The Fifth World Landslide Forum (WLF5) was organized on 2–6 November 2021 in Kyoto, Japan. WLF5 was initially planned to be organized on 2–6 November 2020, and the Kyoto Landslide Commitment 2020 was planned to be launched in November 2020. Due to the COVID-19 pandemic, we had to postpone WLF5 by one year to November 2021. However, the launching of the Kyoto Landslide Commitment 2020 (KLC2020) and paper submission for WLF5 proceeded as initially planned. Two thematic issues of Journal “Landslides” titled as “Sendai Landslide Partnerships 2015–2025” were published in October and November 2020. The launching session of the Kyoto Landslide Commitment 2020 was organized on 5 November 2020. After the greeting sessions and panel discussion, the Kyoto Landslide Commitment 2020 was launched by all participants from 90 signatory organizations (Sassa 2021a).

The papers submitted to the six themes of WLF5 were reviewed, revised, accepted and published in six volumes of books, “Understanding and Reducing Landslide Disaster Risk,” (Vol.1-Vol.6) in January 2021. Organization of WLF5 progressed during 2021 with hopes of a primarily in-person event. However, the COVID-19 situation around the World and in Japan did not allow the face-to-face conference even in September–October 2021. Then, the Organizing Committee of WLF5 decided to organize the Forum in a hybrid mode (onsite, online-virtual, and pre-recorded modes). This Preface reports the greeting session and the high-level panel discussion “Review of KLC2020 and the way forward” in the hybrid Fifth World Landslide Forum-Implementing and Monitoring the Sendai Landslide Partnerships 2015–2025 — Voluntary contribution to the Sendai Framework 2015–2025 and the Agenda 2030-Sustainable Development Goals. Other activities including the list of all speakers, countries, and presentation titles in parallel sessions are reported in the category of News/Kyoto Commitment.

The maximum number of participants are from Japan was 215. Due to COVID-19, no person from foreign countries/regions attended WLF5 in Kyoto, Japan.

High-level panel discussion “Review of KLC2020 and the way forward” on 3 November 2021

The Kyoto 2020 Commitment for Global Promotion of Understanding and Reducing Landslide Disaster Risk (Kyoto Landslide Commitment 2020: KLC2020): A Commitment to the Sendai Landslide Partnerships 2015–2025, the Sendai Framework for Disaster Risk Reduction 2015–2030, the 2030 Agenda Sustainable Development Goals, the New Urban Agenda and the Paris Climate Agreement was launched on 5 November 2020 by the adoption of 2020 Kyoto Declaration at the end of the launching session. One year has passed after the launching of the KLC2020. At the Fifth World Landslide Forum, a high-level panel discussion reviewed the progress of KLC2020 and strategized the way forward by inviting panelists from ICL supporting organizations (UNDRR, UNESCO, WFEO, IUGS, and IUGG), three ICL full members, and one ICL supporter.

At the beginning of this session, two forum chairs (Immediate Past-president and Executive Director of the ICL) presented opening greetings. Under the chair from the Global Promotion Committee of IPL and the KLC2020 Secretariat, firstly, Secretary General of KLC2020 secretariat presented a keynote speech “Review of KLC2020 and a new open access book series for KLC2020.” Nine panelists, as described below, presented talks on different aspects. At the end of the panel discussion, Satoru Nishikawa (Nagoya University) from the floor addressed the significance of this new open access book as a platform for practitioners and proposed to organize a side event in the coming Global Platform for Disaster Risk Reduction in Bali, May 2022.

Sálvano Briceño (First Chairperson of the Global Promotion Committee of IPL (2007–2014), Former Director of UNISDR (Director of UNISDR in 2001–2011)) addressed the concluding remarks and stressed the significance of an intergovernmental cooperation framework on landslide risk reduction, hopefully to be incorporated into the Intergovernmental Panel on Climate Change.

An explanation to IPL, KLC2020, and the new Global Promotion Committee of the IPL and KLC2020

The Tokyo Action Plan was adopted at the United Nations University in January 2006. To promote the International Program on Landslides (IPL) along the Tokyo Action Plan, ICL exchanged a memorandum of understanding (MoU) with each of ICL supporting organizations of UNESCO, UNDRR (UNISDR), WMO, FAO, UNU, ISC (ICSU), and WFEO in 2006. An IPL logo (Fig. 2) including those organizations was agreed upon. The Global Promotion Committee of the IPL was established to manage the IPL with Sálvano Briceño (Director of UNISDR in 2001–2011) as the first chair of the committee. Following the launching of the Kyoto Landslide Commitment 2020 on 5 November 2020 and the launching of the open access book series for KLC2020 as a result of the high-level panel discussion on 3 November 2021, the Global Promotion Committee of the IPL has decided, on 26 November 2021, to extend it to manage the IPL and KLC2020, namely, the Global Promotion Committee of the International Program on Landslides and the Kyoto Landslide Commitment 2020 (IPL-KLC Global Promotion Committee).  The logo of this committee is shown in Fig. 2.
