Since this manga shows lots of staff that are reflecting Japanese cultures, traditions, etc., if you notice anything and would like to add some info on it that may be useful to some readers, please post here.
Also, if anyone finds some stuff that's puzzling in the chapter, and that may be related to some Japanese culture/tradition, etc., you can try posting here and asking, and hopefully, one of our members can provide some answers, clues, and/or related info.
To start off, a few things from chapter 1:
* About the difference between Hachiken and others on how they were admitted to the Dai-Ezo Ag High school
First, quick info on Japanese school system:
It starts at age 6, with mandatory 6 years of Elementary school, followed by mandatory 3 years of Middle school.
After that, majority of them go on to 3 years of high school. .... <To be continued>
* About the tradition for "first born son": <work in progress... I got to go and take care of other board stuff now. xp Be back later and add more info... meantime, if others find more stuff please feel free to add your post! ^^ >
From chapter 4:
It's the week of April 29 into the first week of of May when people in Japan get a string of National holidays, starting from Showa Day (late Showa emperor's birthday) on April 29th, then Constitution Memorial Day on May 3rd, then Green Day on May 4th, and Children's Day on May 5th. Combined with the Sunday and Saturday that falls in between (if any of the holiday falls on Sunday, then they get the following Monday off for that) they have a nice long holidays. Schools are off, most of the companies and offices are off. For students it's sort of like "Spring Break" in U.S., or "Easter Holidays" for some, except, for this, in Japan, most adults get holidays also, and this falls on nice Spring season also when it's not too hot, not too cold, nor rainy season like in June, and hence many families take family vacation trips or plan other family activities for this week... I think. ^^
