Reading Japanese literature in translation is always an adventure, and when it comes to Kawabata and Mishima, the choice of translator makes all the difference. For Kawabata's 'Snow Country', I'd recommend Edward Seidensticker's translation - his delicate handling of the prose captures that quintessential Japanese melancholy.
With Mishima's 'The Temple of the Golden Pavilion', I find Meredith Weatherby's version particularly gripping. There's this raw intensity in the phrasing that really conveys Mishima's troubled genius. What's fascinating is comparing different translations of the same passage - you can sometimes spot how translators interpret cultural nuances differently.
