'The humanism that imbued all his work is familiar to his readers, but the man himself was much less well-known, naturally reserved in character and more inclined to let his work speak on his behalf,' it said. Casterman, his publisher, also praised Taniguchi's character, describing him as an 'extraordinarily kind and gentle' person. Taniguchi 'really did bridge the two worlds of cartoon art - Japan and France,' said Sebastien Langevin, a graphic art specialist and Canal BD Manga Mag chief editor.

'He was preparing a new work intended for family readership, a story in three volumes, 'The Millennium Forest,' in full colour, a new approach to manga,' his agent and translator Corinne Quentin told AFP in Tokyo.

Four years later, the annual cartoon festival in the French city of Angouleme held a retrospective of his work. In 2011, the French government awarded Taniguchi the Knight of the Order of Arts and Letters - one of the country's most prestigious prizes. 'He was seen by French readers, illustrators and publishers as a god, while he presented himself as a regular guy,' fellow manga artist Tori Miki said on Twitter. He became especially popular in France, one of the biggest markets for graphic art. Born in 1947 to a modest family in the city of Tottori, 100 kilometres (60 miles) northwest of the old imperial capital Kyoto, Taniguchi had his first cartoon published in 1970. 'Extraordinarily kind' - Taniguchi's detailed landscapes populated by vaguely cartoonish characters drew comparisons in the West with some of the better-known European comic heroes, such as Tintin. In works such as 'The Walking Man', the protagonist is occupied less by any specific action as with a fascination with aspects of everyday life - the things he finds, the scenes he sees and the people he meets on his strolls through suburban neighbourhoods. Critics have also praised his gentle subject matter for standing in stark contrast to the usual fare of high school romance or sometimes violent pornography consumed by some of Japan's manga fans. Taniguchi's work is hailed for its delicate line drawing and intricately-constructed landscapes. Just over a decade later, he hit the international manga scene with 'A Distant Neighbourhood', about a Japanese salaryman who travels back to his childhood - widely seen to this day as his masterpiece. Taniguchi first shot to fame in Japan at the end of the 1980s with the first volume of 'The Times of Botchan', which centres around Natsume Soseki, one of Japan's greatest writers. The artist's French publisher Casterman announced his death on its website, adding that he had been seriously ill, as it expressed its deep condolences to his family. Jiro Taniguchi, a legend in Japan's comic art of manga, died in Tokyo on Saturday at the age of 69, leaving behind an international following for his exquisite line drawing of scenes from everyday life.
