Take the JR Sanyo Shinkansen from Osaka (Shin-Osaka Station) to Okayama Station and transfer to the JR Marine Liner rapid train to Takamatsu. The entire journey costs about 8,000 yen one way. It takes about two hours if using a Nozomi train along the Sanyo Shinkansen or about 45 minutes longer if using Hikari or Sakura trains. The Japan Rail Pass fully covers Sakura and Hikari trains between Osaka and Okayama, but a supplement fee is required for riding Nozomi and Mizuho trains. Meanwhile the JR Kansai Wide Pass covers all trains.
