The Southeast Asian nation is aiming to raise as much as $1 billion via Samurai bonds this year as part of the financing programme for its $180 billion "Build, Build, Build" infrastructure development plan.

Pricing is on August 8, but may be pushed back about one week, according to IFR, a Thomson Reuters unit, citing the registration statement.

The Philippines last visited the yen market in 2010 with a 10-year bond issue that raised 100 billion yen, with a guarantee from Japan Bank for International Cooperation, IFR said.

There was no such guarantee for the upcoming issue, it said.
