What kind of people are the coaches of Japan's national ski team, and what kind of work do they do? We would like to delve into this topic, which is rarely covered even in specialist magazines. In this first of two articles, we spoke with Yuta Shiro, head coach of the Japanese mogul team, who is expected to win a medal at the Milan-Cortina Olympics. First, we would like to focus on the highly responsible role of the head coach and how the workload is shared
The head coach acts like a manager of the team
"The job of a national team coach is not just to provide technical guidance. It is a wide-ranging job."
In a team that includes underage players, the coach is expected to provide guidance, responsibility, and supervision
"As head coach, I'm in a position to manage the team. In business terms, it's like being a manager. I manage the budget and think about the overall strategy."
Managers are always expected to improve performance, and if any problems occur, they are held responsible. Coach Shiro, who we spoke to this time, was active as a player in the 2000s and has a wealth of experience as a coach
He became head coach in the 2018-19 season and is the backbone of the Japanese mogul team, having participated in the past three Winter Olympics: Sochi, Pyeongchang, and Beijing
"When we go on overseas expeditions, I determine the best schedule and make the necessary preparations. Arranging flights and accommodations is also my job.
Furthermore, selecting and appointing other coaches and trainers is an important part of my work, and I'm also responsible for gathering the opinions of the coaches when creating various standards and submitting them to the competition headquarters."
In professional baseball teams and J.League clubs, there is a manager above the head coach, and above the manager or someone with a similar role.
However, in the case of the national ski team, the head coach essentially doubles as the manager and GM.
"Ultimately, we discuss and decide with the relevant director of the Ski Association of Japan (SAJ), but whatever the event, the head coach's decision is respected and is generally adopted."
Coaching staff with various roles
Currently, the national freestyle moguls team is made up of S-rated athletes Horishima Yukimasa, who won the 2025 World Championship moguls, Tomitaka Hinako, who came in second in the same moguls, and Yanagimoto Rino, who came in third overall in the 2025 World Cup dual moguls, with A-rated and B-rated athletes below them making up the top team
In addition, there are about 30 players in the development category, designated D. In order to participate in the Olympics, World Championships, World Cup, etc., in principle, players must be certified as SAJ's designated training players, in other words, they must join the national team
Supporting this huge pyramid is the coaching staff
In addition to the head coach, there is one chief coach and five technical coaches, as well as a secretary, doctor, physiotherapist, strength coach, and nutritionist, all of whom contribute to the team in their respective areas of expertise
"In the case of moguls, the workload for the head coach is extremely heavy. That's why I have a secretary who supports me with the practical work. However, I don't just hand over all the detailed tasks to the secretary.
For example, only I can decide the schedule for overseas trips. Sometimes a competition is canceled due to insufficient snow, leaving a gap in the schedule until the next competition.
In that case, I have to decide whether to stay on-site or return to Japan."
Therefore, once the specific details have been decided to a certain extent, the secretary will arrange tickets and accommodation through SAJ's partner company, JTB."
A secretary's job is not just to arrange air tickets and accommodation
"Because the team and players receive support from the government, the secretary is also responsible for the administrative matters. The secretary covers the parts of the work that I cannot handle."
The chief coach's role is to solidify the foundation
The chief coach is the person whose name is next in line to the head coach on the roster
The current coach in charge of this role is Shigeru Kobayashi, the oldest member of the team and a former national team athlete. With his trademark long mohawk hair, he was known as "Mohawk Kobayashi" and was a familiar face on TV ski programs in the 1990s
He has a long history as a coach of the national team, and was acquainted with Nagano Olympic gold medalist Satoya Tae and World Cup and World Championship winner Uemura Aiko during their active playing days
"The chief coach is in a position to bring the coaching staff together. Coach Kobayashi is a very reliable person with extensive experience both as an athlete and as a coach, and I have consulted with him on many things.
I participated in all three Olympics with Coach Kobayashi. Rather than directly strengthening the national team, his role is to strengthen the system for athletes to join the national team, including nurturing excellent coaches in various regions."
In other words, he is someone who works not only for the national team, but also for the base of the pyramid below it, and works on a total basis to make the foundation solid. Coach Jo emphasizes that this aspect is important in order for Japanese mogul skiers to become even stronger
"Soccer coaches need licenses, right? No matter how skilled a coach is, they can't become a coach without a license.
In contrast, the ski federation as a whole, not just in mogul skiing, doesn't have a fully established coaching licensing system. So, we're currently working with JSPO (*1) to create a coaching qualification. In the future, we believe there should be more qualified coaches. When that happens, I think the role of the chief coach will become even more important."
*1 = Abbreviation for the Japan Sport Association, a public interest incorporated foundation that runs the National Sports Tournament and other events, as well as the certified sports instructor (coach qualification) system
Moguls is a relatively new sport. It was made an official Olympic sport in the 1990s, so it is still a young sport. Compared to 20 years ago, the training and development system is quite mature. However, Coach Jo believes that it is still in the development stage and needs to be further improved
Why the head coach is absent
Coach Shiro has been in charge of on-site leadership as head coach since the 2018-19 season, but since last season he has taken a step back and not accompanied the team on overseas tours
"Actually, I suffered an injury, and one of the reasons is that it hasn't fully recovered yet. I will be participating in meetings online and providing support from Japan throughout the Olympic season.
Five technical coaches will be going to the competition venues, and among them, I have asked Coach Shimatani to take on the on-site management duties that I previously handled."
Looking at it from another perspective, the Japanese team can compete at the Olympics even if Coach Jo is not there. This shows that they have the strength to do so
Olympic gold medalist coaches Japan team
A technical coach, who is in charge of the field, is literally a technical instruction coach.
Systematically, the coaches do not instruct everyone uniformly, but rather provide individual instruction. Coach A instructs players B and C, Coach D instructs players E and F, and so on.
"While I was working as head coach, I also provided technical guidance to specific athletes up until the Beijing Olympics. Shimatani Hiroyuki, Endo Hisashi, and Janne Lahtera were all members of the team from the Beijing Olympics onwards."
Coach Hiroyuki Shimatani has competed in international competitions since the mid-1990s and has a long history of coaching moguls.
Coach Takashi Endo placed 7th at the Vancouver Olympics and has also been on the podium at the World Cup. He was the ace of the Japanese men's team before Yukima Horishima and is still close to being an active athlete.
Finnish coach Janne Lahtella won a silver medal at the 1998 Nagano Olympics and a gold medal at the 2002 Salt Lake City Olympics. He was a world-class athlete with many World Cup victories.
The Japanese team has been inviting coaches from overseas since the 1990s, but Janne Lahtella is the biggest name among them, and it is noteworthy that his skills and experience are being poured into the Japanese team. And in recent years, the team has further strengthened its coaching staff.
"The Japanese team has many players who will be competing in the World Cup, so to ensure that the instruction given to each individual player is not diluted, we added coach Taniguchi Takeho last season and coach Tateda Shunya this season. This season is also the Olympic season, so these two new coaches will also accompany us on overseas tours
At the time of the Beijing Olympics, Shimatani and Endo had just become coaches for the World Cup team, so they accompanied the team full-time to increase their experience. Now, Taniguchi and Tateda will also be experiencing the Olympics, which will surely increase their experience as coaches. It's still a long way off, but I hope that by the 2030 Olympics, the two of them will be able to lead the team."
Coach Jo's decision to step back is also intended to foster the development of younger coaches, who will gain experience playing in big overseas games, which will be an asset to the entire team
