Among the promos they're doing for the Japanese Launch of WoT is playing at this maid cafe (redone as a Tank Cafe) against Duck Team's seiyuu, as well as Hana & Yukari's seiyuu.
Also, during Tokyo Game Show, there will be a GuP/WoT talk show called "Russian Tanks Are The Best", starring Sumire Uesaka, aka Nonna. XD
