Question: The studio that produced "Ocean Waves" is based in what country?

Context paragraphs:
Ocean Waves (film): Ocean Waves, also known as I Can Hear the Sea (Japanese: 海がきこえる , Hepburn: Umi ga Kikoeru ) , is a 1993 Japanese anime television film produced by Studio Ghibli.  Directed by Tomomi Mochizuki and written by Kaori Nakamura, the film is based on the novel of the same name by Saeko Himuro.  "Ocean Waves" first aired on May 5, 1993 on Japanese television.

Equatorial wave: Equatorial waves are ocean waves trapped close to the equator, meaning that they decay rapidly away from the equator, but can propagate in the longitudinal and vertical directions.  Wave trapping is the result of the Earth's rotation and its spherical shape which combine to cause the magnitude of the Coriolis force to increase rapidly away from the equator.  Equatorial waves are present in both the tropical atmosphere and ocean and play an important role in the evolution of many climate phenomena such as El Niño.  Many physical processes may excite equatorial waves including, in the case of the atmosphere, diabatic heat release associated with cloud formation, and in the case of the ocean, anomalous changes in the strength or direction of the trade winds.

Tomomi Mochizuki: Tomomi Mochizuki (望月 智充 , Mochizuki Tomomi , born December 31, 1958 in Hokkaidō, Japan) , sometimes incorrectly romanized as Tomomichi Mochizuki, is an anime director and producer.  He is married to animator Masako Gotō and sometimes uses the alias Gō Sakamoto (坂本 郷 , Sakamoto Gō ) when writing screenplays or working on storyboards.  Known from the early 1990s as director of "Ranma ½", "Kimagure Orange Road" and the Studio Ghibli TV movie "Ocean Waves", he is also known for having directed "Twin Spica", "Zettai Shounen", the acclaimed World Masterpiece Theater series "Porphy no Nagai Tabi", and most recently as director of the 2010 noitaminA series "House of Five Leaves".

Studio Ghibli: Studio Ghibli, Inc. (Japanese: 株式会社スタジオジブリ , Hepburn: Kabushiki-gaisha Sutajio Jiburi ) is a Japanese animation film studio based in Koganei, Tokyo, Japan.  The studio is best known for its anime feature films, and has also produced several short films, television commercials, and one television film.  It was founded on 15 June 1985, after the success of "Nausicaä of the Valley of the Wind" (1984), with funding by Tokuma Shoten.

Marine energy: Marine energy or marine power (also sometimes referred to as ocean energy, ocean power, or marine and hydrokinetic energy) refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences.  The movement of water in the world’s oceans creates a vast store of kinetic energy, or energy in motion.  This energy can be harnessed to generate electricity to power homes, transport and industries.

Surface wave: In physics, a surface wave is a mechanical wave that propagates along the interface between differing media.  A common example is gravity waves along the surface of liquids, such as ocean waves.  Gravity waves can also occur within liquids, at the interface between two fluids with different densities.  Elastic surface waves can travel along the surface of solids, such as "Rayleigh" or "Love" waves.  Electromagnetic waves can also propagate as "surface waves" in that they can be guided along a refractive index gradient or along an interface between two media having different dielectric constants.  In radio transmission, a "ground wave" is a guided wave that propagates close to the surface of the Earth.

Microseism: In seismology, a microseism is defined as a faint earth tremor caused by natural phenomena.  Sometimes referred to as a "hum", it should not be confused with the anomalous acoustic phenomenon of the same name.  The term is most commonly used to refer to the dominant background seismic and electromagnetic noise signals on Earth, which are caused by water waves in the oceans and lakes.  Characteristics of microseism are discussed by Bhatt.  Because the ocean wave oscillations are statistically homogenous over several hours, the microseism signal is a long-continuing oscillation of the ground.  The most energetic seismic waves that make up the microseismic field are Rayleigh waves, but Love waves can make up a significant fraction of the wave field, and body waves are also easily detected with arrays.  Because the conversion from the ocean waves to the seismic waves is very weak, the amplitude of ground motions associated to microseisms does not generally exceed 10 micrometers.

Optical rogue waves: Optical rogue waves are rare pulses of light analogous to rogue or freak ocean waves.  The term optical rogue waves was coined to describe rare pulses of broadband light arising during the process of supercontinuum generation—a noise-sensitive nonlinear process in which extremely broadband radiation is generated from a narrowband input waveform—in nonlinear optical fiber.  In this context, optical rogue waves are characterized by an anomalous surplus in energy at particular wavelengths (e.g., those shifted to the red of the input waveform) and/or an unexpected peak power.  These anomalous events have been shown to follow heavy-tailed statistics, also known as L-shaped statistics, fat-tailed statistics, or extreme-value statistics.  These probability distributions are characterized by long tails: large outliers occur rarely, yet much more frequently than expected from Gaussian statistics and intuition.  Such distributions also describe the probabilities of freak ocean waves and various phenomena in both the man-made and natural worlds.  Despite their infrequency, rare events wield significant influence in many systems.  Aside from the statistical similarities, light waves traveling in optical fibers are known to obey the similar mathematics as water waves traveling in the open ocean (the nonlinear Schrödinger equation), supporting the analogy between oceanic rogue waves and their optical counterparts.  More generally, research has exposed a number of different analogies between extreme events in optics and hydrodynamic systems.  A key practical difference is that most optical experiments can be done with a table-top apparatus, offer a high degree of experimental control, and allow data to be acquired extremely rapidly.  Consequently, optical rogue waves are attractive for experimental and theoretical research and have become a highly studied phenomenon.  The particulars of the analogy between extreme waves in optics and hydrodynamics may vary depending on the context, but the existence of rare events and extreme statistics in wave-related phenomena are common ground.

Kinematic wave: In gravity and pressure driven fluid dynamical and geophysical mass flows such as ocean waves, avalanches, debris flows, mud flows, flash floods, etc., kinematic waves are important mathematical tools to understand the basic features of the associated wave phenomena.

Lake surfing: Lake surfing is surfing on any lake with sufficient surface area for wind to produce suitable waves.  As with ocean surfing, ideal wave conditions are when the wind switches offshore.  However, when this occurs over a lake the waves generated by previous onshore wind subside relatively quickly.  This means lake surfers have a shorter window of opportunity to surf ideal waves.  Lake surfers are often out during and experiencing the same storm that creates the waves whereas ocean surfers are more often surfing on swell produced by storms hundreds of miles away and that may have taken days to reach shore.  In addition to making it more difficult to manage surfboards, high winds can make the face of a wave and water surface rough.  Increased wave frequency due to shorter fetch results in less rest between waves and sets of waves.  This can make it necessary to paddle out through waves because there may not be a long enough pause between sets to paddle out between them.  Though not significant enough to necessitate surfboard design changes, the reduced buoyancy of fresh water results in increased drag when paddling.  Lake surfers enjoy water that is fresh ("sweet" as opposed to salty) and do not have to worry about the dangers from marine life (e.g. sharks, jellyfish, etc.) that ocean surfers may have to contend with.
