Indian skipper Shreyas Iyer termed the track at the Sano International Cricket ground as "difficult to bat on" as he tried to explain his team's struggle in notching a two-run win over unfancied Japan in a one-off T20 International here on Tuesday.

With left-arm spinner Charlie Hara-Hinze and off-spinner Ibrahim Takahashi turning the ball by a country mile, India were restricted to a below-par 32 for 4 in a rain-hit five-overs-a-side match but did well enough to restrict Japan to 30 and avoid what would have been a huge upset.
