Hi, I'm Kei Narujima! This is a blog about the flowers, plants, and bugs I find in central Tokyo, along with bits of art and Japanese culture to make you smile or think (or so I hope)! こんにちは。花や虫、そして時々日本の文化などについて書いてます😊。
Beef Jerky at Midnight 真夜中のビーフジャーキー
White-Banded Hunter Hawkmoth (Theretra Oldenlandiae) セスジスズメ(背筋雀)
Impatiens hawkmoths, also known as white-banded hunter hawkmoths (Theretra oldenlandiae), can be found across Japan. Their caterpillars are a beautiful black, creating a stark contrast with their orange spots initially, before turning brownish prior to burrowing into the ground to pupate. They can also sometimes be pale green, as their body color varies depending on temperature and age. While the caterpillars have a chubby appearance, the adults look cool, resembling fighter jets. Adults can be found from May to October in Japan.

Single-Flowered White Sasanqua Camellia with Pink Edges 一重でピンクの縁取りの白山茶花
The Camellia sasanqua is native to, and can be found across, Japan. It produces flowers from October to December (as opposed to the Camellia japonica, which flowers from February to April). The colors vary from white to pink and red and so do the petal forms, ranging from single to double. The blooms in this post are single-flowered and white with pink edges and you can easily spot these blooms in many places across Tokyo. Single-flowered Camellia sasanquas may be less flashy but are as beautiful as the double-flowered ones.

White Magnolia (Yulan Magnolia) ハクモクレン(白木蓮)
Yulan magnolia (Magnolia denudata) is native to central and eastern China but now can be found across Japan and in many places in Tokyo. The tree flowers from February to April, the earliest among magnolias growing in Japan. The flower's pure white creates a brilliant contrast against the blue sky.
Confederate Rose (Hibiscus Mutabilis cv. Versicolor) スイフヨウ(酔芙蓉)
These are Confederate roses (Hibiscus mutabilis cv. versicolor) and the first five photos are of one flower, taken at 10:00, 12:30, 15:30 and 16:30 on 16 September 2024 and at 5:30 on the following morning. After such a color change from pure white in the morning to pink in the afternoon, this type of Confederate roses is named "sui fuyou," which translates into "drunken Confederate rose."

Shovel-Headed Garden Worm (Bipalium Kewense) コウガイビル(笄蛭)
英語の後に日本語が続きます。
This is a shovel-headed garden worm (Bipalium kewense). When I first saw it, I almost screamed. Slowly moving, it looks harmless but it has surprisingly terrifying features.Firstly, it carries tetrodotoxin, the same deadly poison found in pufferfish. Secondly, its mouth is in the middle of its belly and when finding its favorite food, e.g., earthworms, it pushes its stomach outside its body, wraps it around the worm, liquefies it, and drinks it 😱. Thirdly, this worm can split its own body to make clones, so it will not die even if it is cut up.

Grasshopper (Atractomorpha) オンブバッタ(負飛蝗)
Red, White, and Yellow Spider Lily (Lycoris) ヒガンバナ(曼珠沙華/彼岸花)
Spider lilies are native to China but can be found across Japan. They flower in September and therefore are called "Autumnal equinox flower" in Japanese. Spider lilies are known generally as red flowers (Lycoris radiata) but they produce white (Lycoris albiflora) and yellow (Lycoris traubii) flowers. A white spider lily is not a sibling of a red one, but a cross-breed of a red and a yellow spider lilies. It's interesting that a child of red and yellow flowers is white.
Lespedeza (Bush Clovers) 萩(ハギ)
The bush clover is native to east Asia and can be found across Japan. It's known as an autumn plant in Japan and its Japanese name "hagi" is a kigo or a seasonal word or phrase associated with a particular season used in traditional forms of Japanese poetry for autumn, but bush clovers actually flower from July to September and I once found a tree flowering in December (scroll down).

Pink and White Bush Clovers (Lespedeza Buergeri) キハギ(木萩)
Pink and white bush clovers (Lespedeza buergeri) can be found across Japan. Generally, bush clovers produce pink/purple flowers but this type produces flowers which have the large white upper petal (banner) with a base and the two side petals (wings) both of which are purple. Lespedeza buergeri blooms from July to September, making it the earliest to flower among the bush clovers.

Camellia Fruits (Camellia Japonica and Camellia Sasanqua) 椿と山茶花の実
Camellia trees in my neighborhood have started fruit and one of the differences between the Camellia japonica and the Camellia sasanqua is the fruit.

Orange Sweet Osmanthus (Osmanthus Fragrans Var. Aurantiacus) キンモクセイ(金木犀)
Orange sweet osmanthus (Osmanthus fragrans var. aurantiacus), a variety of sweet osmanthus, is native to China and came to Japan in the 17th century. As its name suggests, the flowers are so fragrant that orange sweet osmanthus is designated as one of the three most fragrant flowers in Japan together with winter daphne and cape jasmine.
Autumn Leaves of Flowering Dogwood (Cornus Florida) ハナミズキ(花水木)の紅葉
One of the pleasures in autumn is to enjoy viewing leaves turn red and yellow. My favorite autumn leaves are maple, Chinese tallow, and those in these pictures. Flowering dogwood. It's a bit early for the best season but these orange and red leaves and bright red fruits are beautiful enough.
Chinese Tallow (Triadica Sebifera) 南京櫨(ナンキンハゼ)
The Chinese tallow is one of my favorite plants for its beauty throughout the year, i.e., spike-like green flowers and three-lobed also beautiful green fruits from spring to summer, gorgeous gradients of red, orange, and yellow leaves in autumn (scroll down!), and chubby white seeds covered in capsules, which are green at first but turn black, in winter. The tree is native to China but can be found across Japan. Its leaves offer comfortable habitats to insects, like nettle caterpillars (scroll down) and yellow spotted stink bugs.
Fruits of Cornus Florida (Flowering Dogwood) 花水木(ハナミズキ)の実
These are fruits (drupes) of Cornus florida or dogwood flowers. Their flowers resemble those of Cornus kousa so much that it's not easy to tell but their fruits are completely different. Cornus florida shows unexpectedly gorgeous autumn leaves.

Corchoropsis カラスノゴマ(烏胡麻)
英語の後に日本語が続きます。
Corchoropsis is native to east Asia and can be found across Japan, producing yellow flowers from August to September. There are several types of Corchoropsis in east Asia but Japan has only the type of those in these photos, Corchoropsis crenata Sieb. et Zucc. Its Japanese name is "karasu no goma," which translates into "crow's sesame," after the resemblance of its seeds to sesames and crows eating the seeds.

Japanese Chestnut (Castanea Crenata) 日本グリ(和栗)
Finding a still-green chestnut burr on the ground made me look up at the tree above me. The Japanese chestnut (Castanea crenata) is native to Japan and Korea and can be found across Japan. Chestnuts are used for many dishes in Japan, not only sweets but also mixed rice or kuri gohan.

Blue Mistflower (Conoclinium Coelestinum) アオイロフジバカマ(青色藤袴)
英語の後に日本語が続きます。
The blue mistflower (Conoclinium coelestinum) is native to North America and came to Japan in or after the Meiji period (1868-1912), producing blue flowers from July to October. Its Japanese name is "aoiro fujibakama," which translates into "blue fragrant eupatorium," after its color and resemblance to the fragrant eupatorium flower.![]() |

英語の後に日本語が続きます。
Orange Bracket Fungus (Pycnoporus Coccineus) ヒイロタケ(緋色茸)
Bitter Gourd (Momordica Charantia) ゴーヤ(苦瓜)
Bitter gourds (Momordica charantia) are native to tropical Asia, came to Okinawa, i.e., one of the southern islands in Japan, in the early 15th century, and can now be found across Japan. The gourds are monoecious, which means they produce yellow, male and female flowers from July to August but it's easy to tell because the male has the yellow center while the female has the green center. They usually produce male flowers first to ensure the safe fertilization of the female ones. So, the ratio of male to female in early summer is about 10:1.

Japanese Cornel Dogwood (Cornus Officinalis) サンシュユ(山茱萸)
The Japanese cornel (Cornus officinalis) is native to China, Korea, and Japan and can be found across Japan. The tree produces umbels of bright yellow flowers from March to April and berries that get redder from October to November.
Harlequin Glorybower (Clerodendrum Trichotomum) 臭木(クサギ)
The color combination and contrast of harlequin glorybower's fruits always amazes me. Harlequin glorybower (Clerodendrum trichotomum) is native to east Asia and can be found across Japan, producing white flowers from July to September and fruits from October to November. The plant's Japanese name is "kusagi," which translates into "smelly tree," after its smelly stems and leaves. The fruits are blue, surrounded by red calyxes in autumn, which forms an incredibly beautiful stark color contrast.
Japanese Winterberry (Ilex Serrata) ウメモドキ(梅擬)
Japanese winterberry (Ilex serrata) is native to China and Japan, so can be found across Japan. The winterberry produces cute, tiny (i.e., 3-4 mm in diameter) flowers from May to July and red fruits from September to next January, which turn red.
Sweet Viburnum (Viburnum Odoratissimum) サンゴジュ(珊瑚樹)
Sweet viburnum (Viburnum odoratissimum) is native to Asia and can be found across Japan. The tree produces clusters of white flowers from June to July and red berries from July to October in Japan and because of the color of the berries, the tree's Japanese name is "sango ju," which translates into "coral tree." The berries are beautiful but toxic.

Queen Coralbead (Cocculus Trilobus) アオツヅラフジ(青葛藤)
False Parasol (Chlorophyllum Molybdites) オオシロカラカサタケ(大白唐傘茸)
The false parasol mushroom (Chlorophyllum molybdites) is native to temperate and subtropical regions but can now be found across Japan. The mushroom is beautiful and looks delicious but has poisoned many people...😱 As nicknamed the " vomiter," the mushroom is poisonous, causing literally vomiting and diarrhea!

Crepe Myrtle (Lagerstroemia Indica) サルスベリ(百日紅)
Crepe myrtle (Lagerstroemia indica) is native to China, coming to Japan before the Edo period (1603 - 1867) and can now be found across Japan. The tree produces flowers in various colors, white, pink, and red. Its leaves turn orange and red beautifully in autumn and the dark brown fruits are also beautiful.
- Prosperity;
- Good luck;
- Chastity;
- Good luck in love and marriage; and
- Marital fidelity.
But here in Japan, it means:
- Charm and;
- Carelessness.

Common Straight Swift (Parnara Guttata) イチモンジセセリ(一文字挵)
The common straight swift (Parnara guttata) can be found across, and is loved in, Japan. Moths open wings when resting while most butterflies rest with their wings closed but common straight swift butterflies sometimes rest with open wings to absorb the warmth of the sun, thanks to which I've learned that their back is green (scroll down). Also scroll down to see an ant carrying a dead common straight swift.

Mixed Color Morning Glories 混合色の朝顔(アサガオ)
These are mixed color morning glories. Every color is so beautiful. Morning glories are very popular in Japan. Elementary schools grow morning glories in summer to teach students about plants (I was one such student!) and many municipalities hold morning glory festivals in summer.
You may believe that the plant name morning glory was given because the flowers open in the morning, but that's not true. Morning glory goes to sleep as it gets dark and wakes up (i.e., the flower opens) after nine hours of sleep. They live healthy lives!😉
Skunkvine (Paederia Foetida) 屁糞葛(ヘクソカズラ)
Skunkvine (Paederia foetida) is native to Asia and can be found across Japan. The perception of the plant in Japan is it's smelly (as in other countries), so its Japanese name is "hé kuso kazura," which translates into "fart shxx vine." The plant is also so hardy that an imperial court official in the Nara period (710-794) composed a waka poem that he wanted to work hardily like the plant. The poem is included in The Manyōshū, i.e., the oldest extant collection of Japanese waka poetry compiled during that period.

Shrimp Plant (Justicia Brandegeeana) コエビソウ(小海老草)
Small Copper (Lycaena Phlaeas) ベニシジミ(紅小灰蝶)
英語の後に日本語が続きます。
The small copper (Lycaena phlaeas) flies from March to November in Japan, so it's not unusual to see them but it was my first time to see them, not one but two! Their orange forewings caught my eye. The butterfly's coloration changes slightly across seasons; spring broods are typically brighter while summer ones become darker and more muted. I can't say for sure but one of them seems like a spring brood and the other a summer one. Scroll down to see the two together in a photo.
