“We have to find our own style of Waterpolo based on our potential” – Yoshinori Shiota on adapting the Game

In this episode of the Waterpolo Expert Talk, Yoshinori Shiota,
head coach of the Japanese men’s national water polo team, explains
why long-term success in international water polo is only possible
when teams build their game around their own strengths, rather than
copying traditional European models. Yoshinori begins by making an
important clarification: the current Japanese playing style was not
created by him, but by former head coach Yoji Omoto. In the years
leading up to the Olympic Games, Japan initially tried to follow a
more traditional European-style water polo, including heavy use of
the center forward and zone defense. Over time, it became clear
that this approach did not fit the physical profile of Japanese
players. Compared to teams from Hungary, Serbia or Croatia,
Japanese players are generally smaller and lighter. Instead of
seeing this as a weakness, Omoto and his staff decided to
completely rethink the concept of the game. The result was a
radical shift in philosophy: press defense, passing-lane defense
and constant counterattacks became the foundation of Japan’s
identity. Yoshinori explains that for Japan, scoring in a static
six-on-six offense is extremely difficult. The team’s real
advantage lies in speed, agility and flexibility. By swimming more,
creating chaos in passing lanes and attacking before defenses are
set, Japan can compete with physically stronger opponents. This
philosophy requires tremendous fitness, discipline and collective
understanding, but it allows Japan to stay competitive at the
highest level. Over time, the system has continued to evolve. While
press defense remains the base, Yoshinori now emphasizes the
importance of being more tactically flexible. Against different
opponents – such as Hungary, the USA or European teams with strong
center play – Japan must be able to adjust. Zone defense, hybrid
systems and situational tactics are now part of the playbook. A key
message of the episode is adaptation. Yoshinori stresses that you
cannot play someone else’s game if you do not have the same player
material. Coaches must be honest about their squad’s
characteristics and design a system that maximizes existing
strengths instead of exposing weaknesses. The conversation also
touches on Yoshinori’s personal coaching journey. After more than
ten years as a Japanese national team player, he pursued academic
studies in coaching, worked at Nippon Sport Science University, and
later spent time in the United States with the US national teams.
Working alongside coaches like Dejan Udovičić influenced his
approach, particularly in the area of leg training and physical
preparation. Yoshinori highlights that leg strength is not only
crucial for goalkeepers, but for all field players in modern water
polo. While swimming speed is important, verticality, stability and
explosiveness are decisive factors in today’s game – an area where
Japan continues to invest heavily. Looking ahead, the episode
addresses Japan’s busy international calendar. With World
Championships in Fukuoka, Asian Games as Olympic qualification, and
further global tournaments ahead, Yoshinori sees the packed
schedule as a major advantage. Without a professional domestic
league, Japanese players are “hungry for games” and benefit greatly
from every international match. This episode offers a clear, honest
and insightful look at how modern water polo systems must be built
around identity, realism and adaptation – and why Japan’s path may
offer valuable lessons for many other nations. More about the
