20th International Symposium
on Very High Energy Cosmic Ray Interactions


Monday 21st – Friday 25th, May, 2018

Noyori Conference Hall, Nagoya University, Nagoya, Aichi, Japan


2nd Bulletin April 15th 2017


Dear possible participants,


On behalf of the Organizing Committee, it is our pleasure to announce that the 20th International Symposium on Very High Energy Cosmic-Ray Interactions (ISVHECRI 2018) will be held at Nagoya, Japan, May 21 - 25, 2018. We would like to invite you to attend the symposium and to contribute to the program. ISVHECRI is a biennial international conference series launched in 1980 at Nakhodka (Russia). The scientific aspect of the series is to focus on the high energy hadronic interaction of cosmic-ray particles and related topics including any high energy cosmic-ray research. The Symposium will highlight the understanding of hadronic interactions from cosmic-ray data as well as the studies of hadronic interactions at colliders and beam facilities, in particular at the LHC and RHIC. This symposium series serves to strengthen the interaction between accelerator-based and cosmic-ray communities especially with regard to very high-energy phenomena.

Date:         Monday May 21 – Friday 25, 2018   

Place:        Noyori Conference Hall, Nagoya University, Nagoya, Japan

Access and accommodation:

Nagoya locates at the center of Japan, and is very convenient access from elsewhere in Japan by public transportation such as the Shinkansen bullet train. It takes about 30 min. from the nearest airport, Central Japan International Airport, to downtown Nagoya by Meitetsu-line. Nagoya University locates at the east area of Nagoya city area. One can easily access the main Higashiyama campus via subway Meijo-line (Purple-line). There locates Nagoya-Daigaku (Nagoya University) station inside the campus. Noyori Conference hall is about 5 min. walk from the station. Though there are no near-by hotels in walking distance, there are many hotels of various classes around subway stations in the downtown Nagoya, such as Imaike, Chikusa, Sakae, Fushimi, Nagoya , or Kanayama stations, which are 15-20 min. via subway from the campus. An example of hotels can be found in the symposium web page.

    • The lecture titled with “Explore the invisible universe” will be for general Japanese audience in the Sakata-Hirata hall near by Noyori Confernce hall in the campus. The lecture will be in Japanese only. All the symposium participants are invited.
  • 23 May 2018 16:30 – 18:30 --- Tour for the emulsion facility in F-lab.
    • In parallel to the lecture, participants are offered to a short tour for the emulsion facility in F-lab of Nagoya University. Those who like to join the tour kindly asked to sign up in advance via indico registration page.
  • 23 May 2018 19:00-21:00 --- Banquet
    • Banquet will be held at Hotel Miel Parque Nagoya (
      The venue is “Zuiun(West)” at the 2nd floor. The hotel is just close at the subway station “Chikusa” of the Higashiyama-line (Yellow Line). It takes about 15 min. from the station “Nagoya university” by subway. Please be informed there will be no transportation service from the university to the hotel arranged by LOC.
