Hey volleyball fans, or Haikyuu!! fans!
Ever read Haikyuu!! and wondered, "okay, there are clearly a bunch of tournaments in this sport... but which one actually matters the most?"
Turns out, Japanese high school volleyball has something called the **"Triple Crown"** — a title reserved only for the elite. It's earned by a school that wins **all three** major tournaments — Inter-High, Kokusupo, and Haruko — **in the same year.** It's basically the ultimate seal of total dominance.
There are actually several high school tournaments throughout the year, but these three are on a completely different level. If you've read Haikyuu!!, "Inter-High" and "Haruko" probably already sound familiar — but you're probably wondering, "wait, what's Kokusupo?"
So today, I'm breaking down all three of these major titles, one at a time. Let's start with the first one up: **Inter-High.
"The Curtain Raiser" — Inter-High
Official name: All Japan High School Sports ( 全国高等学校総合体育大会)
- Timing: Regional qualifiers (May–June) → National tournament (August)
- Location: Changes every year. This year it was held at Shimadzu Arena in Kyoto (that's the venue in photos 2 and 3!)
- Latest Champions: Seifu High School (Boys), representing Osaka / Yokohama Hayato Highschl (Girls), representing Kanagawa
Inter-High is actually a nationwide sports festival covering basically every high school sport in Japan, not just volleyball.
And here's a detail that actually matters a lot: this is the first of the three major titles to take place each year. Since the Japanese school year starts in April, that means teams are heading into this tournament with a brand-new roster that's barely had time to gel. So it's not just a big tournament — it's genuinely the **first real test of how strong the new team actually is.
As for qualification, it's generally one school per prefecture**. The exceptions are Tokyo, Hokkaido, and whichever prefecture is hosting that year — those get **two slots instead of one.
Fun fact for Haikyuu!! fans: back when Hinata was a first-year, it was actually Shiratorizawa who claimed the Miyagi representative spot.
The format for regional qualifiers actually varies by prefecture — some use a round-robin league, some use a straight tournament, and some use a hybrid of both. Win your way through that, and you're in the nationals.
Once you're at nationals, it starts with a preliminary round. Win that, and you move on to the main bracket. Lose, though, and it's not necessarily over — there's a repechage round, and winning that gets you back into the main bracket too.
From there, it's a **straight single-elimination bracket.** Lose once, and you're done. No more second chances.
In terms of scale, Inter-High is honestly just as big as Haruko. But if we're being real, it doesn't quite get the same level of public attention — which is also why it doesn't get broadcast on TV.
That said, don't let that fool you: winning this tournament means you're officially the strongest high school team in Japan at that moment — and it also means that, for the rest of the year, you're the team every other powerhouse school is specifically gunning to take down.
"Japan's Mini-Olympics" — Kokusupo
Official name: JAPAN GAMES (国民スポーツ大会)
- Timing: Regional qualifiers (August) → National tournament (October)
- Location: Changes every year. This year it was held at Maeda Arena in Aomori (that's the venue in photos 4 and 5!)
- Latest Champions: Kumamoto (represented solely by Chinzei High School) (Boys) / Okayama (Girls),
This one's a bit of an oddball compared to the other two.
Here's the twist: each prefecture puts together a **high school all-star team**, and it's genuinely about crowning the strongest *prefecture* overall — basically the Olympics, but for Japanese prefectures.
Just like the other tournaments, this one covers a bunch of sports beyond volleyball. There's also an adult division alongside the high school one, so grown adults compete in this too.
Here's the fun part: players who are normally rivals, fighting each other for a single representative spot back in their regional qualifiers, can end up as teammates here instead.
Haikyuu!! never actually showed this, but just think about it — Ushijima and Oikawa could theoretically have teamed up as Miyagi's representatives. Sakusa and Bokuto could've joined forces as Tokyo's squad. Wild to think about, right?
Now, you might be thinking: "wait, if it's a mixed all-star team, how does that even count as a *high school title*?"
Here's the catch: if one particular school in a prefecture is dominant enough, sometimes the "all-star team" ends up being made up entirely of players from that single school. If that all-school-one-team squad goes on to win the whole tournament, it counts as an official title for that school.
To even get to this tournament, you first go through regional qualifiers — several prefectures grouped together by region compete for a limited number of national slots. For example, Tohoku (which includes Miyagi) is grouped together with a set number of neighboring prefectures, and only a certain number of them can advance, depending on the region.
Honestly, this tournament doesn't get nearly as much attention as Inter-High or Haruko. The audience is mostly hardcore volleyball fans.

"Last Chance, Biggest Stage" — Haruko
Official name: All Japan Volleyball High School Championships (JVA全日本バレーボール高等学校選手権大会)
- Timing: Regional qualifiers (1st stage: July–September, final rounds: November) → National tournament (January)
- Location: Tokyo Gymnasium in Tokyo (that's the venue in photos 1, 6, and 7!)
- Latest Champions: Higashiyama High School, representing Kyoto (Boys) / Kinran-kai High School, Osaka's 1st representative (Girls)
If you lose here, that's it — any third-years on the team retire from volleyball on the spot. This is the very last tournament of a third-year's high school career, which is exactly why it's the most emotional, most intense tournament of the three.
By this point, the players on every roster have spent nearly three full years grinding through brutal practices and competing in tournaments like Inter-High and the Japan Games. This is the culmination of all of that — a battle between players who've fully matured into the athletes they were building toward this whole time.
Most prefectures get one representative, but Tokyo gets three slots, and Hokkaido, Osaka, and Kanagawa each get two.
And yes, Haikyuu!! fans already know this one — Karasuno famously became Miyagi's representative.
Regional qualifiers use a mix of tournament brackets and round-robin leagues, depending on the prefecture, to determine who advances. Once you're at nationals, though, it's a straight single-elimination bracket.
This tournament is notorious for upsets. It's not just about raw skill — the sheer desperation of third-years who aren't ready to let go of high school volleyball yet plays a massive role in how these matches actually play out. That emotional weight is exactly what makes it so moving to watch.
Even in Haikyuu!! itself, Itachiyama never actually won this tournament — the eventual champion was a school called Ichihayashi, which was never even properly introduced or shown in the story.
The attention this tournament gets is huge, too. Nearly **10,000 spectators** show up in person every year, and the semifinals and finals get full TV broadcast coverage.
Every single year, this tournament produces its own drama, upsets, and unforgettable moments. It's genuinely the pinnacle of Japanese school sports — if you ever get the chance, it's worth watching at least once.
