‘What makes W&C JPN (Tokyo Office) practice unique is that you have both ENG and JPN Law highly trained, specialised and devoted team of lawyers. Also, they always put the clients front and center above other considerations and ensure at all costs that for every matter, relevant resources are applied and available at all times, and if needed, kept on standby. Also, the team comes from a diverse set of origins, so it’s a good blend when it comes to an end-product (legal service output). In terms of innovations, the networking sessions they set-up (i.e., energy sector market players) regularly are a brilliant idea.’

‘The main partner that works for my organisation is Paul Harrison. In terms of key outstanding qualities, the main would be his synthetic nature and his custom to address immediately the potential major risks and red flags of any particular document, contract, discussion etc. so the client is always well aware of the different angles to be considered before moving ahead with any major decision. On a subsequent basis, he may move for assessment of more detailed and secondary matters. Also, he is extremely talented in devising the least-resistance solutions based on his understanding and background of the parties involved and the precedent applicable transactions. This saves a lot of resources later on as potential solution avenues are put forward for consideration.’
