The list of Japanese restaurants in Bangkok is staggering, enough to fill an encyclopedia, which isn't surprising given that over 50,000 Japanese expatriates call Bangkok home. With this clientele and demand, it is natural that hundreds of new spots open up each year, but some really stand out for their fresh ingredients and preparation just like in Japan.
Of course leading the list are the top sashimi and sushi joints, all of whom fly in their fish from the prestigious Tsukiji Fish Market in Tokyo, with deliveries to Bangkok several times a week. Heading this list is Sushi Ichizu, who's master chef Riku Toda studied under some of Tokyo's top sushi masters in Michelin-starred omakase eateries, and now runs the elite Sushi Ichizu. Mugendai Penthouse is also noted for its snazzy nouvelle sushi, with some amazing creations such as their Unagi eel foie gras and their Matsuzaka beef sushi. On their tails, Uomasa and Maru also get fresh cuts of tuna and other delicacies, and you wont be complaining about the bill if you are feasting on the top bluefin and fatty tuna slices that are melting in your mouth. Non-traditional sushi rolls have become all the rage but can be pretty hit and miss, but one place that stands out is Isao, which has to be the only restaurant in Bangkok with a line out the door 365 days a year!
Not that it has to be all sushi either. Bankara Ramen is also high on the expat list, with humongous bowls of traditional ramen keeping their tables packed through lunch and dinner. The tonkatsu stewed pork belly is made with the pork bones dissolved completely into the soup broth, extremely pungent and rich. For creative nouvelle Japanese try the new Kom-Ba-Wa or else the creative and sumptuous Zuma.
The listings of Japanese are so numerous, one could probably just stroll down Thonglor night after night and pop in to a new eatery for months and not go wrong.
