Fujimi · 富士見 · the mornings Tokyo saw FujiSince 1963 someone on the rooftop of a school in Kichijoji has looked west-south-west every morning at 9 and written down whether Mt. Fuji, 83 km away, was visible to the naked eye. Since 1894 the weather office in Kofu has written down the day the first snow appeared on the summit. This is both records, drawn as one mountain.1963Year2023Pale mountain = the icon, as clear as that year's count. Rows = one per year, width = mornings. Light rows = under 100, the 1877 count.

Not "was looked at" and not "could be seen" — the mountain either showed itself that morning or it did not.見るみるto look at — you choose to富士山を見る ふじさん を みる見えるみえるto be visible — it shows itself, no choice involved富士山が見える ふじさん が みえる見られるみられるto be able to see — you have the chance富士山が見られる ふじさん が みられるSaid politely, the sentence this whole page is: 今朝は富士山が見えました。 けさ は ふじさん が みえました — "Fuji was visible this morning."N5natureI can see mountains over there from my window.Neutral窓(まど)から向(む)こうに山(やま)が見(み)えます。Casual窓(まど)から向(む)こうに山(やま)が見(み)える。Vocabulary窓window向こうover there; the other side山mountain見えるto be visible; can seeGrammar〜が見える~ is visible; can see ~Try in JIVXN2natureMt.

The observatory publishes a chart, not a table, for these years. We read marker positions off it; checked against the 31 tabled years, 28 land within 0.5 day and three (1970, 1972, 1973) are merged-marker misses where the two lines cross, so those come from the table. Every digitised row is labelled as such below and in the CSV. If Seikei supplies the table, these rows are replaced.Two rooftops. The Tokyo Metropolitan Government has counted from Tocho at 9 a.m. since FY1992 (and from the 36 m JMA building in Otemachi at 10 a.m. before that — a different sky, never compared). Its numbers are not Seikei's numbers; the year cards from 1994 on use Tocho's months and say so.First snow. Kofu Local Meteorological Observatory, by eye, 1894–2025; the date is the first cap after the summit's daily-mean temperature peaks, which is why the Sep 7 2021 sighting was revised to Sep 26. From the 2027 season the JMA judges it from analysed snow depth and says the two are not directly comparable, so this record ends at 2025.What the paper says causes it, quoted. The jump in 1973 follows the oil shock (64 mornings in 1972, 78 in 1973). The recovery after 1980 is not pollution alone; the paper names drying and heat-island circulation as candidates. Visibility worsens through the day, so the count is taken in the morning. Eastward targets are back-lit, so the Tower and Fuji counts are not directly comparable.
