"Kampai!" is the Japanese equivalent of "Cheers!" If you're travelling through Tokyo, with its vibrant array of sake, shochu, whisky and cocktail bars, this is one word you'll get to know well.
I've been enjoying a new book about this very topic, "Drinking Japan" by Chris Bunting, a Tokyo-based newspaper journalist; a portion of the book's proceeds are donated to Japan Earthquake Relief.
"Post-war Japanese business culture was at least partly built on hard drinking," Bunting says. "The cultural norm was for salary men to spend endless long evenings out on the town with colleagues and clients."
Although that norm has relaxed somewhat, Japan still enjoys a "complex and deeply rooted drinking culture."
However, in order to enjoy Tokyo's watering holes, first you need to find them.
"The best bars are not always the ones that you can see into from the street," Bunting warns.
Further, travellers should know that most bars in Japan have an entrance fee, often levied by giving a small dish of food that has not been ordered by the customer but is put on the bill.
While far from a comprehensive list, here are a few of Bunting's Tokyo picks:
Akaoni 9 is perhaps the best-known premium sake pub in Tokyo, offering more than 100 varieties of the rice-based spirit.
Meanwhile, Shusaron is "quite simply the best place in the world to drink aged sake," in large part due to the encyclopedic knowledge of landlord Nobuhiro Ueno.
The Zen offers a relaxed atmosphere for drinking shochu (an eau-de-vie-like spirit distilled from sweet potatoes, rice or grains).
Drinks are grouped by ingredient and colour-coded: yellow dots signify drinks best served over ice, blue dots recommend serving with ice water, red for warm water and green for straight up).
Japan is famed for its enthusiasm for Scotch and other whiskies. Japanese single malts are also finding international acclaim, with Yamazaki and Hibiki among the best-known brands.
Ken's Bar draws in homesick American business travellers, such as workers from Microsoft Japan's office in Shinjuku, with good jazz and a great selection of Bourbon and other American whiskys.
Don't expect to drink and dash: In Japan, and Tokyo in particular, the art of bartending involves much ritual, from wiping the label of a bottle to hand-carving a perfect sphere out of ice. Tender Bar is the pinnacle of this tea ceremony cocktail aesthetic, under the watchful eye of the legendary Kazuo Uyeda.
