Even Reiwa is a new player of the market, it was decorated and designed in an old-fashioned and modern/traditional Japanese style. However, it has potential to be the most classic and hidden Izakaya in such a turbulent district like Ari, Bangkok. There is no deny that most of the Thai people are likely to go to places where are more photogenic, Bangkoky and appealing to younger generations. But, what if, there is a real Japanese place where people are treated in Japanese way, filled with Japanese food and covered with original Japanese vibes. It is time to authenticate Japan in Bangkok and it is the matter of the arts of authenticity.
