In 1612, Yasui Doton invested his fortune to carve a canal through Osaka's heart—but his death in the Siege of Osaka left whispers of a darker truth
You are Doton Yaemon, the visionary merchant of Osaka in 1612.
You must follow the tracks of your rivals to foil a plot threatening Osaka's commercial balance. Your
Dive into Osaka's secret alleys, where Edo-era merchants wove the threads of legendary prosperity, and unravel the mysteries of a forgotten conspiracy.
Your quest begins near Ebisu-bashi Bridge, an iconic Dotonbori landmark built in 1910, connecting Chuo-ku and Naniwa-ku in Osaka. This approximately 100-meter long bridge, famous for its views of Dotonbori Canal and illuminated neon signs, is named after Ebisu, the god of commerce and fishing. It is here, at this gathering spot for festivals like Tenjin Matsuri for decades, that your first clues are hidden, blending the district's mercantile history with a contemporary enigma. The influence of Osaka's merchants is palpable, even a century after its construction.
Continue towards Hozenji Temple, a Buddhist temple founded in 1637 in a narrow Dotonbori alley. This 10-square-meter space, known for its traditional stone lanterns and mystical ambiance, houses the moss-covered Fudo Myoo statue, a result of visitors pouring water on it since the 17th century. This place of prayer for commercial prosperity, linked to Edo-era merchants, holds crucial information. The Kuromon Ichiba Market, established in 1822 as 'Musubi-no-ichi', stretches for 580 meters in Naniwa-ku, Osaka, with over 150 shops selling fresh seafood and Kobe beef since the Edo period. This market, a nerve center of food trade, survived the 1945 Osaka bombing and was rebuilt in the 1950s, a testament to the resilience of Japan's cultural heritage.
Your itinerary leads you to the National Bunraku Theatre, inaugurated in 1984 in Nipponbashi. Dedicated to bunraku, the traditional Japanese puppet theater classified as a UNESCO Intangible Cultural Heritage in 2008, it is the heir to the Takemoto-za theater founded in 1684 by Takeda Izumo I. With its 700-seat capacity and 12-meter deep mechanical stage, this venue is intrinsically linked to Osaka's mercantile culture. Shinsaibashi-suji Shopping Street, a 600-meter covered arcade opened in 1933, connects Shinsaibashi to Namba in Chuo-ku. Japan's oldest arcade with a fire-resistant glass roof, this historic shopping center since the Meiji era (1868-1912) has seen merchants and ruined samurai pass through, its 300 traditional lanterns lighting your way to the truth.
Namba Yasaka Shrine, a Shinto shrine founded in 1700, is your next stop, recognizable by its 15-meter wide 'lion's head' stage. Dedicated to six kami protecting against epidemics and for merchant prosperity, this 3300 m² complex houses 12,000 stone lanterns offered by local traders since the Edo era. It is a site of annual rituals like Setsubun for over 300 years, where the secrets of ancient merchants are still honored. Sennichimae Doguyasuji Shopping Street, a 180-meter shopping street dedicated to kitchen utensils since 1910, is nicknamed 'Kitchen Town'. With over 70 shops selling knives and tableware, it is a legacy of Taisho era blacksmith merchants, a supply center for the district's restaurants for a century.
Your journey concludes along the Dotonbori Canal, the historic heart of Osaka's pleasure district, dug in 1612 by the merchant Doton Yaemon. This 1.7 km artificial canal, launched as a commercial project to attract theaters and kabuki, generated mercantile prosperity from the 1620s. Iconic bridges like Ebisu-bashi were added in the 19th century for increasing pedestrian traffic. By exploring these sites, you not only piece together the conspiracy but also the history of Osaka with your family, an interactive visit to the Kansai heritage, where every monument and edifice tells a part of the commercial and cultural richness of this emblematic city. This outdoor escape game in Osaka is a thematic circuit to discover the history of Osaka, a true GPS treasure hunt in augmented reality for a unique exploration.
