Japan.

Japan runs its academic year April to March, so exchanges start either in April (spring) or late September/October (autumn), for one or two semesters. The pull is obvious: nowhere else combines this level of safety, food and sheer strangeness. You can eat brilliantly for €5, ride a train that's never late, and be hiking a volcano or standing in a thousand-year-old temple by the weekend.

It is not a soft option. English gets you surprisingly far in daily life but not all the way, the bureaucracy loves paper and stamps, and making local friends takes real effort. If you want a semester that genuinely reshapes how you see the world, and don't mind being politely confused for a month, Japan delivers like almost nowhere else.

University clubs, 'circles' (sakuru), are the heart of student life. There's one for everything: tea ceremony, snowboarding, anime, a cappella, futsal. Joining in your first two weeks is genuinely the best thing you can do, because Japanese students socialise through circles far more than through random nights out, and it's how you'll make actual local friends instead of only hanging with other exchange kids.

Nights out mean izakaya (cheap food-and-drink pubs), then karaoke until the trains restart around 5am, because they stop near midnight. Tokyo, Osaka and Fukuoka have proper clubbing; smaller cities lean cosier. Drinking is social and cheap with nomihodai (all-you-can-drink) deals, but people rarely get sloppy in public. Expect plenty of konbini beers by the river too.

Japan is cheaper day-to-day than most students expect: eating out often undercuts cooking, and a filling meal runs €4–7. The real sting is upfront housing costs and, in Tokyo, rent. Outside the capital, Fukuoka, Nagoya, Beppu, your money stretches a lot further.

Budget roughly €800–1,400 a month all-in depending on the city. Tokyo and Kobe sit at the top; Kyushu is kindest to your bank balance. Transport eats more than you'd think unless you're riding on a discounted commuter pass.

• Dorm or share-house room: €300–550/mo
• Food (conbini, cheap eats, some cooking): €200–300/mo
• Commuter train pass (teiki): €30–60/mo
• Phone SIM with data: €15–25/mo
• Izakaya + karaoke night out: €25–40

Most exchange students land in university dorms, cheapest by far (often ¥20,000–45,000/month, roughly €120–270), furnished, and no guarantor drama. Grab one through your host uni's housing office the moment you're offered a place; they fill fast. If dorms are full, foreigner-friendly share houses (Oakhouse, Sakura House, Borderless House) skip the brutal upfront fees and come with instant housemates.

Avoid private apartments unless you must: Japanese rentals often demand 'reikin' (key money, a non-refundable gift to the landlord), 'shikikin' (deposit), agency fees and a guarantor, stacking 4–5 months' rent before you even move in. A Tokyo 1K flat runs ¥70,000–100,000/month; share houses ¥45,000–70,000. Never wire a deposit to a 'landlord' you found on social media, book through a known agency or your university.

• Uni dorm, cheapest, easiest, book the second you're accepted
• Share house (Oakhouse, Sakura House), no key money, instant friends
• Private 1K apartment, avoid; huge upfront fees plus a guarantor

Get a rechargeable IC card (Suica or Pasmo in Tokyo, ICOCA in Kansai) on day one, one tap for trains, buses, konbini and vending machines. Then set up a 'teiki' commuter pass for your home-to-campus route; it's heavily discounted and pays for itself in weeks. Cities are dense and walkable, and a second-hand bike (¥5,000–10,000) is a student staple.

Intercity, the shinkansen is glorious but pricey, Tokyo to Kyoto is about ¥14,000 and 2h15. To travel broke, use overnight highway buses (Willer, ¥4,000–6,000), the seasonal Seishun 18 kippu (5 days of local trains for ¥12,050), or budget airlines Peach and Jetstar for the longer hops.

• IC card (Suica/ICOCA), tap for trains, buses and shops
• Commuter pass (teiki), big discount on your daily route
• Shinkansen is fast but expensive; overnight buses go cheap

Teaching leans lecture-heavy with real weight on attendance, miss too many classes and you can fail regardless of the exam. Grading is percentage-based (roughly 90+ = S/A, down to 60 to pass). Japan uses its own credit system: a typical semester course is 2 credits and a full load is around 14–16, which your home university will usually map to about 30 ECTS. Confirm the conversion in your learning agreement before you go.

English-taught options have grown fast. The Global 30 ('G30') programmes and university-specific English tracks mean you can do a full semester in English at the University of Tokyo, Kyoto University, Kobe, Nagoya and Kyushu (Fukuoka), plus Waseda, Keio and Sophia in Tokyo. Ritsumeikan APU in Beppu is roughly half international and fully bilingual, the softest landing if your Japanese is zero.

For a full semester you'll need a Student visa, and the reality depends on your nationality, but the shape is broadly the same. Your host university applies for a Certificate of Eligibility (COE) on your behalf inside Japan, which can take 1–2 months. Once it arrives, you take it to a Japanese embassy or consulate at home and they issue the visa, usually within a week and often free or cheap.

At the airport you're handed a Residence Card ('zairyu' card), carry it at all times. Within 14 days you must register your address at the local city hall and enrol in National Health Insurance (around ¥1,500–2,000/month, covering 70% of medical costs). Want a part-time job? Apply for 'permission to engage in activity other than that permitted' and you're cleared for up to 28 hours a week.

• Student visa needs a COE, your uni applies, allow 1–2 months
• Register at city hall and join health insurance within 14 days
• Work permit clears you for up to 28 hours/week part-time

You'll live off conbini (7-Eleven, Lawson, FamilyMart), genuinely good rice balls, hot food and coffee at all hours, plus gyudon chains (Yoshinoya, Sukiya) at ¥400–500, ramen, and teishoku set meals. Your campus co-op cafeteria (seikyo) is the cheapest hot lunch you'll find anywhere. Cash is still king in small places, so always carry some. Tipping doesn't exist here and can even come across as rude.

A few norms trip students up: take your shoes off indoors, don't eat while walking, keep quiet on trains, and sort your rubbish obsessively or your building manager will have words. Slurping noodles, on the other hand, is completely fine. The calendar revolves around festivals, hanami picnics under cherry blossom in spring, summer matsuri with fireworks and yukata, and a quiet, family New Year (oshogatsu).

Studcasa's Japanese exchange cities run from the mega-city buzz of the east to laid-back, cheap Kyushu in the south. Roughly: Tokyo for everything, Kansai (Kyoto/Kobe) for culture and beauty, and Kyushu (Fukuoka/Beppu) for value and an easy landing.

• Tokyo, the full-throttle option: most English-taught programmes, endless nightlife, priciest rents
• Kyoto, temples, tradition and a proper student town; bike everywhere, Osaka minutes away
• Fukuoka, Kyushu's food capital: cheap, sunny, ramen and beaches, gateway to Korea
• Kobe, cosmopolitan port between Osaka and Kyoto, hills-meets-sea, brilliant quality of life
• Nagoya, central and affordable, a handy base halfway between Tokyo and Kyoto
• Beppu, hot-spring town home to bilingual, half-international Ritsumeikan APU; the softest landing

Weekends are where Japan pays off. Base yourself anywhere and there's a temple, volcano, hot spring or beach within a couple of hours. The trick for a broke student is overnight buses, the seasonal Seishun 18 local-train pass, and budget airlines for the longer hauls, and Japan is close enough to South Korea that a passport trip is genuinely affordable.

• Kansai loop (Kyoto–Nara–Osaka), temples, bowing deer, street food; cheap on local trains
• Hiroshima + Miyajima, Peace Park and the floating torii, reachable by overnight bus
• Mount Fuji / Fuji Five Lakes or Nikko, the classic day trips out of Tokyo
• Seoul or Busan, South Korea: €80–150 return on Peach/Jetstar, especially from Fukuoka
• Hokkaido or Okinawa, save up for snow festivals or beaches via budget flights

Most rookie mistakes in Japan are admin and etiquette, not danger. Sort the boring stuff in week one and you'll glide; ignore it and you'll spend a month fighting paperwork and eating cold noodles.

• Get an IC card and set up your commuter pass the day you arrive
• Carry cash, loads of restaurants and small shops still refuse cards
• Learn hiragana and katakana before you fly; menus and signs suddenly click
• Join a circle (club) in your first fortnight, it's how you meet locals
• Open a foreigner-friendly bank account (Japan Post, Shinsei/SBI); get a hanko stamp if asked
• Sort your rubbish exactly as the schedule says, or expect a stern note on your door
