2025年4月29日（火）、午前3時に起きた。午前6時に家を出て、伊豆大島の元町地区を歩いた。その後、島内でドローンの操縦を練習した。
朝の散歩では、屋久島でよく見た植物に遭遇した。エゴノキ、トベラ、シャリンバイなどだ。屋久島と比べると、これらの花の開花時期は1か月ほど遅いように思う。
屋久島で見たことのない植物にも出会った。たとえば、白い花を咲かせていたハコネウツギ。森林総合研究所九州支所のウェブサイトによれば、この花の色は白から淡紅色、さらに紅色へと変化していくという。コゴメウツギも白い花をつけていた。この花も屋久島では見たことがない。
天気は快晴だった。元町港のあたりからは、天城山や大室山といった伊豆半島の山々、さらには富士山がはっきりと見えた。露天風呂に入っていた夕暮れ時にも、海の向こうに富士山を眺めることができた。
On Monday, April 29th, 2025, I got up around 3:00 a.m. and left home at 6:00 a.m. to walk around the Motomachi district on Izu Oshima Island. After that, I practiced flying a drone at a school on the island.
During my morning walk, I came across some familiar flowers I had known when I lived on Yakushima Island, such as Japanese snowbell, Japanese cheesewood, and Yeddo hawthorn. Based on my observations, these same flowers seem to bloom here about a month later than they did on Yakushima Island.
On the other hand, I came across flowers I had never seen on Yakushima Island, such as Hakoneutsugi. All the Hakoneutsugi flowers I saw today were white. According to a website by the Kyushu Research Center of the Forestry and Forest Products Research Institute, their color gradually changes from white to light crimson, and eventually to crimson. Another type of white flower, the lace shrub, had also started to bloom. I had never seen its tiny flowers on Yakushima either.
I paid attention not only to plants but also to the scenery, as the weather was clear. From near the port in the Motomachi district, Mt. Fuji and the mountains of the Izu Peninsula, such as Mt. Amagi and Mt. Omuro, were clearly visible in the morning. Later, while taking an outdoor public bath there around sunset, I looked again at the highest mountain in Japan.
