Suica on Sony wena 3 launched today according to a JR East press release. The service was announced in October. In addition to Suica, wena 3 also supports iD, QUICPay and Rakuten Edy payments.
wena 3 Mobile Suica is very similar to Garmin Suica with the same Google Pay recharge backend and limitations: no commute plans, etc. Apple Watch Suica is still king of the wearables with a full feature set and PASMO support too, nevertheless Android users, and some iPhone users, will enjoy using Suica on a cool looking device. No word about PASMO support though I expect it will come eventually.
