Foreign residents in Japan are classified as one vulnerable group at risk of disasters. Therefore, various measures are in place to engage, educate and offer first-hand experiences of disaster countermeasures required to overcome systematic disaster preparedness problems. However, the need for Japan to prevent the spread and infection of COVID-19 has necessitated measures that prohibit public gatherings and other social activities. This study aims to look at how these arrangements have impacted public engagement approaches to disaster preparedness for foreign residents within the Tokyo Metropolitan Area.

This study identifies local organizations and examines their methods of engagement that enhance the disaster preparedness of foreign residents in the Tokyo Metropolitan Area. The activities are examined in the context of when there was no COVID-19 pandemic and the current state of the pandemic. A change in activities attributed to the COVID-19 pandemic is then extracted and explained through field surveys and interviews with the relevant organization.

This study reveals that most disaster preparedness activities were best accomplished through in-person engagements. Nevertheless, online engagements have become the alternative option because of COVID-19 infection prevention. This change has widen the coverage of some activities but major setbacks include events cancelations and technical and technological challenges attributed to using online platforms.

This study did not examine the effectiveness of pre-COVID-19 pandemic engagement approaches and current changes attributed to the pandemic; many public engagement literatures acknowledge success to include the number of participants, the abilities of organizations to find ways to effectively and positively engage their stakeholders for meaningful partnerships, the number of clicks, access to a website and comments made online. Therefore, as organizations in this study have shown a glimpse of the above characteristics, there are indications of some level of effectiveness in their engagement approaches even amid a pandemic.

To avoid such situations in the future, there is the need for the Tokyo Metropolitan Government, local governments and associated organizations to develop public engagement approaches that are flexible to resist or cope with in-person, remote encounters, or sudden circumstances that could potentially derail planned activities.

The most effects attributed to the COVID-19 pandemic are the cancelation of many disaster drill exercises, community disaster walks, training of volunteers for foreign residents’ assistance and many hours of “Yasashii Nihongo” lesson. The cancelation of activities is a setback to the efforts of self-help and mutual aid campaigns by authorities to reduce the impacts of disasters.

The spirit of inclusion has been an embodiment of disaster management approaches in Japan for years for which policy recognitions have been tagged along the dimensions of public aid, self-help and mutual aid. These are aimed at engaging the populace, especially foreign residents in disaster training and exercises, language study and other communal activities for disaster preparedness. However, to prevent the spread of COVID-19, there have been a series of restrictions on gathering and inter-personal public engagement activities in Japan. As foreigners are classified as the most vulnerable to disaster in Japan, it is important to understand how these restrictions will/are affecting the efforts of integration and disaster preparedness, which are a crucial part of the Government’s effort to reduce casualties and damage in the anticipated Nankai megathrust earthquake. Besides the results being useful for government interventions, it also adds to the knowledge of the repercussion of COVID-19 and how to plan for emergencies.

This study aims to demonstrate the effectiveness of investment in flood protection by analyzing the flood disaster caused by Typhoon Hagibis in Japan in October 2019. The typhoon severely damaged the central and eastern Japan regions and threatened the Greater Tokyo area.

The paper examines flood risks in the Greater Tokyo area and reviews how the flood protection systems functioned to protect Tokyo from the typhoon. The hydrological data of rainfall and water levels at major rivers and the operation records of flood control facilities are collected and analyzed.

The study’s major finding is that the flood protection system succeeded in protecting the Greater Tokyo area from flooding. Typhoon Hagibis maintained its power until landing because of climate change and caused record-breaking rainfall. In a worst-case scenario, thousands of people could have died and hundreds of billions USD worth of assets could have been lost in Tokyo.

The paper describes the actual effects of the flood protection systems, consisting of dams constructed upstream, reservoirs midstream and diversion channels downstream. Thus, this study’s findings directly relate to practical implications for other countries and cities, which face flood risks under a changing climate.

The paper highlights the importance of investing in flood protection by examining actual disasters and providing detailed descriptions of flood protection systems.

Based on a case study of the pre-2020 Olympics renewal project in the city-center of Tokyo, this chapter examines the nature and impacts of urban renewal conducted by the Tokyo Metropolitan Government (TMG) in relation to social housing.

A qualitative case study approach is used based on interviews (with different stakeholders), and participant observation (at various local events or public assemblies) to analyze the impact of such urban renewal on social housing and its community.

The TMG has promoted urban renewal of city government-owned land in public-private partnerships by defending these projects as “win-win-win strategy among residents-business-city.” However, at the same time it has worsened the housing conditions of residents by causing their displacement or the deterioration of their housing environment.

The chapter shows us that the TMG’s justification for the urban renewal — would produce trickle-down effects and help the residents — doesn’t reflect what is really happening to the community. This will help us to have a better understanding of the reality and to critically discuss a more just urban and housing policy.

The chapter provides a complex insight on the “super-residualization” of social housing in Japan, characterized not only by the decrease in its number but also urban renewal providing business services and amenities for the middle and upper classes. This provides an interesting comparison with Western societies.

Houses are durable, so an imbalance between demand and supply occurs after time has passed since initial construction. The purpose of this study is to quantify the extent of this imbalance for existing houses, focusing on the heterogeneity across property segments.

This study uses a unique data set on the “inquiry volume” that each property received from an online real estate portal to measure the volume of demand in relation to supply. Simple regressions are conducted in the resale condominium market across the Tokyo metropolitan area.

The inquiry volume successfully tracked a recent expected trend in which demand relative to supply is stronger for condominiums in reasonably priced areas, condominiums in convenient, accessible locations, condominiums built within the last 20 years and compact and spacious units. This study also confirms that these trends cannot be captured through heterogeneity in price levels, which has been widely used in previous studies on measuring housing preferences.

As an indicator of conditions in the housing market, the property-level inquiry volume has strong potential to provide useful information for supply strategies and for the sustainable use of existing housing stocks.

The originality of this paper is the use of information on the buyer side, which is typically unobservable.

This paper aims to shed light on current initiatives of urban regeneration around the Shibuya Station area within the context of contemporary Tokyo’s place development strategies. The objectives are twofold: to illustrate the characteristics of the plans and the planning approaches framing the interventions; and to identify the strategies employed to reshape the cityscape.

Using a case study approach, this paper combines data from historical and archival research, as well as policy documents and plans. These are supplemented by data from extensive fieldwork undertaken between 2015 and 2019 to critically assess and interpret the implemented policies and the outcomes of the regeneration.

The paper provides insight into the ongoing urban regeneration around the Shibuya Station area and identifies five key themes that summarise the strategies employed to transform the urban landscape in the area. Despite the apparent success and some innovations introduced by the redevelopment project, critical issues remain–especially around the privatisation of public space and the lack of a holistic approach to sustainability.

The paper examines a significant and timely case of urban regeneration. By critically discussing the implications of the redevelopment around Shibuya Station in the context of Tokyo’s current place development strategies, the study highlights the importance of an inclusive notion of sustainable development and contributes to the debate around Japanese urbanism and urban regeneration.

The purpose of this paper is to introduce a volunteer network from the Tokyo Metropolitan area that addresses the urge for senior citizens to stay mentally active and provide a possibility for them to participate in intergenerational contact as to feel included and useful to society.

The research derives from literature review, local government documents and online presentation as well as an interview that has been conducted by the Tokyo senior information site.

The REPRINTS (Research of Productivity by Intergenerational Sympathy) network in Tokyo is but one answer that combines a mentally challenging activity with intergenerational contact. The network presents an easy to reach and easy to implement diversion for schools to enable children to experience the traditional form of storytelling and help senior citizens to feel challenged and needed.

Learning from the experience of the REPRINTS network could help to set up similar activities in other communities that deal with the same problems and are seeking ways to include senior citizens, help them stay active and useful for the community and encourage intergenerational contact.

Japan is one of the forerunners when it comes to aging population. Yet, most research still focusses on the challenges, care and especially problems that occur in dying rural areas. This paper instead tries to take a more positive look to the future and concentrates on urban life and its context.

This chapter examines the issues of the low-cost carriers (LCCs) in Japan and their impact on the domestic and international aviation markets. “Genuine” LCCs, such as Peach Aviation and Jetstar Japan, began their operations in 2012 to follow the new movement of low-cost and low-fare airlines, which are different from the “new emerging” airlines, such as Skymark and AIRDO that appeared in the late 1990s. We discuss the recent history of LCCs in Japan, the characteristics of each LCC, the competitiveness of the high-speed railway in the domestic market, the impact of open sky policies, and the contribution of inbound foreign visitors to the international passenger volume increase. As LCCs in Japan have recently begun operations, they can continue to play a significant role in the Japanese aviation market.

Tokyo is the most populated urban area in the world, with a population of 36.5 million. The sheer number of people creates a wide variety of living environments for its residents to choose from. Using a questionnaire survey dataset with 4,120 respondents, this chapter examines the impacts of individuals’ attributes on their preferences to various quality of life (QOL) factors, as well as whether the actual choices of residential districts reflect their preferences.

Individuals’ attributes such as sex, age, marital status, the number and ages of children, and income affect the emphasis that they place on choosing a place to live. Although parents with school-aged or smaller children place a greater emphasis on childcare/school services, natural environment, public services, working communities, and moderate consumer price in local shops; young single white-collars tend to trade safety and environment for shorter commute and therefore select places high on access-related attributes.

For QOL factors such as the public transit, access to work, natural environment, and clean air/water, satisfaction levels show clear geographical patterns and access-related factors earn high scores in the city center, whereas the nature-related factors are higher in the suburb. In these attributes, correlation between city residents’ emphasis on these attributes and satisfaction scores are high, suggesting that people can successfully choose the place of living according to their emphases.

For other factors, such as childcare/education and other public services provided by the municipalities, residents’ preferences for, and the city's offerings are rarely aligned. One possible reason is that the information on the level and availability of these services is difficult for prospective residents to know. Therefore, public resources should be targeted to solve this mismatching problem through (1) raising the quality of services in areas where the need is prevalent but the satisfaction level is low and (2) providing more information on the level of services that each municipality is offering, to allow prospective residents to choose the right place that meets their need.

This chapter examines the airline performance effect arising from collaboration between airlines and high speed railway (HSR). The analysis presents scenario simulations using a bi-level model, which takes into account the effect of competition among airlines and HSR. Using real data, we examine the Japanese domestic market and the Japan-based international market: the markets consist of Tokyo Metropolitan Area, Osaka Metropolitan Area, Seoul/Korea, Frankfurt/Germany, Paris/France, London/United Kingdom, and Los Angeles/United States. Analysis of the domestic market assumes airlines and HSR compete against each other, and analysis of the international market assumes airlines only compete with each other. Initially, we conduct performance analysis using a simulation that mimics the current relationship between airlines and HSR. Then we present three scenarios for different combinations of collaboration between airline and HSR based on airline alliances. The results from this exercise are then used to examine the impact of the collaboration on the profits of airlines and HSR, passenger’s utility, and the network design of airlines. Last, we show the potential benefit to airlines – profitability, market share, and demand growth – from the airline-HSR collaboration. Our model shows that in Japan: (1) Airlines can improve their profitability in international operations by the collaboration with HSR when airlines set their hubs so they can connect to HSR; (2) The airline which has a lower unit operating cost than rivals and sets its hubs to connect to HSR can improve its joint profit with HSR through collaboration; (3) Airlines that don’t operate domestic flights and don’t set their hubs to connect to HSR encourage increased fare competition by coordinating with HSR, but their profit decreases. Whether these results are generalizable to other regions should be the subject of future study.
