Newtec Japan Launches 'HEAT BLOCK INNER' on Makuake: A Heat-Shielding Inner Tarp to Upgrade Existing Canopies
Newtec Japan Co., Ltd. will begin pre-sales of the 'HEAT BLOCK INNER', a heat-shielding inner attachment for existing one-touch tarps, on Makuake from May 18, 2026. It suppresses temperature rises by up to 12°C through thermal insulation created by an air layer, and features a universal design compatible with tarps from other manufacturers.

Newtec Japan Co., Ltd. (Headquarters: Yokohama, Kanagawa; Representative Director: Norihiro Shiraishi) announces the pre-sale of 'HEAT BLOCK INNER' on the support purchase service 'Makuake'. This new product from the one-touch tarp brand 'KANTAN TARP', which boasts a cumulative domestic sales volume of 3 million units, enhances thermal insulation effects utilizing the latest heat-shielding fabric and an air layer.
Due to the severe heat in recent years, the problem of being 'hot even in the shade' has become significant in outdoor scenes such as club activities, events, leisure, and work sites requiring extreme heat countermeasures.
While general one-touch tarps can block direct sunlight, the roof portion retains heat, and because of the high water resistance of the fabric, hot air can get trapped inside.
This is why the 'HEAT BLOCK INNER' was developed.
This product forms an 'air layer' by adding a heat-shielding inner canopy inside the tarp roof.
By utilizing the thermal insulation property of air, the intermediate air layer reduces the heat from outside the canopy, suppressing the temperature rise inside the tarp where people are active.
In tests, a maximum difference of approximately 12°C* was confirmed under the tarp.
It supports the creation of a more comfortable space even outdoors in midsummer.
Furthermore, one of the major appeals of this product is that it adopts a universal design compatible not only with Kantan Tarps but also with other manufacturers and various sizes. (Available in two sizes: compatible with 240-250-260cm / compatible with 300cm)
We propose a new option: not 'replacing your tarp', but 'updating your existing tarp'.
In addition, it can be easily installed without tools, making it easy to handle for beginners and women.
In recent years, along with changes in the outdoor environment due to extreme heat, the value of 'using existing things for a long time' from a sustainable perspective is spreading.
The 'HEAT BLOCK INNER' will be deployed as a new one-touch tarp accessory that balances comfort and sustainability.
In recent summers, it is no longer safe to say 'you are fine once in the shade'.
After 15 years of prototyping, we have completed 'the highest standard of heat-shielding structure for tents and tarps, using fabric with the highest heat-shielding rate (over S65+) and insulating with a middle air layer'. The secret to this highest standard is the same principle as double glazing used in houses.
And as proof of originality, it is a developed product with registered patents and designs. (Patent No. 6059869, Design No. 1465023)
We developed this product with the desire for people to use their existing tarps more comfortably and for a longer time. We hope that everyone who owns a one-touch tarp will experience the difference.
■ Product Overview
Product Name: HEAT BLOCK INNER
Application: Heat-shielding inner canopy for one-touch tarps
Features:
- [Extreme heat countermeasure] With a multi-layered roof of black PU coating, the air layer that makes it hard for heat to pass through reduces the temperature by up to* -12°C.
- [Universal design] Can be retrofitted to the one-touch tarp you currently own, regardless of the manufacturer.
- [Reduce] Can be easily set up by anyone in a few minutes without tools, evolving old tents to the highest standard of heat-shielding specifications.
Size: 240-250-260cm compatible size / 300cm compatible size (both for square one-touch tarps)

Project Publication Date: Monday, May 18, 2026

Implementation Platform: Makuake
■ Notes
*Test method: Applied JIS L 1951 (Heat shielding property test). Conducted in a product state (3-layer lamination).
*Test results: In an irradiation test with a reflector lamp (30 minutes), it was confirmed that the temperature of the heat-ray receptor was suppressed by up to 23.8°C compared to an unprocessed product (blank) (blank 56.1°C, provided sample 32.3°C).
*The above figures are measured values under the test environment, and the effects will vary depending on the actual usage environment (temperature, humidity, sunshine conditions, presence of wind, etc.).
*These results are for the test sample and do not guarantee the quality of all product lots.
