I just went through this with mine, replacing the wiper blades and one J-hook arm. I used NWB brand wipers:
NWB PRODUCT NR27 Wiper
純正採用率No.1!NWBワイパーのブレードおよび替えゴムの製品情報サイトです。車種別適用検索や各種交換方法、ワイパーに関する知識などをご覧いただけます。www.nwb.co.jp
Advance Auto Parts has these online, and you can get the j-hook arms from main cruiser sources.
NWB is the OEM for Toyota.
