1) When to Go (Season-by-Season)

• Summer (Jun–Aug): Rainy early summer; festivals (matsuri), fireworks, beach escapes (Okinawa). Air-con everywhere, but pack light fabrics.
• Autumn (Sep–Nov): Comfortable temps, famous foliage (Kyoto, Nikko, Hakone). Ideal for first-timers.
• Winter (Dec–Feb): Powder snow in Hokkaido/Nagano, onsen towns (Hakone, Kusatsu). Illuminations in big cities.

2) Money & Payments (KRW ↔ JPY)

• Cash vs Card: Cards are widely accepted in chains, hotels, and transport hubs, but carry some cash for small eateries, shrines, markets.
• Where to Exchange: Competitive rates at KEB Hana/major Korean banks before departure or 7-Bank/JP Post ATMs in Japan (often better than airport counters).
• ATMs: Look for 7-Eleven (Seven Bank), Japan Post, and Lawson ATMs—reliable for foreign cards.
• IC/Transit Cards: Load cash onto Suica/PASMO/ICOCA; use for trains, buses, convenience stores, some vending machines.
• Tipping: Not customary; a polite thank you is enough.
• Budgeting Roughly (per day, excluding shopping):
  • Backpacker: ¥7,000–¥10,000
  • Comfort/Mid: ¥12,000–¥20,000
  • Upscale: ¥25,000+

Pro move: Bring a chip-enabled credit card and one backup. Notify your bank you’re traveling to Japan.

3) Where to Stay (First-Timer Friendly)

• Subways & JR Lines: Clear signage; English displays common in big cities.
• Shinkansen (Bullet Train): Fast intercity moves (Tokyo-Kyoto ~2h15m). Consider regional JR passes if you’ll ride multiple long segments.
• Buses & Taxis: Buses great in Kyoto/local towns; taxis accept card increasingly—line up at marked stands.
• Driving: Only if heading to rural Hokkaido, Okinawa beaches, or remote onsen areas; check international driving permit rules.

Hunting “Old Shops” (老舗 / しにせ) Without a List

If you love storied eateries but don’t want to chase exact addresses, look for:

• Wooden façades, noren curtains, low signage.
• Words like “創業○年” or “老舗” on menus/plaques.
• Shotengai (arcade streets) and yokocho (alley clusters) near old districts (e.g., Asakusa in Tokyo, Pontocho in Kyoto, Shinsekai in Osaka).
• Depachika (department store basements) for heritage confectioners and bento counters.
  Ask hotel staff for a nearby “shinisé” soba-ya or unagi-ya—you’ll get a local gem.

6) Experiences for First-Time Visitors

• Temples & Shrines: Senso-ji (Tokyo), Fushimi Inari (Kyoto), Meiji Jingu (Tokyo), Kiyomizu-dera (Kyoto).

8) Connectivity: eSIM Basics (No Store Runs, No Plastic)

• What is an eSIM? A digital SIM you install by scanning a QR—no physical card.
• Why for Japan? Immediate activation upon landing, strong network coverage, and easy top-ups.
• Korean travelers love it for seamless transfers (ICN/GMP → HND/NRT/KIX/FUK) and zero roaming shock.

Which Plan Should I Get?
Choose by trip length and data habits (video vs. maps/chat):

Thinking beyond Japan? Pick a regional/multi-country Voye plan if your route includes Korea-Japan-Taiwan-Hong Kong or Southeast Asia.

9) Culture & Etiquette (Comfortably Polite)

• Greetings: Light bow or nod; handshakes are fine with foreigners.
• Trains: Quiet voices, priority seats for those in need, no open eating on local trains (Shinkansen bento is okay).
• Shoes: Off at ryokan rooms, certain restaurants, and homes—look for slippers.
• Trash: Few public bins; carry a small bag.
• Cash tray: Place/receive money via tray at registers.
• Photos: Ask before photographing people or in small shops/temples.
• Language: Simple English works in tourist zones; basic Japanese phrases help. Many signs have Korean too in bigger cities.

10) What to Expect (Realistic First-Timer Notes)

• Compact rooms: Business hotels are small but efficient.
• Lines: Popular eateries/attractions may queue; mornings are your friend.
• Luggage forwarding: “Takkyubin” can send suitcases between hotels—travel light on trains.
• Weather swings: Layers help in spring/autumn; summer is humid; winters can be dry and cold.

11) Korean-Specific Tips

• Power: Japan uses Type A plugs, 100V. Bring a Type F→A adapter; most phone/laptop chargers are 100–240V (check your brick).
• Roaming vs eSIM: Avoid bill shock; a Japan eSIM is simpler and cheaper than roaming packages in most cases.
• Food comfort: Many Japanese flavors feel familiar (rice, soups, grilled meats) with countless new tastes to try.
• Visa/entry: ROK passport holders have traditionally enjoyed short-stay, visa-exempt entries; always confirm current rules with official sources before you book.

12) Packing Essentials

• Lightweight layers, compact umbrella
• Comfortable walking shoes
• Small towel/handkerchief (useful year-round)
• Reusable bottle (fountains abound in parks/stations)
• Universal adapter (Type A), portable power bank
• Onsen kit: quick-dry towel, modest swimwear for mixed facilities (if applicable)
• Copies of bookings, IC/credit cards, a bit of cash

14) FAQs (Short & Useful)

1. Do I need cash in Japan?
   Yes—carry some for small eateries and shrines. Cards work broadly in cities.
2. Which eSIM plan should I choose?
   Match data to your habits and trip length (see table above). Most first-timers do well with 8–15 GB for 10 days.
3. Will my phone work with eSIM?
   Most modern iPhones/Androids support eSIM. Check your device settings for “Add eSIM.”
4. Can I hotspot with a Japan eSIM?
   Yes, if your plan allows tethering (Voye plans typically do). Check the plan details.
5. Is English enough?
   In major areas, yes. Translation apps and simple Japanese phrases help elsewhere.
6. JR Pass or point-to-point tickets?
   For Tokyo-Kyoto-Osaka only, point-to-point often wins. For wider roaming (Tohoku/Hokkaido/Kyushu), evaluate regional passes.
7. Do I tip?
   No. Exceptional service is standard; tipping isn’t expected.
