I recently posted a trip report and it included coverage of the Tanabata Festival as celebrated here in Los Angeles.
During my hunt for information on this festival I read that Tokyo Disneyland celebrates this event.
Wiki had this to say:
I was wondering if any of you fellow Micechatters have experienced this?Tokyo Disneyland often celebrates the Tanabata Festival featuring a greeting parade with Mickey as Altair and Minnie as Vega.
According to the information I read, the biggest celebration happens in the city of Sendai.
With the recent events is that happening this year?
