Overseas Swimming Event: Cultural Experience and Technical Observations from the Okinawa Open-Water Swim in Japan

Introduction

There is a kind of swimming called “swimming in someone else’s sea.”

The waters of Okinawa and the waters of Taiwan are both blue, but when you swim in that water, the experience is completely different. The language is different, the culture is different, the organization is different, and even the pre-swim warm-up music for athletes is J-pop—these differences together form a unique “swimming abroad” experience.

My initial motivation for joining this open-water swim in Okinawa was simply “wanting to try swimming in a different sea,” but what I brought back was far richer than I expected.

Registration and Administration: The Meticulousness and Complexity of Japanese Events

The registration process for Japanese swimming events is the most meticulous I have ever encountered. The form requires you to fill in: emergency contact phone number (requiring a domestic Japanese number or an attached “international emergency contact method” explanation), self-assessment of swimming ability, insurance options, and food allergy declarations.

This level of detail was somewhat unfamiliar to me as someone from Taiwan, but at the same time, I could feel how much the organizers prioritize athlete safety. Behind every detail lies a corresponding safety consideration.

The Sea of Okinawa: Technical Observations

Okinawa is located at the southwesternmost tip of Japan, with water temperatures reaching 29-30°C in summer. The clarity of the water is astonishing—while swimming, I could clearly see coral reefs 8-10 meters below the surface. The psychological effect of that visibility is very positive: when you can see the bottom, you don’t fear the depth.

In terms of currents, the sea currents in Okinawa are more regular than those in Taiwan’s Penghu area. Unlike the unpredictable lateral currents of the Taiwan Strait, they are easier to predict and compensate for.

Technically, the biggest lesson from the Okinawa event was observing the swimming style of Japanese athletes:

• Slower but more complete stroke cadence: Japanese open-water swimmers generally have a lower stroke rate than Taiwanese swimmers, but each stroke covers a longer pull distance, resulting in greater overall efficiency
• Fewer breathing exchanges: Many athletes breathe only every three to four strokes, with extremely efficient breathing technique
• More precise turning technique: The radius around the buoy is very small, almost “hugging the buoy” through the turn, far more efficient than the wide arcs I commonly see Taiwanese swimmers take

Cultural Experience: Japanese Details in a Swimming Competition

The details of the Japanese event left a deep impression on me:

The Ultimate Expression of Punctuality Culture

The event schedule was precise to the minute, with every wave’s start time executed exactly as planned. Fifteen minutes before the start, the announcement said “All athletes in this group, please take your positions”; at 10 minutes, “Starting soon”; at 5 minutes, “Check your equipment”; at 1 minute, “Get ready.” This level of precision is quite rare in Taiwanese events (including the many I have participated in).

The Thoughtfulness of Aid Stations

The aid stations weren’t just a few bottles of sports drink on a table. There were staff members handing out supplies, a designated order for taking items (to prevent athletes from crowding together), and backup supplies for athletes at the back of the pack. The food after getting out of the water included Okinawan specialty purple sweet potato candy, hot tea, and a traditional mochi whose name I couldn’t even pronounce.

The Culture of Respect Among Athletes

In the water, when Japanese athletes bumped into you, many would nod in acknowledgment during lulls (such as when resting against the buoy line). That atmosphere of “maintaining courtesy even during competition” is something I have rarely experienced at Taiwanese events.

The Fun and Challenge of Language

Not speaking Japanese was more troublesome than expected during the race, but also more interesting:

• At check-in, I managed with Google Translate and hand gestures, and the staff were extremely patient
• I couldn’t understand the announcements, so I could only watch the Japanese athletes around me and follow their actions (which worked surprisingly well)
• I “conversed” with a Japanese athlete next to me at the aid station, relying entirely on facial expressions and thumbs-up, and somehow we conveyed complete encouragement

The language barrier made me more observant of my surroundings and others than usual, which actually created a peculiar state of focus.

Observations and Changes I Brought Back to Taiwan

This trip to Okinawa brought back several concrete changes:

• Adjusting stroke cadence: I began practicing the completeness of each stroke rather than high-frequency, rapid stroking
• Breathing interval practice: Deliberately practicing breathing every four strokes in training to extend breathing intervals
• Turning technique drills: Making the radius around the buoy a key focus of training

The biggest change was psychological: Taiwanese events are familiar, and familiarity can sometimes be an obstacle to improvement. In Okinawa, everything was new, forcing my observation and learning abilities to operate at maximum capacity. That state carried back to Taiwan and sustained my training motivation for several months.

Practical Advice: Planning an Overseas Swimming Event

• Registration deadlines are usually much earlier than in Taiwan—act promptly once confirmed
• Prepare swimming ability documentation in English and Japanese (required by some events)
• Attach destination insurance certificates; Japanese events typically have strict requirements
• Choose travel insurance with “participation in sports competitions” as an additional coverage
• Arrive early to acclimate to the local waters; don’t wait until race day for your first swim

Conclusion

Swimming in the waters of Okinawa—that blue so clear you could see the coral reefs, and the Japanese athletes you didn’t know but who cheered you on with thumbs-up—formed a memory that is hard to fully replicate in words.

Swimming is not just a sport; it is a language. In any country, in any sea, when you dive in and swim, you begin a shared dialogue with that place. Okinawa’s sea, thank you for your hospitality.
