Y!mobile (stylized as Y!mobile, pronounced “ワイモバイル” / wai-mobairu) is a Japanese mobile telecommunications brand operated by SoftBank Corp. The brand was created in 2014 through a partnership between Yahoo! JAPAN and the newly merged company formed from eAccess (formerly e-mobile) and Willcom. The current logo was introduced on August 1, 2014, replacing the separate “イー・モバイル” (e-mobile) and “ウィルコム” (Willcom) brand logos, which were retired on that date.[1]
Design and History
The Y!mobile logo was unveiled on July 17, 2014, at a press conference announcing the new brand and its services. The official press release from Ymobile Corporation and Willcom Okinawa confirmed that the e-mobile and Willcom brands and logos would be unified under the Y!mobile mark effective August 1, 2014.[1] The logo was displayed prominently at the launch event, where attendees noted it bore a visual resemblance to the Yahoo! logo at first glance.[2]
The brand name itself was a deliberate choice. At the launch event, Ymobile CEO Eric Gan explained that the “Y” in Y!mobile carried multiple meanings: it referenced Yahoo! JAPAN, but also stood for words like “Enjoy” and “Happy,” with the intent of casting a “Y-spell” on users.[3][4] The exclamation mark was retained from the Yahoo! naming convention, reflecting the close partnership between the two companies.[5]
The logo was first shown publicly in March 2014, when Yahoo! announced its plan to acquire eAccess and launch the “Y!mobile” brand as Japan’s first “internet carrier.”[6] The brand officially launched on August 1, 2014, with the opening of 1,023 Y!mobile shops nationwide.[5]
Meaning and Symbolism
The Y!mobile logo is rendered in a bold red, a color that was visibly associated with the brand from its launch. At the July 2014 press event, CEO Eric Gan appeared on stage wearing a bright red T-shirt printed with the Y!mobile logo, deliberately signaling a departure from the previous corporate image.[3] The red and white color scheme of the logo has been consistently described in coverage of the brand’s storefront signage.[7]
The “Y” character itself carries the documented brand meaning: beyond the Yahoo! connection, it was explicitly positioned by the company’s CEO as representing positive concepts such as “Enjoy” and “Happy,” with the brand aiming to bring the power of “Y” to users.[4]
Typography and Design
The Y!mobile logo uses a horizontal lockup format, with the wordmark “Y!mobile” set in a clean, rounded sans-serif typeface. The logo is available as an SVG file hosted on the official Ymobile website, confirming its continued use as the brand’s primary digital asset.[8] The design was noted at the launch event for its visual similarity to the Yahoo! logo, reflecting the close brand association between the two companies at the time of the rebranding.[2]
