Natto – Nattō is a close relative of Hawaijar.
Nattō (なっとう or 納豆?) is a traditional Japanese food made from soybeans fermented with Bacillus subtilis var. I have been searching where we can get this stuff in Singapore. There might be other japanese food markets or marts in Singapore depending on where you are, I recently found a store which is quite near to my place.
These are available at J – Mart – Japanese Food Market at One KM Mall located at –
11 Tanjong Katong Road
