Solo. Solitary. Alone. The Japanese word for this condition is botchi, short for hitoribotchi, meaning "all on one's own." A decade ago, few people in Japan would admit to being botchi, especially during the holidays -- the unspoken connotations were too awful: Alone on Christmas? What are you, a weirdo? [...] But that was then. Today, botchi has blended into Japan's social fabric to the point where it is considered rude to ask about Christmas Eve plans unless you are someone's mother. And these days, even mothers tread lightly. As societal pressure on Japan's singles eases, their number has risen fast and in an article for the President, a business publication, media columnist, author and "singles expert" Kazuhisa Arakawa cited a government white paper showing that in 2020, the proportion of single-person households across Japan had doubled to 38% since 1980. In Tokyo, the spike in "solos" is even more dramatic—52% of all households consist of just one person, according to the National Institute of Population and Social Security Research.
