A tool to check train seat availabilities

Unlike the thorough Deutsche Bahn site in Germany, there is no train seat booking sites in English besides the one offered by JR East. However it covers only the Shinkansen and limited express trains mainly running in the Northern Japan where not many tourists from abroad are interested in.

JR East booking site

Seems many tourists intend to travel Tokyo and Western Japan such as Kyoto and Hiroshima. The thing is that most people have no means to make train seat reservations until they come to Japan for the Tokaido-Sanyo Main Line Shinkansen, or for other trains to popular destinations such as to Takayama. I presume many people plan to utilize the Japan Rail Pass.

Even though you can't make reservations, there is a way to search train seat availabilities online beforehand.

JR Cyber Station site

If your computer recognizes Japanese characters, and you'd like to check vacancies on the trains running in Japan in advance by yourself, you might give it a go by following my directory.

==Update on 29th June 2011==

New Shinkansen train names such as Mizuho, Sakura, Hayabusa have been added in the list below.

1st line; asking you to choose one of them below
2nd line; Nozomi, Hikari, Mizuho, Sakura and Tsubame
3rd line; Kodama
4th line; Hayabusa, Hayate, Yamabiko, Nasuno, Tsubasa and Komachi
5th line; Toki, Tanigawa ans Asama

7th line; Choose here if you aren't traveling on Shinkansen, e.g. (limited) express trains e.g. Hida for Takayama

If you choose from between 2nd and 6th lines, station names will appear automatically in Japanese.They are all Shinkansen stations.

乗車駅・降車駅 / Choose the original and destined stations, and press the blue icon.
Fill the blanks in case you will take some other train than the Shinkansen.
Then the result will come up.

Typical names of the stations tourists are likely to use:
東京 / Tokyo
品川/ Shinagawa
新横浜 / Shin-Yokohama
小田原/ Odawara (Gateway to Hakone)
名古屋 / Nagoya
京都 / Kyoto
新大阪 / Shin-Osaka
姫路/ Himeji
広島 / Hiroshima
博多/ Hakata (Fukuoka)
熊本 / Kumamoto

I now try to check the Shinkansen ordinary class seat availability for 9th August from Tokyo to Kyoto.
The results are:

08 月 09 日　東京　→　京都　/ On August 9th, From Tokyo to Kyoto

Man taking a seat = reserved seat
Clover in green color = Green class
'B' in the bed = B (second) class sleeper berth

Remarks below:

○：空席があります。--Vacant
△：空席が残りわずかです。--Nearly full
×：満席です。 --Full
－：該当する席はありません。または予約できません。 No service on that particular train (e.g. Green car seats), or unable to book.
＊：喫煙席はありませんが、喫煙ルームが設置されています。--No smoking allowed in all seats, but there are designated smoking areas on some of the carriages. (Shinkansen series N700)

So as of today ( 30th July, 2008 ), most of the non-smoking ordinary reserved seats on the Tokaido Shinkansen leaving Tokyo between 8 and 9 am on 9th August are fully booked.

Another example is the limited express Hida from Nagoya to Takayama at 6:00 am on 9th August. Choose the date, departure timeut the original and destined stations in the blanks.

Station names in Japanese:
名古屋: Nagoya
高山: Takayama

The results are as below.

08 月 09 日　名古屋　→　高山 / On August 9th, from Nagoya to Takayama

As of today ( 30th July, 2008 ), many of Hida trains are still vacant.

Last example is an overnight sleeper train 'Hokutosei' from Ueno to Sapporo. Try to search vacancies for the same day as above cases.　The departure time should be chosen as 19:00

08 月 09 日　上野　→　札幌 / On August 9th, From Ueno to Sapporo
