I remember it, solely from Mangajin... 大東京ビンボー生活マニュアル。
Dai-Toukyou Binbou Seikatsu Manyuaru... Manual for living "poor" in Greater Tokyo.
I've only encountered a few isolated panels that generally have to do with the main character watching video tapes, or going to a rugby game, or eating this or that food...
One strip strip (as mentioned) has the character going on a video-holiday, while his friend is in cram school, where he stays up and watches all of his friend's video tapes (rather than paying to see a movie obviously...), etcetera.
Although Dai-Tokyo's main concern may be entertainment and political statement, it also serves as a how-to guide for pulling off a successful and happy poor lifestyle.
At present, while 95% of the commercial message in Japan is to buy buy buy, borrow borrow borrow... It may be difficult to sit there and imagine a
shiawase binbou seikatsu...
It's no fun eating at 99en shop... Area, a publicaton in Japan published a more curious editorial on the
"benefits of being poor"... About how a simple impoverished lifestyle was somehow honourable & meditative, and how they "love the poor!"
Bah... this manga is of course, not so indideous!
ed: I'll add that (like a lot of manga from Mangajin) that the original publishing date for this manga is the mid-eighties, when the economic situation in Japan was very different--- Japan was still in its bubble-era, during initial publication of this serial, and the idea was probably more of the case of rejection of wealth, rather than the pragmatism of dealing with the lack of it due to economic failures...
I can't comment really on the whole socio-political statement of this manga, but that's my guess, for the time frame it was published.
