Background: Heatstroke Risks of Outdoor Barbecues

### The Triple Challenges of Summer Barbecues

- Outdoor BBQs pose heatstroke risks, making it difficult to bring children or elderly people. - Indoor alternatives are often avoided due to concerns about smoke and odors. - Indoor facilities are typically crowded, making it hard to find private, bookable spaces.

In April 2026, the Japan Meteorological Agency officially named days with maximum temperatures of 40°C or higher as 'Severe Heat Days' (※1). Amid increasingly intense summer heat, even traditional summer leisure activities like barbecues carry heatstroke risks when held outdoors. At Spacemarket, the number of rental space bookings for BBQ purposes in August increases to approximately 12 times the lowest monthly usage (※2). As summer peaks, demand for BBQs is rising sharply, along with the need for comfortable environments that remain enjoyable even during extreme heat.

To meet growing demand for summer BBQs and address concerns about heatstroke—especially among children—Spacemarket is introducing two initiatives: the 'Cool AC Spaces' campaign and the renovation of 'TheSpace Kinshicho,' offering a new, cool, and comfortable way to enjoy summer.

Customer Booking Comments for BBQ Use

- We used to have BBQs outdoors, but it was too hot, especially with kids. Finding this indoor BBQ facility means we can finally gather together again. - Hosting a moms' gathering with 10 mothers and 11 children (ages 2–4). It's great to have an indoor option since it's so hot outside. - We're having a circle BBQ. The fact that we can do it indoors, away from the heat, is very appealing.

About the Renovation and Reopening of 'TheSpace Kinshicho'

'TheSpace Kinshicho,' a rental space in Tokyo's Kinshicho operated by group company Spacemall, will be renovated and reopened on July 20, 2026, as a more comfortable venue for 'cool BBQ' experiences.

'Cool BBQ' refers to enjoying barbecues in air-conditioned indoor spaces or on shaded, roofed rooftops, allowing for comfortable and refreshing BBQs even on Severe Heat Days. It is suitable for a wide range of occasions, including family-friendly moms' gatherings and company or department parties.

### Key Features After Renovation

- The rooftop (※) is adjacent to the indoor space, allowing quick breaks indoors even on hot days. - A new pergola has been installed on the rooftop, enabling tarps to be set up to block strong summer sunlight for a more comfortable BBQ. - Enjoy open-air rooftop BBQs with a sense of freedom, even in central Tokyo. - A seamless indoor-to-rooftop flow design allows access without removing shoes. - For those who prefer indoor BBQs, the 'XGRILL PREMIUM,' which reduces smoke by approximately 94%, is available—allowing for a comfortable experience without worrying about smoke or odors.

※ The rooftop will be completed in September.
