From Seoul to Tokyo: The Ultimate First-Time Travel Guide to Japan for Koreans

Visa-free entry, currency tips, cultural etiquette, and the power of staying connected with Voye Global’s eSIM

Seamless Travel from Korea to Japan Starts Here

With Korea and Japan separated by less than two hours of flight time, it’s no surprise that Japan is one of the top overseas destinations for Korean travelers. From the neon-lit streets of Tokyo to the serene temples of Kyoto, Japan offers an exciting blend of tradition, pop culture, and world-class hospitality.

And thanks to visa-free entry for South Korean citizens, it’s easier than ever to plan a spontaneous or short getaway.

But traveling between countries also means navigating different currencies, mobile networks, etiquette norms, and digital tools. That’s why using an eSIM—like those offered by Voye Global—is essential for staying connected and stress-free during your journey.

Visa-Free Entry from Korea to Japan

South Korean passport holders can enter Japan for up to 90 days without a visa for tourism, short business trips, or family visits.

What You’ll Need:

• A valid South Korean passport
• Return or onward travel ticket
• Proof of accommodation may be requested
• No vaccination certificates are required as of current guidelines (subject to change)

Tip: Use your Voye Global eSIM to access immigration instructions, hotel reservations, or embassy contact info online upon landing.

Currency Exchange in Japan

Japan uses the Japanese Yen (JPY). While Japan is increasingly card-friendly, cash is still king in many places—especially rural areas, smaller eateries, and traditional markets.

Currency Exchange Tips:

• Exchange KRW to JPY at Korean banks before departure for better rates
• ATMs at 7-Eleven and Japan Post Bank accept foreign cards
• Use mobile currency converter apps like XE or Currency
• Keep small denominations handy for trains, vending machines, and local cafes

With Voye Global’s eSIM, you can stay online to find the nearest ATM or track exchange rates in real-time without hunting for Wi-Fi.

Key Etiquette Tips for Korean Travelers in Japan

Respect Personal Space

Unlike Korea, where social closeness is common, Japanese culture values personal space and quietness in public—especially on trains.

Bowing Over Handshakes

Bows are the standard greeting. A slight bow goes a long way in showing respect.

Shoes Off Indoors

Be prepared to remove your shoes when entering homes, traditional accommodations, or certain restaurants.

Politeness Above All

Soft-spoken manners and apologizing for the smallest inconvenience are appreciated. Phrases like “Sumimasen” (Excuse me) and “Arigatou gozaimasu” (Thank you) are handy.
