Croatia Turns the Entire Adriatic Coast Into a Free Gym Every Summer. Japan Turns a Six-Minute Radio Broadcast Into a National Fitness Ritual Every Morning.

🇭🇷 Croatia 🇯🇵 Japan By Suki Nakamura, Out of Office

Croatian fitness culture, for about five months of the year, barely resembles fitness culture at all — it looks like an entire nation deciding the sea is a gym, a therapist, and a social club simultaneously, and acting accordingly. You'll see grandmothers doing genuinely serious open-water swims off Split's Bačvice beach at 7am, teenagers cliff-diving with alarming casualness, and a general national fitness level that seems to have been achieved almost entirely by osmosis, through proximity to water, rather than through anything resembling a structured programme. Japan's approach could not be a starker contrast: rajio taiso, a set of standardised calisthenics routines broadcast on national radio since 1928, performed in unison every morning by schoolchildren, office workers, and elderly community groups in parks across the country, to the same tinny piano recording several generations have now grown up with. One country's fitness culture is improvised, oceanic, and essentially free. The other is choreographed, communal, and running on a script nearly a century old.

I've swum badly off the Croatian coast trying to keep pace with a seventy-year-old woman who lapped me twice. I've also stood, deeply self-conscious, in a Tokyo park at 6:30am attempting to follow rajio taiso arm movements that every single other person present had clearly known since kindergarten.

Croatia: The Adriatic as an Unofficial National Gym Membership

There's no need for a formal gym culture to flourish in Croatia the way it has elsewhere, because the country's geography has essentially done the work for free — a dramatic, clean, swimmable coastline running the entire length of the country, with a swimming and open-water culture so deeply embedded that Croatia has produced a wildly disproportionate number of elite water polo players and swimmers for a country of under four million people. Early morning sea swims are a genuine daily ritual for a huge cross-section of coastal residents, not a wellness trend — you'll find informal groups of regulars, often spanning several generations, swimming the same stretch of coast at the same hour every single day, rain or shine, well into their seventies and eighties.

Formal gym culture does exist, particularly in Zagreb and other inland cities where the sea isn't a daily option, but it sits comfortably alongside a huge, thriving culture of free outdoor exercise — public parks across Croatian cities are dotted with vanjski fitness installations, basic but functional outdoor gym equipment installed by municipalities specifically to make movement accessible without a membership fee. Combined with an enormous popular enthusiasm for casual football, cycling, and hiking (Croatia's Plitvice and coastal trail networks are genuinely built for regular use, not just tourists), the overall picture is a country where fitness is woven into ordinary daily geography rather than cordoned off into a separate paid activity you have to schedule and travel to.

Japan: A Century-Old Broadcast Ritual That Still Gets an Entire Country Moving

Rajio taiso occupies a strange and wonderful place in Japanese culture — a standardised three-minute calisthenics routine, broadcast on NHK radio (and now, for the modern generation, also on TV and YouTube) at the same time each morning, performed identically by schoolchildren in summer holiday programmes, factory workers on shift breaks, and elderly community groups gathering in local parks, all moving through the exact same sequence of stretches and arm swings that's remained essentially unchanged since it was introduced in 1928. It sounds twee described from outside. Experienced in person, in a Tokyo park at dawn with forty strangers moving in perfect, silent unison to a piano recording several generations deep in cultural memory, it's genuinely moving — a form of collective, wordless solidarity that requires zero equipment, zero membership fee, and zero small talk.

Beyond rajio taiso, Japan's broader fitness culture reflects the same underlying values: restraint, quiet focus, and communal consideration over individual display. Gyms tend to enforce strict etiquette — wiping down equipment meticulously, no grunting, no phone calls, strict indoor-shoe rules — that can feel almost severe to newcomers used to louder Western gym cultures, but reflects a consistent national instinct toward not imposing your presence on shared space. Municipal taiikukan (community sports centres) are heavily subsidised and genuinely multi-generational, used by everyone from toddlers in swim lessons to retirees in gentle aerobics classes, reinforcing fitness as public infrastructure rather than a private, individualised pursuit you purchase access to.

The Verdict

Croatia's fitness culture is geographic and improvised — hand the country a coastline and a few outdoor gym bars, and its citizens will build an entire wellness ecosystem for free, on their own schedule, without a single instructor. Japan's is institutional and ritualised — a nearly century-old broadcast still gets strangers moving together at dawn with a discipline no gym membership could enforce. I love the freedom of the Croatian model, but I'm quietly obsessed with the Japanese one, because there's something genuinely rare about a fitness culture that asks nothing of you except showing up at the same time as everyone else and moving your arms exactly the way your grandparents did.

What Nobody Warned You About

r/croatia — paraphrased: tried to keep up with the regular morning sea-swim crowd on a first attempt, badly underestimated the distance and the current, had to be gently but firmly told by a local to start with a much shorter route.

Internations Tokyo — paraphrased: joined a gym expecting a standard membership, was surprised by an upfront "key money" deposit and paperwork that took nearly as long as opening a bank account.

Quora — paraphrased response on rajio taiso: it looks simple on video, but the actual muscle memory locals have from decades of repetition is obvious the first time you try to follow along in person and are noticeably a beat behind everyone else.

Conclusion

Somewhere between an unplanned 7am sea swim off the Croatian coast and a perfectly synchronised arm-swing in a Tokyo park, you'll realise fitness culture says more about a country's relationship to collective life than to individual vanity. Croatia trusts its geography to do the organising. Japan trusts a shared ritual, unbroken for generations, to do it instead. Show up to either one without ego, follow the regulars' lead, and expect to be visibly, briefly, the worst person there — everyone else has had decades of practice you haven't.
