As yen-dollar exchange rate exceeds JPY100 for the first time in four years, Korean major industries, which are at in competition with Japanese rivals, for instance, vehicle, shipbuilding, steel, electric industries and etc., appear to face a challenge.
When Japanese companies take action of price reduction, backed by a weak yen, Korean ones could receive a directly hit, such as decreasing exports, low profitability and so on.  
Market players express concerns over shipbuilding industry that immediate export hit from a weak yen might not be dramatic, however, an adverse effect is expected to come to domestic corporations in the long haul.  
Japan is currently welcoming remarkably increased new order intakes from foreign shipowners thanks to a low exchange rate of the yen, which seems a direct threat to small and medium sized shipbuilders majoring in bulker.
In terms of large builders, they focus on high-value vessels/facilities, such as very large containership, LNG carrier, offshore plant and etc. that weak yen alert is quite less prominent to them, however if weak yen gets protracted and Japanese builders have price competitiveness together with advance technology, Korean shipbuilding industry will be suffered from the influences.
