St. Mary's Cathedral, Tokyo, Japan

St. Mary's Cathedral is the seat of the Roman Catholic Archdiocese of Tokyo. It is located in the Sekiguchi neighborhood of Bunkyo, Tokyo, Japan.

The plan of the building is in the form of a cross, from which the walls, eight hyperbolic parabolas, rise up at an angle. These open upwards to form a cross of light which continues vertically the length of the four facades. To this rhomboid volume other secondary constructions are added, their rectangular volumes contrasting with the symbolic character of the cathedral with which they communicate by way of pathways and platforms. The baptistry and the baptismal font are among these secondary buildings. The bell tower is 60 m in height and stands at a little distance from the cathedral proper, whose interior is finished in exposed concrete. The exterior surfaces are clad in stainless steel, which gives them a special radiance in keeping with the religious character of the building.

Mode Gakuen Cocoon Tower, Tokyo, Japan

Mode Gakuen Cocoon Tower is a 204-metre (669 ft), 50-story educational facility located in the Nishi-Shinjuku district in Shinjuku, Tokyo, Japan. Completed in October 2008, the tower is the second-tallest educational building in the world and is the 17th-tallest building in Tokyo. It was awarded the 2008 Skyscraper of the Year by Emporis.com.

The building's cocoon shape symbolizes a building that nurtures the students inside. White aluminum and dark blue glass exterior form the structure's curved shell, which is criss-crossed by a web of white diagonal lines earning it the name "Cocoon Tower".

Mode-Gakuen Spiral Towers, Nagoya, Japan

Mode-Gakuen Spiral Towers located in busy Main Street of Nagoya city in front of Nagoya Station. The towers are 170-metre (558 ft), 36-story tall and are designed for three schools that represent the school of fashion design, computer programming and medical support. The concept of the towers are derived from the enthusiasm of students from three schools, twining and rising up to the sky then departing to the real world. Three buildings of class rooms around the spiral core are called “Wings”. The towers' wing-like shape, narrow at the top, changes the rotation axis as they rise and create an organic curve. Spiral Towers appears to change shape slightly when viewed from different angles, giving an elegant yet dynamic impression. The strong inner truss tube is visible through gaps between the three wings, highlighting the bold design and structure while demonstrating the overall consistency.

The towers are highlighted with many ecological features, such as a double-glassed air flow window system and a natural air ventilation system. The central core of the building is a highly rigid cylindrical structure. Like the central pillar in a house, this structure securely protects the building against twisting and earthquakes. This cylindrical structure is called an inner truss tube and comprises concrete-filled, steel tubular columns, with braces deployed around the core. The towers are integrated with mass damper systems, expanding columns and AMD for restraining seismic vibration. The latest structural engineering provides the highest safety even in the case of the more severe earthquakes.
