Thanks to Dunechaser of Pan-Pacific Bricks for helping explain some of the cultural references in these Japanese vigs. Yesterday was Tanabata, a summer holiday that traditionally involves decorating bamboo with cards and streamers. Two builders depict this: Inago100's Tanabata and Mumu's wife's Star Festival.
A vig from Mumu called Somen depicts a trendy noodle restaurant in which the noodles are served floating in a little stream past the diners.
Finally, Turbo depicts a carnival game typically played at festivals with goldfish catching.
Thanks, Dunechaser, for helping explain the context behind these on Pan-Pacific Bricks.
