I was fortunate enough to find both of my Olympic Vigore 17H casting rods at: オリムピック(OLYMPIC) 20 ビゴーレ 20GVIGC-71H 20ビゴーレ(VIGORE)、16ビゴーレ(VIGORE) | 激安釣具通販 ルアーフィッシング キャスターハウス (casterhouse.co.jp)
Unfortunately, Casterhouse.co.jp has been OOS of Vigore casting rods since last summer. Your best bet is probably to seek out a Vigore 71H casting rod on Yahoo.jp auction.
Good luck with your JDM rod search and please have a great day!
