Finding Japanese cuisine that matches up with the authentic, everyday, rustic cuisine of Japan in Bangkok is tough. Way too much here has a high-end, fake feel to it or really bad taste (sometimes in order to attract Thais to it). Azuki on soi 11 was simply superb with a mostly Japanese clientele with a great meal for 350 baht.

 

But with its sudden destruction where else is there to go for a similar experience (with the tatami mats) with tasty, reasonably priced, centrally located Japanese grub?

 

I'm particularly interested in hearing from people who have lived in Japan.

soi thaniya sala daeng is the japanese soi, i bet they have it there

We used to love Hanaya in Bang Rak, but it always used to get very busy.

I'm not knowledgeable about Japanese food in general but in the past two years, the Phra Khanong area has had a bunch of small and inexpensive Japanese restaurants open.  

If you take the BTS to Phra Khanong, take Exit #3 and walk in the direction of traffic.  Take your first left (Suk. 69) and walk 100 meters.. At the corner of the first soi on the right (Suk. 71 soi3) is a longstanding Okinawan restaurant which always seems busy. 

Walking up Soi 3 you will find several Izikaya style places and a sushi joint or two. 

When you get to Sukhumvit 71, if you cross the street and walk left, you will find two and maybe by now three small Japanese restaurants.

If, instead of crossing Suk. 71, you walk to the right, there is a new Japanese place not too far down towards Sukhumvit.
