Place to buy Japanese woodworking tools

Hello fellow redditors,

German guy here. I'm in Thailand for one month and will spent my last two days in Bangkok. I wonder if anyone knows a place where i could buy Japanese woodworking tools like a Kote Nomi as seen in the picture, a hand planer or tools like that. 

I know Thailand is not Japan but still it would make a nice souvenir. 

Recommendations would be greatly appreciated :)
