OTOH, while they're top tier in fountain pens, Germans really equal with them. Lamy, Faber Castell, Diplomat, Kaweco and of course Montblanc make great pens. Pilot & Sailor are not behind them, though. Mitsubishi Pencil bought Lamy so things will get interesting.
Inks are the same. Germans and Japanese are head to head. OTOH, except Leuchttrum and Rhodia, I can't find many fountain pen first papers from Europe.
Funnily, when it comes to fountain pens, there's another interesting contender. China. While they copy most of the stuff, their domestic brands make great pens and ink.
Also, a company in my country started making a paper which rivals Yu-Sari and Tomoe River. I write letters with it, and it's great.
