65.3°C without a parasol: Why the 'Hareshizuku' umbrella, which sold 28,000 units in one season with a 34.9°C heat-shielding effect, is the top choice | Rakuten & Amazon Sale

The 'Hareshizuku' folding umbrella, developed by the brand 'BELLEMOND' under Fun Standard Inc., has gained popularity as an 'all-in-one umbrella,' selling 28,000 units in a single season. It has garnered attention for its high heat-shielding effect, recording a 34.9°C difference in third-party tests. Amidst recent extreme heat, more people are choosing umbrellas based on 'heat-shielding' rather than just 'light-shielding.' In heat-shielding tests conducted by a third-party organization, after 30 minutes of artificial solar irradiation, the mannequin head temperature was 65.3°C without the umbrella, compared to 30.4°C with it, confirming a 34.9°C difference. Developed with the concept of an 'umbrella for all seasons, including rainy and winter days,' the 'Hareshizuku' features 100% light-shielding, 100% UV protection, an ultra-lightweight design starting at 126g, and is both rain-and-sun compatible with an absorbent cover. Currently, Rakuten is offering a 1,010 JPY off coupon for the Hareshizuku series from May 31, 2026, to June 9, 2026. Amazon is holding a Smile Sale until June 2, 2026.
