Hi Tedongganas,
Wonder if you have come across this Japanese manufacturer by the name of F-Toys Confect?
They have some nice aircraft and ship models in 1/144 scale. Their products are similar to Furuta and Takara.
You can see their current collection on their website
F-toys confect. 【エフトイズ・コンフェクト】
I found one of their series (below) on sale on UK's tank zone website. The float planes look pretty cool huh?
