国内のピックルボール競技人口は約33万人、まだ始めていないが関心を持つ「潜在層」は1189万人――ピックルボールワン（東京・千代田区）が約3万人を対象に実施した市場調査でこの推計がまとまった（2026年4月21日にプレスリリースとして公表）。競技人口の36倍という潜在層の大きさが話題を集めたが、市場参入や事業展開を考える立場では、別の数字がより実践的な示唆を与える。現役テニス経験者の72.5%がピックルボールに関心を示した、という一点である。
A market the survey shows to be "low awareness, high interest"
調査によると、ピックルボールの認知率は13.1%にとどまる。調査した11競技の中では9番目で、まだ広く知られたスポーツとは言えない。それでも競技人口は前年の約4.5万人から約33万人へと大きく伸びた。認知度は低いままだが、知った人の関心の高さに合わせるように、競技人口は前年比7倍近く増えた計算になる。潜在層1189万人という数字は、この「知られていないのに、知れば強く反応する」構造を裏づけている。
So far this is the market as a whole. But gazing at 11.89 million as one lump doesn't easily translate into moves for those building facilities or selling equipment. Only by pinpointing who among the 11.89 million moves first can you decide the order of investment. The clue lies in the survey finding that interest changes in stages with tennis experience.
Interest was proportional to the "depth of tennis experience"
The survey breaks interest down by how respondents relate to tennis. Among those currently playing tennis, 72.5% expressed interest, while it was 30.5% for those who played in the past, 26.1% for those with only trial-level experience, and 12.6% for those with no tennis experience at all. A clean gradient emerges: the closer to tennis, the higher the interest.
What this gradient means is that pickleball has a far shorter path in "pulling in sideways the crowd that already knows the fun of hitting a ball back and forth with a racket" than in "digging up total beginners from scratch." Rather than viewing the 11.89 million latent players flatly, ignite first from the tennis-leaning crowd. Whether you can grasp this order changes both facility utilization and the initial velocity of equipment sales.
Why tennis players shift over easily
The reason isn't the equipment or the venue—it's muscle memory. Stepping sideways to return an incoming ball, reading the exchanges at the net, calling out with your partner to take up position—these movements carry over almost intact from the feel built in tennis. Unlike a sport learned from zero, being able to "get into a rally" from the first session is huge. There's a foundation that makes interest more likely to translate into continued play.
On top of that, there's a thick layer of tennis players who have drifted away from the court with age—people for whom hard footwork and the strain of serving grew tough, who wanted to keep playing but found it hard to. Pickleball, with its smaller court and gentler ball speed, fits neatly into that gap of "want to hit it out, but tennis is physically heavy." The high interest is not mere novelty; to a large extent it's serving as a catch basin for a crowd that had been looking for a way out.
Indeed, the survey lists tennis courts (37.9%) as a place to play, second to public gymnasiums (49.5%). Nearly 40% already hit on tennis courts. For tennis players, it means being able to start a new sport at a familiar place. The psychological hurdle is even lower.
The relationship between tennis experience and interest
| Relationship with tennis | Interest in pickleball |
|---|---|
| Currently playing | 72.5% |
| Played in the past | 30.5% |
| Only trial-level experience | 26.1% |
| No tennis experience | 12.6% |
The economics of "conversion" that pay off for Japan's facility business
The fact that the tennis crowd moves lightens facility-side investment decisions. A pickleball court is 13.4m × 6.1m, close to the size of a badminton court. Multiple pickleball courts can be drawn into the space of one tennis court, so an existing tennis facility can generate new usable hours by simply adding lines with minimal extra investment. Compared with securing land from scratch and building dedicated courts, both the upfront cost and the payback risk are on an entirely smaller scale.

The equipment business can target "switching demand"
The implication for the equipment side is clear too. Tennis players are a crowd that already has the habit of paying for gear, with little resistance to allocating a certain budget to rackets and shoes. This differs in both unit price and replacement frequency from total beginners who start with a few-hundred-yen starter set. The 72.5%-interest crowd can become, as is, the initial demand for an equipment market of "buying a decent paddle from the start."
This read is consistent with the way prestigious tennis brands are shifting their footing to pickleball one after another. It's because they can carry over the customer base and distribution cultivated in tennis. In Japan too, major sports makers are beginning to enter, and simply placing pickleball equipment next to the tennis aisle creates a path into the field of view of experienced players.

Rather than chasing figures, grasp the ignition point
The figures of 11.89 million and 36x show the height of the market's ceiling, but on their own no one can move. The value of this survey lies in drawing an "entrance map" where the depth of tennis experience and interest line up cleanly in proportion. Rather than waiting for the whole latent pool, first take aim at the current and former tennis crowd. Facilities start from converting existing courts; equipment starts from switching demand. The low awareness of 13.1% means, flipped around, that a market where "whoever grabs the ignition point first can run the longest" still lies untouched.
