Periods of Japanese history (not a single line)
A timeline of Japanese historical periods that refuses to be a single line: the Warring States era sits inside the Muromachi period for 106 years, two imperial courts ran in parallel for 56, and the two famous boundaries — the founding of the Kamakura shogunate and the turn from Edo to Meiji — are drawn as hatched bands of years rather than as a date, then enlarged below.
This drawing comes from one YAML file. No shape was moved by hand.
Notes in the source (in Japanese)
年表は一本の線に見えるが、実際は重なっている。
戦国は室町の中にある。 応仁の乱(1467)に始まるが、室町幕府は 1573 年まで続く ——106 年ぶん重なる。 幕末(1853〜1868)も江戸の中。
南北朝の 56 年(1336〜1392)は、朝廷が 2 つあった。京都の北朝と吉野の南朝。足利義満の仲介で後亀山天皇が京都へ入り、合一する。
鎌倉幕府の成立は 1185 と 1192 の両論。守護・地頭を全国に置いた年か、征夷大将軍に任じられた年か。教科書は 1 点に決めない方向へ動いている ——東京書籍は 2012 年度から年表を 1185 にして「諸説がある」と注記、帝国書院は 1180 年(侍所)から段階的に整ったとして、平安と鎌倉の境を斜め線で描く。出典:帝国書院 Q&A https://www.teikokushoin.co.jp/junior/faq/detail/941/ 取得 2026-09-29(東京書籍の件は二次情報で、東京書籍の一次資料は確かめていない)。
幕末も、切り替わった 1 点は無い —— 大政奉還 1867・王政復古 1867・戊辰戦争 1868〜69・版籍奉還 1869・廃藩置県 1871。
全体は 1px = 0.96 年なので、15 年は 16px にしかならない。帯の中に字が入らない所は、下に拡大図を置いた(②③)。年表の常道。
目盛の線は帯の中だけにしてある。下まで伸ばすと、出来事の字を貫く(実際に貫いた)。出来事の名前は段をずらす —— 幕末は 4 年に 4 つ集まるので、同じ段では必ず重なる。

A fridge does not make cold, it pumps heat out — and it throws away more than it took, because the compressor's electricity comes out as heat too
Heating and cooling swap the roles of the indoor and outdoor coils, and the only part that changes is one valve — which is also why a heat pump briefly runs cooling in the middle of heating, to melt its own frost
