Everyday, a tune lasted for 1 minute is played through a huge speaker set outside the company building. Even though the windows were tightly shut and people were talking, a certain broadcast still can be heard faintly (it can be heard louder when it is autumn or winter — the windows were opened to allow cool air to flow in).
The first tune, an instrumental version of Yuuyake koyake 「夕焼け小焼け」 (“Sunset”, a Japanese kids song, shown below), is played at 4:45 p.m.. A broadcast is also included by the local municipal council while the tune is being broadcast, announcing that it is almost 5 p.m., and urging kids to go back home as well as asking the locals to look over the kids as they went home.
I also noticed that the time the tune played changes over season. As night fell earlier in the autumn and winter, the Yuuyake koyake tune is played at 4:30 p.m. during autumn , and 4:15 p.m. during winter.
Whenever the tune is being played, it is also an indication that it’s almost time to go home (not quite so in the winter). I felt relaxed and became slightly energetic as I continue pounding the keyboard throughout the afternoon. When the need for overtime work arose, it essentially became my motivation for the dusk.
Gaijinpot blogged that Yuuyake koyake is a tune being broadcast everyday through the speaker systems being set up. The purpose of the speaker systems is to convey disaster information to the residents, but when there is no disaster (thankfully), the relaxed tune will be played instead.
This system is widely applied across country, and the period of the tune being broadcast varies between region, typically between 4 p.m. to 6 p.m..
At 5 p.m., another tune unique to the region where I worked at, Yuube hoshi 「夕べ星」 (“Evening stars”, shown below) played. The atmosphere and the tune in its entirety was very relaxing; as if the stars in the sky can be brightly seen. Nevertheless, it marked the last 20 minutes before calling it a day. Update: noteworthy – this tune only plays at Wednesday.
At days other than Wednesday, the Narashino city song (orgel version) is played instead in the 5 p.m. slot (shown below). Nevertheless, its unique variation also appealed me.
In the place where I stay, the tune played at 5 p.m., titled No bara 「野ばら」(“Wild rose”, shown below). I found it amusing that different places and regions have their own variation, like the train jingles.
When these tunes were broadcast in the weekends, it signified that the day is almost over. Depending on the day and context, either I happily pack up for the day, or quietly prepare for the new day ahead.
