Challenges for Drivers During Summer Outings and Intense Heat Season

July is the time to plan long-distance trips by private car, with the much-anticipated summer vacation and Obon holiday season just around the corner.

However, at the same time, Japan's summers have been experiencing severe heatwaves in recent years, and "discomfort due to abnormal increases in in-car temperature" and "deterioration and dirt from sunlight and long-distance travel" are major challenges for enjoyable family drives.

According to Japan Meteorological Agency data, intense heat is expected again this year, with temperatures predicted to be average or higher than average. Consequently, the risk of heatstroke, fogging of car windows, and the formation of water spots are expected to increase significantly.

Therefore, we have planned a sale of carefully selected car accessories directly related to "summer car life" on Amazon Prime Day, timed for this pre-outing period, to help all drivers make their in-car environment comfortable and safe.

This is an opportunity to significantly improve the quality of your daily drives while keeping costs down.
