September 30, 2026 — A sudden gap has emerged in Japan's national team defense. The Japan Football Association (JFA) has announced that Hayato Araki, a centre-back from Sanfrecce Hiroshima, has been additionally called up to the national team. He has been assigned jersey number 32. This is no ordinary announcement — behind it lies the collapse of an entire defensive unit.
Tomiyasu, who joined the squad in late August, was ruled out after suffering an injury in a league match. Following him, another defender, Ando, was unable to stay with the squad due to illness. Midfielder Kumasaka was also ruled out with an injury. Then on September 29-30, two more players left the squad — Henry Heroki Mochizuki (called up on the 29th, number 22) and Ryunosuke Sato (left the squad due to circumstances at his club).
In this situation, Japan will play friendly matches against Ecuador on October 1 and Panama or New Zealand on October 5. With five players absent, Japan's defense is being hastily assembled. This news item will quickly fade with time, but hidden within it is a deeper problem in Japanese football.
Who is Araki and why he matters now
Hayato Araki is a centre-back for Sanfrecce Hiroshima, a J-League club. He is one of the best defenders in Japan's domestic league. The biggest problem in Japan's defense right now is Tomiyasu's absence. Tomiyasu is not just a centre-back — he can play both full-back and centre-back, and his passing ability is the backbone of Japan's defensive build-up.
Araki, as a centre-back, can fill Tomiyasu's position. However, there is a difference in profile between the two. Tomiyasu has experience in Europe's top leagues and is adept in one-on-one duels against various attacking players. Araki is a J-League-based player with limited international match experience. How successful Araki will be against Ecuador's attacking players is currently uncertain.
The depth of the defensive crisis
Japan's defense is being assembled amid the absence of five players. Tomiyasu, Ando, Kumasaka, Sato, and one more — these five absences have come simultaneously. For a national team that trains only a few days apart, building defensive cohesion is the most difficult task. Defensive cohesion requires repeated training. Building a new defense from scratch means starting that cohesion anew.
Such situations are rarely seen in Japanese football history. Normally, the Japanese national team relies heavily on European-based players. But this time, with two centre-backs — Tomiyasu and Ando — absent simultaneously, Japan has had to rely on domestic league players. This could be a strength of Japanese football — the ability to quickly supply players from the J-League. But at the same time, it reveals a weakness — the depth of the defense is shallower than other positions.
Araki's opportunity and risk
This is a big opportunity for Araki. Getting a chance to play for the national team means an opportunity to prove his ability on the international stage. If he plays well against Ecuador and Panama/New Zealand, the chances of him securing a regular place in the national team in the future will increase. But there is also risk. Playing for the national team means playing under pressure. If Araki makes a mistake, he could be blamed for it.
For Sanfrecce Hiroshima, Araki playing for the national team is a matter of pride. But at the same time, it is also risky. If he suffers an injury in an international match, the club will suffer. And if Araki plays well, his market value will rise and foreign clubs will notice him.
Mochizuki's story
Henry Heroki Mochizuki is a player for FC Machida Zelvia. He joined the national team on September 29 and was assigned jersey number 22. Mochizuki is a midfielder. His call-up is an opportunity to test the depth of Japan's midfield.
This is an opportunity for Mochizuki to play for the national team. But at the same time, he too will play under pressure. For inexperienced players in the national team, handling such pressure is difficult.
The mystery of Sato's departure
Ryunosuke Sato left the squad due to "circumstances at his club." This phrase is very vague. In Japanese football media, such vague language is used when the real reason cannot or is not disclosed. The reason behind Sato's departure is unclear. Whether there was some issue between the club and the national team, or whether Sato had some personal problem — this is uncertain.
The deeper problem in Japanese football
This incident reveals a deeper problem in Japanese football. The Japanese national team is one of the strongest teams in the world. But the depth of the defense is limited. When the main defenders get injured, Japan has to rely on domestic league players. This is a structural weakness of Japanese football.
The Japan Football Association (JFA) needs to solve this problem. The depth of the defense needs to be increased. New defenders need to be developed. And measures need to be taken to prevent player injuries.
Temporary solution
The call-up of Araki and Mochizuki is a temporary solution. Both are among the best players in Japanese football. But fielding them together means building a new defense. It will take time to build cohesion in this defense. How successful this defense will be in the match against Ecuador on October 1 will be seen.
The path forward
This incident is a learning experience for Japanese football. The depth of the defense needs to be increased. New defenders need to be developed. And measures need to be taken to prevent player injuries.
This is a big opportunity for Araki and Mochizuki. If they play well, the chances of them securing a regular place in the national team in the future will increase. But at the same time, they will need to handle the pressure.
Conclusion
This crisis in Japan's defense is temporary. But within it lies a deeper problem in Japanese football. The depth of the defense needs to be increased. New defenders need to be developed. And measures need to be taken to prevent player injuries.
This is a big opportunity for Araki and Mochizuki. If they play well, the chances of them securing a regular place in the national team in the future will increase. But at the same time, they will need to handle the pressure.
This incident is a learning experience for Japanese football. The depth of the defense needs to be increased. New defenders need to be developed. And measures need to be taken to prevent player injuries.
