg, extra chashu), and more than a few travelers have accidentally ordered nothing but broth — or an avalanche of toppings. Even Google Lens may struggle here.
• Pro tips: Multilingual touchscreen machines are becoming more common, but for the older button-style machines, share this trick: the top-left button is almost always the most recommended menu item. It also helps to know the basics of ordering ramen — much like choosing how you want your steak cooked, you can customize the noodles and broth:
  • Noodles: Choose your firmness → firm / regular / soft
  • Broth: Choose richness and oil level → rich / regular / light; more oil / regular / less oil
