Today Square Enix kicked off the celebrations for the 15th anniversary of the Kingdom Hearts series by opening a countdown website and inaugurating a beautiful memorial clock in promenade of the Shinjuku station of the Marunouchi line in Tokyo.

The clock, that you can see in the gallery below, is made by a main quadrant plus twelve smaller stained-glass circles displaying the characters of the series, including a clock counting down to the midnight between January 11th and January 12th.

The clock appears to be based on your device's internal clock, so the time left will change depending on your time zone, but of course we should consider the one in Tokyo to be accurate.

January 12th marks the local Japanese release of Kingdom Hearts HD 2.8: Final Chapter Prologue, even if we don't know if something else will appear on the site when the time will expire.

The clock will be on display in Shinjuku only until January 15th, which is unfortunate, since I'll miss seeing it in person only by nine days.

That aside, you can check out a picture, a mock-up, and illustrations for all the stained glass designs in the gallery below.

The precise date of Kingdom Hearts' 15th anniversary will be on March 28th, since the first game was released in Japan on March 28th, 2002.  Director Tetsuya Nomura teased more information about Kingdom Hearts III coming during the anniversary celebrations some time this year.

Kingdom Hearts HD 2.8: Final Chapter Prologue will be released in the west exclusively for PS4 on January 24th.
