Founder & Editor-in-Chief
Taro spent a decade in the music industry as a tour manager, crisscrossing the globe with artists and crews who demanded gear that actually worked. From overnight buses in the American Midwest to bullet trains in Japan, backstage in London to festival grounds across Europe—he's lived out of bags, cases, and carry-ons for years. That experience taught him what separates travel gear that survives the road from stuff that falls apart after one trip. Now he channels that hard-won knowledge into TravelGiftList, helping travelers find products that meet real-world demands.
