Our film follows the track of the father-daughter relationship evolving over twelve years as they commute to work and school on the same train on the Sotetsu Line. The entire story is set on a train and was filmed in one shot.

As the daughter grows, she explores new social values, ventures beyond her family circle, and becomes distant from her father. The ever-changing father-daughter relationship throughout the years is styled as a seamless time-lapse sequence of 50 lookalike actors with train's winding movements to express the swaying emotions of the two. It reflects how life goes by in a succession of ordinary moments like an uncut one-shot film.

In the final scene, the father prepares to get off at their usual station, except this time, the daughter will continue on to her new university in Tokyo. She is on the new connecting line that goes directly into Tokyo.

SOTETSU is a Japanese railway company operating entirely within Kanagawa Prefecture, which neighbors Tokyo, since 1917. In March 2023, it established a direct through service to central Tokyo by connecting with the Tokyu Line.

Our mission was to promote the newly-opened link to families and potential families, showcase how it provides transfer-less access from the Kanagawa suburbs to downtown Tokyo, and present it as a place for families to settle down. Our idea draws from two perspectives relevant to the brand purpose of supporting local lifestyles.

The first is to celebrate the beauty of ordinary family life: The Sotetsu Line isn’t for temporary events. Instead it’s a long-standing vital infrastructure that supports the everyday lives of its passengers, particularly families.

The second is to celebrate the newly-extended potential of those living along its lines: The direct connection to Tokyo expands their scope of activity and opens up new possibilities.

We concentrated on shooting a time-lapse sequence of 50 actors on a hand-powered train in one continuous shot. This meant that high-level VFX techniques were crucial in creating the train's interior art and the background outside the train.

The biggest challenge we faced was the tracking required for compositing due to the unpredictability of various factors, such as the actors, art set, and camera movements. Although we used high-precision laser scanning and fixed tracking markers on the train set, we could only achieve around 50% accuracy. Therefore, we had to manually adjust the tracking for each frame, which took us a month to complete.

By flawlessly compositing the one-shot footage, the live-action footage of the train's interior and exterior, and the CG models we had created, we succeeded in producing a visually stunning final product that was both cohesive and seamless.

Season:

The direct connection opened in March, which, in Japan, is the season for graduation and the start of new careers. It’s a season that the Japanese feel about and associate with new beginnings. In addition, this spring also marks a return to normalcy from the COVID-19. (In fact, three days before our launch, the long-standing mask requirement was discontinued in line with government policy.) That's why we celebrate the thrill of going out to new places.

Music:

We sampled and mashed up two Japanese songs and connected them into one track like a train. The first is "Family Scenery", a folk masterpiece with the theme of "family" released in 2002. The other is "On A Time Machine", a hip-hop masterpiece with the theme of "time" released in 2017. The train of songs from different eras with a pair of themes tells a timeless father-daughter story running through the years.
