家に帰らない男たち – Guys Who Don’t Go Home

Owing perhaps to what seems like a strong strain of introspectiveness, there are a lot of books in Japanese about what it means to be Japanese. They don’t get translated and seldom get any attention outside Japan though. Since I’m interested in both Japanese society and the language this suits me well. Anyway, I thought I’d do my part and write something about one of these books.


It’s called 家に帰らない男たち (Guys Who Don’t Go Home, roughly) by 松井 計 (Kei Matsui). The book is about men who don’t return home after work, many of them having a family that they only see on weekends.

The book has six chapters, each chapter focusing on one particular man and his situation. Following is an outline of the chapters:

  1. A Guy Who Don’t Go Home? A Guy Who Can’t Go Home?
    44 y.o. advertising agency worker
    Started not going home just after getting married and changed jobs, because he had to work late and the commute too long. Got divorced but still maintains the mostly unused house in the suburbs, two-and-a-half hours from his workplace. Sleeps in capsule hotels and likes to go out drinking on weekdays after work. Sees his kids on the weekends but always brings them to his parents home instead of the house they grew up in. The reason why he retains the house is something of a mystery.

  2. A Dreamless Person Chasing Dreams
    22 y.o. guy who does day jobs for dispatch companies
    Came to Tokyo to get “big”, but can’t really define what that means. Won’t return home until he’s “made it” in Tokyo. Says it’s important to be independent and take care of himself but still lets his parents pay the mobile phone bill. Sleeps at net/manga cafes. Seems generally quite stupid to me but the author stresses that he is at least polite.
  3. Going Home Is Scary
    43 y.o. salaryman
    Came from the countryside and made it as a sales guy in Tokyo. Has a home in the suburbs and a family. Gets on the train home every day, but when nearing his station, feels scared and gets on to the backwards-bound train into the city again. Says he doesn’t want to ruin the perfect balance of his home, which he thinks is what would happen if he was there on weekdays, but enjoys spending perfect weekends with his wife and kids. Sleeps at capsule hotels or saunas or, to save money, at the office.
  4. Weekend Marriage
    38 y.o. high-earning IT industry salaryman
    Spends only the weekends in the house with wife and daughter. Used to rent an apartment between the office and the house, but left it after realizing it was more fun to spend the night at saunas where he could chat with others. The weekend marriage is by mutual consent with the wife, whom the author also met and interviewed. Both enjoy this lifestyle, but are prepared to change it once the kid grows up and maybe starts thinking it’s odd.
  5. Has Everything, No Problems
    50 y.o. salaryman-turned-self-employed
    Formerly a salaryman who was stationed all around the country by his company, and even in the Middle East for a few years, but grew tired of that and started his own company with a friend. Lives quite close to the office, but still started to think it’s unnecessary to go home in the evening. Enjoys the communal aspect of staying at saunas. Kid has moved out. Returns home occasionally. Wife doesn’t seem bothered.
  6. A Double Life
    46 y.o. designer
    Grew up in the sticks where everyone was expected to become a factory worker/engineer, but went to Tokyo to go into design instead. Has wife and kids, but shares an apartment with his 21 y.o. hostess girlfriend during the weeks. Wife thinks he is working hard, or at least that’s what he thinks. Loves his family and realizes this can’t go on forever. The girlfriend is also interviewed and she seems to enjoy the situation. The girlfriend is otherwise the female equivalent of the guy from chapter 2.

Matsui frequently makes a point of having interviewed many people as material for this book. I think the men that this book centers around are all quite stereotypical and easily imaginable – but all with some disturbed psychological twist in their heads. I’m not sure if that’s because he incorporates material from other interviewees into these men, thus making them somewhat generic, or because he hasn’t actually interviewed many people at all, but just invented most of it. In any case, it’s an interesting read, not an academic paper.

From my own experience, I have heard Japanese coworkers say things like “the office/train is where I can relax”, claiming their houses (with wive, kids, and parents) are stressful. It’s not uncommon for Japanese office workers to spend all night at the office – it seems to give them credibility and respect among their peers too (despite being completely unproductive the following day). This book sheds some light on why. Saunas’ communal aspect, with people napping in reclining chairs in a common area, is one thing.

The language is quite simple: Not much specialized vocabulary outside of society-related concepts such as 脱サラ (quit working as a salaryman) and プータロー (loser). Grammar is about between JLPT level 2 and level 1. The author uses quite a lot of non-general use kanji, though, as well as kanji for words usually written in hiragana, and there is almost no furigana. Not because the vocabulary requires it, but because he just likes to, I suppose. That’s good for learning a little extra that probably won’t show up on a JLPT exam.

Anyway, this is the first of Matsui’s books that I read but it is unlikely to be the last. If you don’t know who he is, he’s famous for having been homeless, but he then wrote a book about being homeless and now he’s a successful author, writing mostly about typical Japanese social phenomena.


Jumbo Jets vs Embedded Software

A while ago I bought a book called 747: Creating the World’s First Jumbo Jet and Other Adventures from a Life in Aviation by Joe Sutter. Actually I bought it at Hong Kong airport to read on the way home – ironically not by 747 (I don’t know what kind of plane it was – so no, I’m not an airplane geek). I bought the book because I was curious to see if the reaction I’d get was “Oh, that’s exactly like in embedded software!” or “Oh, so that’s how they do it in aeronautical engineering!”. It turned out to be the former.

Joe Sutter, the author of the book (although he probably had a lot of help writing it), lead the engineering effort to design the plane, which does seem like the most interesting point of view to me. Beside the main story of how the 747’s design came to be, he also tells some quite interesting tidbits from the history of aviation and from the aviation industry. These fit in nicely and makes the pages fly by. Unfortunately, there are a few too many autobiographical digressions that I didn’t like, and also the literary quality of the book is very poor, with many repetitions, and sometimes even contradictions. Anyway, not bad for an engineer.

So yes, designing and delivering jumbo jets seems to be very similar to designing and delivering embedded software. The scales are, of course, completely different though. Not only physical scales – where they measure time in months and years, we measure in hours and days – and costs are similarly orders of magnitude higher in aviation.

What struck me as the biggest difference though, when I was sitting on a modern airliner somewhere over the South China Sea while reading the book’s introductory chapters on aviation history, was that the jet airplanes he described in the early 1950s (such as the Dash 80), are exactly the same as the jet airplanes now, 50 years later! They fly at the same speed, same altitude, and use basically the same engines. That’s really terrible! Commercial aviation has surely come a long way since the Wright Brothers flew, but it did so in the first 50 years of its history. I’m glad I work with software.


Even more sad is that even if you double the speed of an airplane, it would hardly make any difference today anyway. The Americans (I didn’t know that before reading the book), Europeans, and Russians all had their fun trying to make realistic supersonic commercial airplanes. But even if they had succeeded, how much of the total time spent traveling is really spent in the air, at cruise speed, anyway?

For example: from my home in central Tokyo to somewhere in central Hong Kong, which seems like a fairly typical scenario, the flight time is on average about 4 hours. Say you have to be at the airport 1.5 h before the flight, and it takes 1 h to get from the airplane out of the airport, 1.5 h for me to go to Narita airport, and 30 min to get to/from Hong Kong airport, and an extra 15 min in either end to go between stations/taxis etc – that’s 5 hours! So even if the speed of the airplane doubled, you’d only get between where you are and where you want to go 20% faster. No, if anything close to aviation, I’d like to be an airport architect, city planner, and anti-anti-terrorist consultant. That would speed things up.

PS. I always thought of the Jumbo Jet as the airplane with two floors, but a significant part of the book is spent revealing how it came to be that the 747 ended up basically not having two floors! How strange.
