About Tokyu Toyoko Line, Den-en-toshi Line, and Tokyu Bus in-train advertisements

Hello, this is Jefferson's Balloon. This time, we will introduce in-train advertisements on the Tokyu Toyoko Line, Den-en-toshi Line, and Tokyu Bus!

Jefferson's Balloon started placing in-train advertisements on the Tokyu Toyoko Line and Den-en-toshi Line from October 1, 2024, hoping that as many people as possible would get to know our balloons!

Then, in July 2025, with the launch of our delivery service through Uber Eats, we also began placing in-bus advertisements on Tokyu Bus.

Furthermore, in November 2025, we updated the visuals for our train advertisements. We aimed for a vibrant creative that conveys the excitement of receiving a balloon as a gift.

Jefferson's Balloon will continue to strive to be a beloved service that stays close to the community. Please look for Jefferson's Balloon advertisements inside the vehicles!
