The English for “Tanabata” is Star Festival. According to reagent two stars (Altari and vega) were separated by the milky way but once a year they can reunite on July 7th. At the day people write their wishes on paper and then hung them on bamboo. In Tokyo, there are a lot of interesting events. If you go to Tokyo tower, you can enjoy to see decoration of the milky way until July 7th. Also you can have fun Star Festival at Roppongi Hills, Shinagawa Aquarium and Tokyo Disneyland. I recommend you will go those places like Tokyo tower with your boyfriend. You will have lots of fun!
