Oblon Tokyo Office Celebrates 10th Anniversary

  • Firm News

Oblon celebrated the 10th anniversary of the opening of the Oblon Tokyo Office with a lunch-reception attended by over 60 client guests. Thank you for your support!

Highlights of the gathering included a piano performance by Partner Yuki Onoe, Head of the Tokyo Office; background music by Senior Advisor Dr. Hohokabe (recorded 50 years ago!); and a speech by Managing Partner Philippe Signore. Most importantly, it was an occasion to share a meal, drinks and stories between Oblon professionals (pictured) and clients at the beautiful venue of Hotel Chinzano.
