    For the central metropolitan area, the Tokyo Metropolitan Police Department(TMPD) handles accidents, incidents, and other various phenomena as well as a vast array of administrative operations, including the processing of notifications associated with driver's licenses and other matters, by giving multiple police stations jurisdiction over individual areas. On the other hand, in the case of the Tokyo Islands, the TMPD does the same with five police stations on Oshima, Niijima, Miyakejima, Hachijojima, and Ogasawara that have jurisdiction over nine towns and villages. The Tokyo Islands have relatively few traffic accidents, in part because they have little traffic volume. A characteristic of the traffic accidents that occur there is that they are caused by tourists driving rental cars in many cases.

    On one hand, our remote islands are tasked with key roles such as safeguarding of national boundaries and Exclusive Economic Zones, use of maritime resources, inter-generational preservation of diverse cultures, and environmental conservation; on the other hand, they face difficult natural and social conditions compared to other regions, being surrounded on all sides by water, enduring ongoing long-term depopulation, and experiencing relatively high shipping cost for everyday necessities and other items, among other challenges. Due to the secircumstances, the government has been implementing a number of policies necessary for revitalization of remote islands as well as enacting laws such as the Remote Islands Development Act. The Agency for Natural Resources and Energy has initiatives that seek to ensure that remote islands are supplied bothreliably and at low cost with petroleum products that are everyday essentials, including fuel for automobiles, an important form of transportation on remote islands.

    There are many remote islands in Japan. Most of these islands are connected by bridges, but still some islands have only ferry boats or passenger ships between the island and the mainland as vital means for transportation. The residents of the remote islands have to transfer from a ferry boat to a local bus at a transport hub when they visit the main island to go shopping or hospital and so on. For the elderly residents, it is a burden to wait for a long time for the bus or the ferry boat and to change transportation vehicles at the transport hub. The author s have evaluated the burden by the generalized time. The generalized time is a measure which evaluates the mobility burden for users of remote islands route, and obtained easily and quantitatively by investigating walking speed and transit behavior. However, we were not able to confirm whether the acquired results are specific to the solitary island surveyed or it can be expanded to general remote islands. In this study, we investigated another remote island area and clarified differences of the equivalent time parameter and the psychological lost time depending on residential areas.

    Seaplane transportation is appropriate and useful for Japan, where is an island state, especially remote island areas. We have proposed utilization of seaplanes for regional recreation science the Great East Japan Earthquake. The seaplane transportation business has been restarted in Onomichi after half a century in Japan. And attraction activities for seaplane business have been spread to all of Japan by slow degrees. In this paper, Seaplane Network Plan, which has been proposed by authors, is introduced and usefulness, history, leading cases of foreign countries, movements of Japan, and introducing problems are discussed.

    In Okinawa prefecture, bus services play a major role in public transportation, since there is no railway services except for urban monorail. However, management of the bus transportation service is not easy since many private cars are used for transportation. Automated driving of the buses could reduce cost of the operation and rise the quality of the bus services with improved safety and high-frequency operation. With this background, pilot tests of the automated driving bus were carried out in the main land of Okinawa and Ishigaki island in 2017. The article introduces two pilot tests done in the main land, at Nanjo-shi and in the area extending from Ginowan-shi to Kitanakagusuku-son, and one test done in Ishigaki island.
