VDD19

Welcome to Video Dev Days 2019

The VideoLAN non-profit organization is happy to invite you to the multimedia open-source event of the summer!

For its eleventh edition, people from the VideoLAN and open source multimedia communities will meet in Tokyo to discuss and work on the future of the open-source multimedia community.

This is a very technical conference, focused on low-level multimedia.

Traveling to Japan

You should consider staying a bit longer to Japan, if you can afford a few extra days.

You should take care of your passport and, if applicable, your visa very quickly!

Rémi has written a short guide about that: traveling advice for Japan.

Sponsorship for Japan

If you want VideoLAN to sponsor your trip, you should read the Sponsorship Policy.

Transportation

Be sure to get a Japanese electronic payment card to travel easily on the public transports. To get around on local transit, you can use Google Maps or other.

NOTE: VideoLAN does not refund taxi, car rental and public transport.

JR Pass

Depending on the length of your stay and that of your JR Pass, you might want to save it for outside the conference days.

Anyway, with a valid JR Pass, you can ride on the Tokyoite JR East services for free, notably the Yamonote loop and the Chuo-Sobu transversal train lines, by showing your pass at the manned gate, and JR-operated buses by showing your pass to the driver. Nevertheless you still need to pay on the metro and on private rail and bus lines.

Tokyo-Haneda (HND) airport transfer

From the airport to IIJ:

• Tokyo monorail from the airport to Hamamatsucho station.
• JR Yamanote line local train from Hamamatsucho toward Tokyo/Ueno to Akihabara station.
• JR Chuo-Sobu line local train from Akihabara to Iidabashi station.

Travel time: about 50 minutes.

Tokyo-Narita (NRT) airport transfer

From the airport to IIJ without JR Pass:

• Keisei Skyliner express train from the airport to Keisei-Ueno station.
• 600 meters walk south from Keisei-Ueno to Toei metro Ueno-Okachimachi station.
• Toei metro Oedo line to Iidabashi station.

Travel time: about 90 minutes.

You can buy advance Keisei train tickets online here at a slight discount. But if you really want to save, you should take the slower Keisei main line limited express train instead of the Skyliner.

For JR Pass holders, that is a alternate all-JR route:

• JR Narita Express train from the airport to Tokyo central station.
• JR Chuo line local train from Tokyo to Ochanomizu station.
• JR Chuo-Sobu line local train from Ochanomizu to Iidabashi station.

Tokyo central station transfer

If you come by bullet train:

• JR Chuo line local train from central to Ochanomizu station.
• JR Chuo-Sobu line local train from Ochanomizu to Iidabashi station.

or:

• Tokyo metro Tozai line from Otemachi to Iidabashi station.

Tokyo-Ueno station transfer

If you come by bullet train from North/East Japan:

• JR Yamanote line local train from Ueno to Akihabara station.
• JR Chuo-Sobu line local train from Akihabara to Iidabashi station.

Means of payment

VISA and MasterCard cards are not universally accepted in Japan. You will need to withdraw cash from an international ATM. You can find those:

• at the airports when you arrive
• in 7-11 convenience stores throughout Tokyo and other cities,
• and during office hours in Japanese Post offices.

Do not bother with to local banks ATMs, most of which are incompatible.

For day-to-day small transactions, you should procure a FeliCa electronic payment card. They can be used to enter and exit public transports (train, metro, bus, etc), to check out at convenience stores and many shops. There are two options in Tokyo area:

• the (free but time-limited) Welcome Suica card from any JR East Travel Service Center (including Narita and Haneda airports),
• the normal Suica card, or
• a Pasmo card.

You can charge the card with Japanese bank notes - not (directly) with your credit card.

For large transactions such as hotel bills, you can use your debit or credit card, which should be cheaper than cash withdrawal. We recommend to refuse direct currency conversion (charging in your home currency) if the merchant offers it.

If you want to be on the safe side, consider exchanging 20,000 or 30,000 JPY in advance from your local bureau de change. Be sure to compare fees and avoid airport bureaux as their rates are usually awful.

Power supply

In Tokyo the electrical supply is:

• Voltage: 100 V
• Frequency: 50 Hz

This is different from almost anywhere else, so check the specifications on your power adapters.

Also note that Western Japan uses 60 Hz, so look out for that if you will be going there too.

Electrical sockets

Japan uses Type A power sockets like North America. They are not compatible with European or Commonwealth sockets, so you may need to buy passive adapters BEFORE YOU COME to Japan. (In Japan, adapters will target Japanese going to Europe, not so much vice versa).

Internet

Please bring your own internet.
