Translation guide
The English idiom 'grasp at straws' describes a desperate attempt to find hope or a solution when options are scarce, often by clutching at weak or unlikely possibilities. In Japanese, there is no single direct idiom, but several expressions and strategies convey similar desperation, depending on context.
Expressing that someone is trying anything, even unlikely things, out of desperation.
Literally 'the feeling of clinging even to a straw'. This is the closest Japanese equivalent to 'grasp at straws', used when someone is so desperate they'll rely on anything, no matter how unreliable.
彼は藁にもすがる思いで、その怪しい治療法を試した。
He tried that dubious treatment, grasping at straws.
When someone is making flimsy or illogical arguments out of desperation.
Means 'to make a strained excuse'. Used when someone is grasping at straws to justify themselves.
彼は苦しい言い訳をして、自分のミスを認めようとしなかった。

Both relate to the straw metaphor. 藁にもすがる思い describes the feeling of desperation, while 溺れる者は藁をも掴む is a proverb stating a general truth. Use the former for personal feelings, the latter for commenting on situations.
