NOSIGNER Launches Multilingual Audio Guide and Tourism DX Platform 'WOUDIO'. Rollout Begins at Yokohama Marine Tower on June 2

NOSIGNER Corporation (Headquarters: Naka-ku, Yokohama; CEO: Eisuke Tachikawa) announces the launch of 'WOUDIO', a multilingual audio guide and tourism DX platform developed in-house. It will debut as the official audio guide 'Yokohama 360°' at the Yokohama Marine Tower (Located at 14-1 Yamashitacho, Naka-ku, Yokohama, Kanagawa; General Manager: Naoki Saito), with services starting on Tuesday, June 2, 2026, coinciding with the Yokohama Port Opening Anniversary. WOUDIO is NOSIGNER's first internal startup, with CEO Eisuke Tachikawa acting as a solopreneur to handle everything from design to development and launch. Yokohama Marine Tower serves as the first facility for full-scale implementation. NOSIGNER contributes to realizing a sustainable society by using the power of design to transform the tourism industry to protect and nurture natural and historical cultural assets.

WOUDIO is a multilingual audio guide and tourism DX platform from the 'evolution-driven design firm' NOSIGNER. It delivers stories related to the history, culture, and landscapes of facilities and regions in multiple languages directly through visitors' own smartphones. The name is a portmanteau of 'World' and 'Audio', embodying the intent to deliver voices to the world. It can be used simply by scanning a QR code with a smartphone, requiring no app download. Supporting up to 18 languages, it goes beyond traditional audio guides to serve as a next-generation platform connecting tourism experiences, disaster prevention information, and donations for cultural preservation.

'Yokohama 360°' is the first full-scale implementation of the WOUDIO platform, serving as the official audio guide for the Yokohama Marine Tower. It provides a new tourism experience that overlays the Yokohama cityscape seen from the observation floor with the history and information tied to those locations. Starting from 20 'questions' set on the observation floor, such as 'What ship couldn't pass under that bridge?' for the Bay Bridge or 'What sleeps beneath the lawn?' for Yamashita Park, visitors just scan a nearby QR code to access deep, unpublished information about Yokohama via AI audio guides in 8 languages. It offers multilingual audio content covering various spots visible from the observatory, including the Hikawa Maru, Osanbashi Pier, Red Brick Warehouse, Chinatown, Motomachi, Yamate, and Sankeien Garden.

Traditional audio guides have mainly been introduced in indoor exhibition facilities like art museums. 'Yokohama 360°' expands this framework, designing the observatory—a place overlooking the entire city—as a single guided space. The audio content encourages visitors to actually walk to spots like Yamashita Park, Chinatown, and Yamate, increasing circulation in the surrounding areas. By physically visiting the sites, the view from the observatory connects with the city's history, proposing a new form of tourism where the observatory is the 'first step of a city walk.'

'WOUDIO' was born from Eisuke Tachikawa's long-held vision to 'protect cultural properties and natural assets through the power of the tourism industry.' Combining the latest generative AI technology with design, it was developed end-to-end by Tachikawa himself. Yokohama Marine Tower was chosen as the first global rollout location because Yokohama is the birthplace of many 'Japan-firsts' (like railways and gas lamps) and is the developer's hometown. Starting here, NOSIGNER aims to expand the system to domestic and international facilities, broadcasting local history and cultural value in multiple languages. Furthermore, the platform features disaster prevention capabilities, switching to multilingual navigation to the nearest evacuation shelter during an emergency. WOUDIO operates with a mission to transition the tourism industry from an 'industry that consumes places' to an 'industry that nurtures places.'
