A Japanese friend of mine who's lived outside of her home country for the past two decades or so reacted with shock as well as incredulity at the very idea that the super popular unofficial mascot from Funabashi called Funassyi (whose Twitter followers currently number 1.44 million) will be performing in concert at the Nippon Budokan Hall, never mind headlining it. For, as she pointed out to me, this is the very venue where such legendary acts as the Beatles and Rolling Stones had previously graced.
