The Reality of 'Indoor Consumption' in the Summer of 2026: Driven by Record-Breaking Heat and All-Time High Bonuses

It is too hot to go outside. If that is the case, let's have fun in a cool indoor space. This natural shift in behavior has become an unexpected investment theme in the stock market in the summer of 2026. It was previously thought that extreme heat was bad for consumption, but now, attention is shifting toward 'companies that profit because it is hot.' Let's look at why this is happening, step by step.

From 'Heat is a Loss' to 'Companies that Profit from the Heat'

With record-breaking heat day after day, the way we spend our time has definitely changed. More people are refraining from going out during the day and are thinking about how to spend their time in cool places. This change in behavior has begun to be reflected directly in corporate sales and stock prices.

Until now, extreme heat was seen as a negative factor that reduced outings and cooled consumption. However, the situation is different in the summer of 2026. Investor money is beginning to flow into 'indoor consumption' for spending time in cool rooms and the service industries that support it. The background to this is the fact that household budgets are actually becoming more comfortable. I will delve into this specifically from here.

Investment money tired of semiconductors has turned to familiar service industries

In the stock market, the flow of money is changing significantly right now. AI and semiconductor-related stocks have long led the market, but the reaction to their continued rise has made price movements volatile, and a feeling of 'wanting to take a break' has spread among investors. As a result, funds are moving toward familiar service industries where performance is easier to read and feel secure about.

The symbol of this is the 'Service Industry' sector index, one of the sector indices of the Tokyo Stock Price Index (TOPIX). On July 14, 2026, this index hit its highest level in about 26 years, since February 2000. It has returned to a point where the peak reached during the IT bubble era is now in sight.

On the same day, Round One, which operates complex leisure facilities, and travel service stocks rose, and 're-evaluation buying' spread, centered on leisure-related stocks.

Why did this trend occur? The reasons can be summarized into the following three points:

・AI and semiconductor stocks have seen volatile price movements due to the reaction of rising too much, and buying and selling are mixed.

・Money looking for a place to go is becoming more likely to head toward stocks that had been lagging behind until now.

・Supported by domestic consumption, service industries with easy-to-forecast performance are being chosen as 'targets that can be bought with peace of mind.'

As insurance against the volatility of global high-tech stocks, money is heading toward service industries supported by domestic demand, especially leisure-related ones. The market perceives this as a well-thought-out choice.

Record-high bonuses have made consumers bullish

Why is consumption not falling even though prices are rising? The answer is that the money households can actually spend is increasing.

In the 2026 summer bonus survey (final tally) compiled by Nikkei Inc., the average payment amount across all industries was 1,044,168 yen, up 4.49% from the previous year. It has hit a record high for the fifth consecutive year and has exceeded the 1 million yen mark for the first time since the survey began.

There is also a tailwind in terms of wages. 'Real wages,' which account for the impact of prices, rose 1.4% year-on-year in May 2026 according to the Ministry of Health, Labour and Welfare's Monthly Labour Survey, marking the fifth consecutive month of increase. This means that even if prices rise, wages are increasing at a faster pace.

Companies are also finding it easier to raise prices, and a positive trend is emerging where people are 'enjoying slightly better services with increased wages' rather than 'refraining from buying because of high prices.' If it is for coolness and comfort, they will pay a reasonable amount of money. Consumers today are showing such a bullish stance.

Two companies earning indoors: Round One and Aeon Fantasy

The harsher the outside, the higher the value of indoor leisure where you can play in the cool. Industry leaders are firmly translating this tailwind into performance.

First, there is Round One. In addition to bowling and karaoke, crane games are performing well, with domestic existing-store sales in June 2026 increasing by 14.8% compared to the same month last year, marking the ninth consecutive month of year-on-year growth. According to the company, when accounting for calendar shifts, the actual increase was approximately 17%.

The company also has a pillar of growth overseas, with its U.S. subsidiary, Round One Entertainment, announcing on May 6, 2026 (U.S. Eastern Time) that it had confidentially submitted a draft registration statement for an initial public offering (IPO) to the U.S. Securities and Exchange Commission (SEC).

While this is seen as a potential new catalyst for the stock price if realized, it is important to note that the timing and pricing are undecided, and a listing is not guaranteed.

Another company is Aeon Fantasy. By leveraging its locations within shopping centers, it is increasing its presence as a place where families can stop by to cool off during extreme heat.

Driven by limited-edition products catering to 'oshi-katsu' (fan activities) and improvements to existing stores, sales for the first quarter of the fiscal year ending February 2027 reached 24.575 billion yen, a 12.2% increase year-on-year. The full-year net profit forecast is 3 billion yen, a 7.5% increase from the previous fiscal year, anticipating a recovery from the previous year's deficit.

Why 'AOKI of Suits' started making money from entertainment

A symbol of this summer's changes is AOKI Holdings. While you might have a strong image of 'AOKI the suit retailer,' what is currently supporting the company are indoor leisure businesses such as the internet cafe 'Kaikatsu CLUB,' the karaoke chain 'Cote D'Azur,' and indoor golf. Anticipating an era where suits would become harder to sell, they have expanded their business into lifestyle-oriented entertainment fields.

However, it is not the case that 'non-fashion businesses now account for more than half.' Looking at the sales ratio by segment for the fiscal year ended March 2026, fashion still accounts for the majority at 51.6%, while entertainment is at 38.6%.

Even so, the entertainment business has seen five consecutive terms of revenue growth due to the expansion of private-room stores and an increase in average customer spending, with segment profits reaching an all-time high. The fact that they have cultivated revenue sources that are less susceptible to weather and economic conditions is what is leading to their current valuation.

The 'Kingdom of Dreams' also fights the heat: Oriental Land's price hikes

Oriental Land, which operates Tokyo Disney Resort, a representative of outdoor leisure, is also trying to overcome the adverse conditions of extreme heat through brand power and technology.

The company will raise the maximum price of its 1-Day Passport starting in October 2026. According to reports, the maximum price for adults will increase by 1,500 yen to 12,400 yen, and for children aged 4 to 12, it will increase by 300 yen to 5,900 yen; this increase applies only to certain high-demand days. The background to the price hike includes rising labor and management costs.

To ensure visitors remain satisfied despite the price hikes, the company is focusing on services such as its official app, which shows wait times and current locations. By using digital innovations to reduce stress caused by the unavoidable heat, they aim to balance high prices with customer satisfaction.

How will our spending habits change this summer?

The surge in indoor consumption in the summer of 2026 does not appear to be a passing trend. It can be seen as an established lifestyle born from the combination of unavoidable extreme heat and economic changes, such as rising wages and the permeation of price increases.

As we change how we spend our time to cope with the heat, we are increasingly choosing to pay for 'comfortable experiences' rather than just low prices. The influx of investment money into the service industry can be said to reflect the fact that the standard of value in the Japanese economy is shifting from 'cheapness' to 'quality of experience.'
