Japan Daily Sun (JDS) October 13, 2026 – Dozens of participants competed to fall asleep quickly and soundly during a Tokyo event designed to raise awareness of sleep deprivation in Japan. The competition, named “Matt Race”, was organised by a mattress company and offered a prize exceeding ¥2 million, or approximately US$14,000. Contestants rested on mattresses for up to 90 minutes while wearing sleep-tracking devices. The event was organised against a background of concerns about Japan’s comparatively low average sleep duration, with long working hours, commuting and nightlife identified as contributing factors. The winner, known as Suimii, said she intended to spend the prize money on moving into her own home and purchasing a bed.

What happened at Japan’s Matt Race sleeping competition?

Tokyo hosted the unusual sleeping contest on 5 October 2026, bringing together dozens of participants who competed to demonstrate how quickly and soundly they could fall asleep. The event, called Matt Race, was organised by Koala Sleep Japan, a mattress company seeking to draw attention to the importance of rest.

According to Agence France-Presse (AFP), whose report was published by several international news organisations, the contestants were given comfortable mattresses and fitted with sleep-tracking equipment. They were allowed to sleep for up to 90 minutes while their rest was monitored.

The event offered a different approach to a subject commonly associated with healthcare, personal routines and workplace wellbeing. Rather than competing in a physical activity requiring speed or endurance, participants were judged on their ability to fall asleep and achieve sound rest.

The prize exceeded ¥2 million, equivalent to approximately US$14,000, providing a substantial financial incentive for those taking part.

In its report published on 13 October, The Japan Times, carrying the story under the AFP-JIJI byline, described the competitors as self-described elite “competitive sleepers”. The report highlighted the contrast between the contest’s relaxed format and the demanding routines often associated with Japanese working life.

The competition also provided a public platform for discussing sleep in a country where insufficient rest has been a longstanding concern. Its organisers sought to use the novelty of the event to attract attention to a subject that can otherwise receive less public engagement than more visible aspects of health and lifestyle.

Why did the organisers launch a sleeping competition?

The organisers presented Matt Race as an opportunity to increase public interest in sleep by making rest the focus of a shared event.

Riichiro Nakama, the creative director who supervised the planning of the competition, explained the thinking behind the initiative. As reported by AFP, Nakama said: “Japan is often described as a country suffering from sleep deprivation, and people here are very diligent.”

His remarks connected the event with concerns about the relationship between diligence, busy schedules and opportunities for adequate rest.

Nakama also explained that organising a public competition could encourage people to sleep together and become more interested in sleep. The intention was therefore not limited to identifying the participant who could fall asleep most effectively. The event was also designed to make sleep a subject of wider public attention.

The format helped bring that message into a setting that was accessible and engaging. Participants lay down on mattresses rather than undertaking demanding physical tasks, while the monitoring equipment allowed the organisers to assess their sleep.

According to AFP’s coverage, the room was dimly lit, and some contestants held stuffed toys while resting. The surroundings were arranged to accommodate sleep rather than the atmosphere associated with conventional sporting competitions.

Although the event had a competitive structure, the organiser’s stated objective was to raise awareness. The available reporting does not establish whether the contest produced measurable improvements in participants’ sleep habits or changed public attitudes more broadly.

How were the contestants monitored and judged?

Participants wore sleep-tracking devices while resting on mattresses, with monitors attached to their heads. They were given a maximum of 90 minutes to sleep.

The winner was selected according to how quickly and soundly each contestant slept. The combination of sleep onset and the quality of rest formed the basis of the competition.

This meant that the event was not simply a test of who could remain in bed for the longest period. Instead, the organisers sought to distinguish contestants according to how effectively they entered sleep and how soundly they rested during the allotted time.

The use of monitoring equipment was central to the format. Rather than relying solely on participants’ accounts of their experience, the event incorporated devices intended to track sleep.

However, the published reports do not provide a detailed explanation of the scoring system, the precise measurements used to determine sleep quality, or the relative weighting given to falling asleep quickly and sleeping soundly.

It would therefore be inaccurate to assume that the competition used a particular clinical sleep assessment or that its winner necessarily had the healthiest long-term sleep habits.

The available information establishes the basic judging criteria but does not provide enough detail to draw wider conclusions about the medical significance of the results. Matt Race was reported as a public competition organised by a mattress company, rather than a clinical study into sleep disorders.

What did the winner say about the prize money?

The winner, identified only by the nickname Suimii, said the money would help her move towards independent living and purchase a bed she had wanted.

“I want to live on my own, so I think I’ll use the money for the moving costs,” she said, according to AFP.

She also explained that she wanted a bed resembling one fit for a princess and intended to use part of the prize money to buy it.

Her comments offered a personal account of what winning the contest meant to her. Beyond the novelty of being recognised for sleeping well, the prize could help her meet practical housing expenses and purchase furniture for her future home.

Suimii’s decision to use the money for moving costs also demonstrated that the reward had a purpose beyond the competition itself. The contest gave the winner an opportunity to put the financial prize towards a personal goal.

The reports do not provide further details about her living arrangements, the cost of the planned move or the type of bed she intended to purchase.

Her stated plans were among the most distinctive details of the event, illustrating how an unusual competition could carry a direct financial benefit for its winner.

How did participants describe the experience?

Chisato Honda, a 32-year-old participant, described the competition positively and said the sleeping session had passed quickly.

“It was over in an instant. I almost wish I could have slept a little longer,” Honda said, according to AFP.

He also described it as “a happy competition”.

His comments reflected the experience of a contestant who found the event enjoyable and felt that the allotted resting period had passed quickly. His remark about wanting to sleep longer also fitted the central purpose of the competition: participants had gathered specifically to rest rather than to perform a conventional competitive task.

The event’s format gave contestants a temporary opportunity to lie down in a prepared environment without the usual demands of work or daily activities.

Nevertheless, one participant’s positive reaction should not be treated as evidence that everyone experienced the event in the same way. The published reports do not include a comprehensive survey of participants or detailed feedback from every contestant.

What the available accounts establish is that Honda regarded the competition as enjoyable and that the winner intended to put the prize money towards personal plans.

Together, the comments from Honda and Suimii provided a human perspective on an event otherwise centred on sleep tracking, competition rules and broader concerns about rest in Japan.

Why is sleep deprivation a concern in Japan?

The contest took place against a background of data indicating that Japan had a comparatively low average sleep duration among countries included in an international comparison.

According to figures cited in AFP’s reporting, Organisation for Economic Co-operation and Development (OECD) data published in 2021 showed that people in Japan slept an average of seven hours and 24 minutes per day. The report described this as the lowest average among the OECD countries included in the comparison.

The figure provides an important context for the competition because it links the organisers’ stated objective to an established public discussion about sleep.

Experts cited in the news reports identified several factors that can contribute to limited sleep in Japan, including long working hours, lengthy commutes and a busy nightlife economy.

These factors can affect the amount of time people have available for rest. Work commitments may extend beyond the formal working day, while travelling between home and the workplace can reduce the time left for sleep and other personal activities. Social commitments and nightlife can also compete with time that might otherwise be spent resting.

However, these factors should not be interpreted as affecting every person in Japan equally. Individual working arrangements, commuting requirements and personal routines differ, and the reported national average does not describe every person’s sleep pattern.

The OECD figure is also historical rather than a measurement of sleep duration in October 2026. It offers context for understanding the organisers’ concerns but does not, by itself, establish the current average or demonstrate that sleep duration has improved or deteriorated since 2021.

The distinction matters because a public event can raise awareness of a problem without providing new evidence about its scale.

In the case of Matt Race, the organisers used the reported concern about sleep deprivation as a reason to encourage greater public interest in rest. The available coverage does not establish that the event was part of a government-led health programme or a formal national sleep policy.

What role can mattress companies play in raising sleep awareness?

Matt Race illustrates one way a mattress company can use a public event to connect its products and activities with a wider discussion about rest.

Koala Sleep Japan organised the competition, providing the setting in which participants could rest on mattresses and be assessed using sleep-tracking devices. The event combined product-related surroundings with a broader message about the importance of sleep.

For the company, the format created a public-facing activity that was distinct from conventional mattress advertising. It placed the experience of resting at the centre of an event and invited participants to engage with the subject directly.

The approach also made the competition suitable for news coverage because it combined a recognisable everyday activity with unusual rules and a substantial prize.

However, the available reporting does not quantify the event’s commercial impact, indicate whether mattress sales increased, or establish whether it changed consumers’ purchasing decisions.

Nor does the competition establish that a particular mattress alone can resolve insufficient sleep caused by work, commuting or other demands on people’s time.

The reported circumstances instead underline the distinction between the environment in which a person sleeps and the amount of time available for rest. A comfortable sleeping space may form part of a person’s routine, but the competition’s stated public-awareness objective concerned sleep more broadly.

The event’s significance can therefore be described in terms of how it attracted attention to sleep, rather than as evidence of a proven health or commercial outcome.

Background: What is the wider context behind Matt Race?

Matt Race emerged from concerns about sleep duration and the pressures associated with busy working and commuting routines in Japan.

The OECD’s Health at a Glance 2021 publication provides international health indicators, including data relevant to comparisons between countries. The sleep-duration figure cited in coverage of Matt Race placed Japan at the bottom of the reported comparison, with an average of seven hours and 24 minutes per day.

That figure helped establish the context for the competition, although it does not explain every cause of insufficient sleep or establish the circumstances of each individual.

The October 2026 event was organised by Koala Sleep Japan, with creative director Riichiro Nakama overseeing its planning. Dozens of contestants took part, using sleep-tracking devices while resting for up to 90 minutes.

The judging criteria focused on how quickly and soundly the participants slept. The winner received a prize exceeding ¥2 million, and Suimii said she planned to use the money towards moving costs and a new bed.

The event also attracted attention through its unusual format, in which sleeping became the activity being judged rather than a break between other activities.

Reporting by AFP, reproduced by outlets including The Japan Times, documented the competition and the statements of its organiser, winner and participants. The reports support the conclusion that the event was intended to encourage interest in sleep, but they do not establish its longer-term effects on public health or sleeping habits.
