【Reiwa no Tora】Two New Tigers Clash! Ultra-Cooling Vest Sales Battle Begins

The 'Ultra-Cooling Vest Sales Battle' has begun, featuring Tsuda Atsushi, Representative Director of AT Corporation, and Yamamoto Masatoshi, Representative Director of Yamamoto-kun Corporation, both appearing as 'Tigers' on the popular YouTube program 'Reiwa no Tora'.

This is a program-originated, practical business battle in which the two 'Tigers' who invested in our office—the 64th applicant in the Business Revival Edition—now take on the challenge of selling the product themselves.

The 'Ultra-Cooling Vest' that cools your body effectively with just water

Investment is not the end—our support continues through to 'sales' after product completion

Our office appeared as the 64th applicant in the 'Business Revival Edition of Reiwa no Tora,' presenting a business plan to maintain delivery contracts with existing customers even after becoming independent from our former Chinese partner company.

The challengers were invested in by Presidents Tsuda and Yamamoto, who appear on 'Reiwa no Tora'.

As follow-up initiatives progressed, they expressed the desire that 'delivering only to contracted companies is a waste' and 'we should spread this product more widely this summer.' As a result, the two investors each took responsibility for selling 1,000 units, sparking a sales battle where the first to sell out would be declared the winner.

Both CEOs have built successful track records in different industries. This project draws attention not only to sales numbers but also to their respective sales strategies, outreach methods, and business acumen.

The rule: '1,000 units each—the first to sell out wins'

The sales battle rules are simple.

Presidents Tsuda and Yamamoto each take charge of 1,000 units of the Ultra-Cooling Vest. The first CEO to completely sell their 1,000 units wins.

How to Use

The Ultra-Cooling Vest now on sale was developed for heat protection in a wide range of scenarios, including outdoor work during hot seasons, sports events, outdoor activities, festivals, and commuting or school travel. Using evaporative cooling technology, it provides a cooling sensation for up to 2–4 hours simply by wetting and wringing it out.

Wearing it alone is sufficiently cool, but when worn under fan-equipped apparel, it prevents hot air from merely circulating—even in environments exceeding 35°C, the cooling effect from the fan persists.

Unlike types that use electric fans or ice, this vest requires no battery, is lightweight, reusable, provides long-lasting cooling, and has high water retention, ensuring the clothing underneath stays dry.

※This product is not a medical device. The perceived cooling effect and duration may vary depending on the environment, temperature, humidity, airflow, and wearing conditions.

※The cooling technology related to this product has been patented by our company as a booster for fan-equipped apparel.

A product saved by a YouTube program enters the market with viewer support

From appearing on the 'Business Revival Edition of Reiwa no Tora,' to investment, delivery, and now general sales.

This sales battle is also an initiative to share with viewers how proposals and support exchanged on the program translate into real business outcomes.

How will the completed product be received in the market? And which of the two CEOs—President Tsuda or President Yamamoto—will sell 1,000 units first? Viewer feedback will be directly reflected in future product development starting next year.

A new business revival story begins, extending the program's narrative into the real market.
