Trivia fans will probably be aware that there's a designated day for just about everything in Japan, from natto (July 10) to VHS players (October 29). One of the most recent was concocted just last year, when a bunch of sozzled booze bloggers decided that November 11 would hitherto be declared 'Tachinomi no Hi' (standing bar day). Dedicated bar-hoppers can partake in the second ever Tachi-Nomi Tour this weekend, as 130 watering holes in ten different areas around Tokyo offer designated drinks and nibbles for ¥500 a pop (purchasable with a ¥2,000 ticket book). The 'hoods range from central districts like Shibuya and Shimbashi to more out-of-the-way destinations including Koiwa, Tateishi and Kichijoji, making it a good excuse to explore some new areas and get hammered at the same time.
