About OPODIS 2023

OPODIS is an open forum for the exchange of state-of-the-art knowledge concerning distributed computing and distributed computer systems. All aspects of distributed systems are within the scope of OPODIS, including theory, specification, design, performance, and system building. With strong roots in the theory of distributed systems, OPODIS now covers the whole range between the theoretical aspects and practical implementations of distributed systems, as well as experimentation and quantitative assessments.

Venue location info

OPODIS 23 takes place in West Area, Building 9, Multi-Purpose Digital Hall. The reception (Dec. 5) is at Tokyo Tech Front, Royal Blue Hall. MAC 23 (Dec. 9-10) is organized in West Area, Building 8E, 10th floor, Conference Hall.

Most attendants will arrive from Ookayama station (Meguro line, Oimachi line) and enter the campus via the Main Gate. Those coming from Midorigaoka station (Oimachi line) will come via South exit, through the bicycle parking and enter the campus via the Midorigaoka Gate.


  • Wifi: eduroam is available throughout the Tokyo Tech campus.
    If your institution does not support eduroam, we can create guest accounts on site.
  • Power plugs: Japanese power plugs are type A (2 flat pins; similar to USA). Voltage is 100V.
  • Display: the conference room uses HDMI connectors. USB-C adapters will also be available.
  • IC card: public transport uses any card of the Suica/PASMO family (interoperable).
    Those with an iPhone can create a card in the wallet app.
    Otherwise, it is highly recommended to buy a Welcome Suica card at the airport upon arrival.
    The card can also be used as an electronic wallet in many shops and vending machines.


Travel and accommodation information for conference attendees.

By train

From within Japan, it is easy to reach Tokyo by bullet train (shinkansen). Google maps provides reasonably good advice for connections. Coming from Western Japan, the most convenient is to leave the shinkansen at Shin-Yokohama Station and change to the newly opened Tōkyū Shin-yokohama Line.

By plane

Tokyo has two major international airports: Narita and Haneda.

  • Haneda airport (HND) is the larger of the two airports and better connected for local transport (e.g., Keikyū line). Most domestic flights and multiple flights to Europe and Asia land at Haneda airport.
  • Narita airport (NRT) is farther away but this is aleviated by the Narita Express train that stops at Musashi-Kosugi station, as well as the Keikyu lines that run between the two airports and stop at Shinagawa station. Most flights from North America land at Narita airport thus leaving less choice.


Tokyo offers a large variety of accommodations for all budgets and preferences. We recommend booking a hotel close to one of the stops on the Meguro line, Oimachi line, Ikegami line, or Toyoko line. Areas convenient for commuting to the venue are near the following stations: Oimachi, Meguro, Jiyugaoka, Musashi-Kosugi, Futako-Tamagawa. Other alternatives include: Shibuya, Ebisu, Shinagawa, Gotanda, JR Kamata.
The top recommendation is Meguro Station as this runs against the flow of the morning rush hour. Besides, the OPODIS banquet will be located near Meguro station
