Men’s Rugby Can Japan Shock the World Again in 2027?

Japan’s Brave Blossoms have already proven they can defy rugby’s established order. Who can forget that stunning 2015 victory over South Africa? Or that quarter-final run as World Cup hosts in 2019? Both these events showed the world that Asian rugby belongs on the biggest stage.

However, as the countdown to the 2027 Men’s Rugby World Cup begins, there’s one question to consider: Can Japan pull off another shock against the sport’s giants?

The current odds would suggest otherwise. Yet recent history has shown that underestimating Japanese rugby can be a costly mistake. This guide looks at how Japan could potentially cause another shock at the next edition of the World Cup. 

Japan’s Legacy of Surprises 

Over the past decade, the Japanese national team has had a habit of being rugby’s great disruptors. Few fans of the spot will forget their incredible 2015 upset against South Africa. Described as the game’s biggest shock of all time, Japan were as high as 80/1 to topple the Springboks. The win against one of rugby’s biggest forces instantly entered World Cup folklore. 

Four years later, as hosts in 2019, Japan raised the bar again by reaching the quarter-finals. In getting that far, they defeated both Ireland and Scotland along the way. Those two achievements, while not regular occurrences, proved Asian rugby could compete against the world’s elite. It also sparked new levels of interest and investment across the region. 

Heading into 2027, that investment is unlikely to make an impression just yet. Nevertheless, Japan does carry the hopes of millions who believe another shock might be possible.

The Odds Are Stacked Against Japan 

When analysing the outright winner odds at Betway, it doesn’t look positive for Japan to lift the Rugby World Cup trophy in 2027. The club currently sits at a lofty 250/1 to go all the way. For context, traditional giants dominate the top of the betting: New Zealand (5/2), South Africa (11/4), and France (9/2) are considered the favourites. 

By contrast, Japan’s odds place them alongside Samoa (250/1) and behind Italy (200/1) and Wales (40/1). On paper, this gap reflects the size of the challenge. Although odds only tell part of the story. After all, few bookmakers expected Japan to stun South Africa a decade ago. 

Building the Next Generation 

Player development. For Japan to challenge again, this aspect is important. The launch of Japan Rugby League One has attracted international stars while supplying domestic players with higher-quality competition. This mix will hopefully pay off in the decades to come – but it could still give the Brave Blossoms a sharper edge by 2027. 

Key players like Kotaro Matsushima and Michael Leitch have already shown what Japanese rugby can achieve on the world stage. The next step: nurturing depth across the squad so that performances remain consistent against fellow Tier 1 nations. If that depth is gained, Japan could once again go deep in the World Cup. 

The Importance of Belief and Style 

What sets Japan apart from other rugby nations? One key factor is their fearless style of play. Their fast-paced, attacking approach has allowed them to outmanoeuvre physically larger opponents. In doing so, they can turn matches into contests of speed, accuracy, and fitness, which provides a more even playing field for Japan. 

This identity has also inspired players and fans alike, where the latter considering them to be one of the most exciting teams to watch. However, to shock the world again, belief will be just as vital as tactics. Rather than outmuscle the likes of South Africa and New Zealand, they’ll have to outthink and outpace them instead. 

Japan: Asia’s Rugby Flagbearers 

There’s no underselling how Japan’s rise has lifted the profile of rugby across Asia. While other current entrants, Hong Kong China faces even longer odds at 2,500/1, Japan has proven that progress is possible.

Success in 2027 wouldn’t only be another proud moment for Japanese fans. It would also be a victory for Asian rugby overall, one that would further inspire the next generation across the continent.
