I'd never heard of Taniguchi until seeing a panel from this book in the beautiful 1000 Years of Manga. Originally published in 1992 in Japan, this book has only recently become available in European languages thanks to a Franco-Spanish publishing collaboration to foster something they are calling "nouvelle manga." The idea is to rescue some of the more thoughtful "slice of everyday life" Japanese comics from the manga ghetto, presumably so they can reach a more sophisticated adult audience. The eighteen stories collected here embrace a quiet sensibility along with a realistic European art style.
Like Herge's famous Tintin series, the people are somewhat cartoony but all the other elements, from clothing, nature, and cityscape are richly detailed and precise. However, unlike most comics, there's no real story being told -- it's all about time. The salaryman who navigates the mostly wordless pieces is intent on savoring his surroundings, taking the time to notice the miracles of nature that unfold all around us all the time, and the brief encounters with strangers that can connect us to the larger spirit of humanity -- if we take the time to engage.
However, it would be an oversimplification to say the book is a celebration of "stopping to smell the roses," because the salaryman is both observative and curious. He goes for long walks, often alone, sometimes with his dog Snowy (perhaps a direct reference to Tintin?), and ever so often, with his wife. On these walks, he exhibits an almost spiritual communion with nature -- he's always running his hands through leaves, admiring gardens, letting the rain fall on him, floating in water. Although never made explicit, the connections with Shintoism appear to be quite direct. One thing is for sure, after you read this -- or rather absorb the art within the crisply controlled panels -- you won't walk anywhere the same way for a while.
