Chinese cucumbers (Trichosanthes kirilowii) are native to China and Japan. They're dioecious, producing white "hairy" flowers from June to September and fruits from August to October. The fruits are green at first and then turn yellow. They're edible but not tasty. Someone says on the internet that he would never eat it unless famine comes😆. It's not so difficult to find Chinese cucumber flowers in Tokyo but not so when it comes to the fruits. It seems Chinese cucumbers are removed when the flower season is over.
When you see the flowers, you would likely see pumpkin beetles (Aulacophora nigripennis), too. Pumpkin beetles are harmful but their tininess, agility and color contrast between orange and black never fails to bring me a smile.

黄烏瓜（キカラスウリ）です。6月から9月に花を、8月から10月に実を付けます。最初緑色の果実は熟すと黄色になるのですがまずい（つまり食べられることは食べられる）。あるネット情報によると「飢饉にならない限り食べない😆」（ぐらいまずい）そうです。
ちなみに黄烏瓜の花あるところに黒瓜葉虫（クロウリハムシ）あり。クロウリハムシはちっちゃいけど敏捷で（スタコラサッサの逃げ足）、とてもきれいです。見るといつも幸せな気持ちになります。

I just found this plant growing at the side of the road in Joetsu, Niigata prefecture. Thought it was a kind of passionfruit, but turns out it's a kind of cucumber. It's not found in New Zealand, so I was curious to identify it. Doug
返信削除Doug, thanks for your comment. The Chinese cucumber seems to grow mainly (and maybe only?) in Asia (i.e., China, Korea and Japan), so I'm happy that you were able to identify the plant! I also hope you enjoyed your stay (maybe skiing?) in Joetsu!
