• Background

    For the New Travel Ecosystem

    Owning to the deregulation and the rise of Asian economies, Japan's inbound tourism market is growing rapidly.

    The number of foreign visitors to Japan has increased from 10.4 million in 2013 to 28.7 million in 2017. The Japanese government aims to increase the number to 40 million in the year of Tokyo Olympics, 2020. However, there are several problems that needs to be solved.

    The first is infrastructure-level preparation for foreign tourist. For instance, hotel and transportation in Japan does not have enough multilingual staff, wifi, and multilingual guides, and these lead to dissatisfaction of the foreign tourist.

    Also, the country does not have enough local travel programs that foreign tourists can enjoy. It is necessary to increase the number of high-quality sports, entertainment, and cultural programs for them to improve their overall experience.

    Finally, travel data has been siloed. It is owned by each service provider and has not been integrated or efficiently utilized.

    We have decided to host this hackathon to solve these problems and improve traveller’s experience with the power of Ethereum.

    This hackathon will be hosted by blockchain experts and top Japanese companies in various fields. We aim to ideate a new type of seamless travel experience for each foreign tourist and launch a new blockchain-based service by 2020.
