Summary

documented The conventional mapping is that Asahi and Mainichi are liberal/left-leaning and Yomiuri, Sankei and Nikkei conservative/right-leaning.2 documented This is not merely reputational: Kaneko's study collected 2,211 Constitution Day editorials from 50 papers (national and regional) across 1970–2019 and coded their left–right ideological tone, finding the axis real and persistent.1 documented The same study finds that the direction of movement over the period was conservative, not liberal — Yomiuri shifting toward constitutional revision from around 1990 under the rise of international-contribution arguments.1

Where each title sits

Position Title
Furthest left (national) Tokyo Shimbun (regional, Tokyo)
Left / liberal Asahi Shimbun, Mainichi Shimbun
Centre Nikkei
Right / conservative Yomiuri Shimbun, Sankei Shimbun

documented Below the dailies, the weekly-magazine spectrum runs from Shukan Kinyobi on the left, through Shukan Asahi / Gendai / Post as liberal, to Shukan Shincho as conservative, with Shukan Bunshun positioned as non-aligned and primarily investigative.3

The local-paper caveat

documented A substantial share of regional papers run editorial drafts supplied by the Kyodo wire service rather than original pieces; Kaneko's method detects this by measuring sentence-level similarity between same-year editorials across papers.1 documented The political consequence is that conservative critics describe Kyodo's drafts as a left-leaning influence propagating nationwide, while a pacifist critic has separately complained that dependence on the drafts makes regional editorial positions formulaic.1 Both complaints describe the same fact from opposite ends.
